Direct answer
The right static analysis tool is decided by five constraints, not by a ranking: the languages in your repository, your deployment model, the licence, the pricing unit, and whether the tier you can afford can actually gate a merge. Of 17 static analysis vendors we checked on 2026-10-18, only 6 publish a list price you can read without contacting sales. That alone reshapes most shortlists.
Best static analysis tools for finding code bugs
Direct answer: For general bug-finding across a mixed codebase, SonarQube has the deepest rule coverage, Semgrep is the best at rules you write yourself, and Codacy and DeepSource are the fastest to a working merge gate. For C and C++ specifically, Coverity and PVS-Studio go deeper than any of them. Verified 2026-10-18.
There is no single best tool, and a guide that names one is guessing about your constraints. What there is, is a small number of tools that are clearly the right answer to a clearly stated question. Here is the whole field as rows, with the attributes that actually decide a purchase as columns.
| Tool | Pricing unit | Published list price (2026-10-18) | Deployment | Licence | Can gate a PR |
|---|---|---|---|---|---|
| Semgrep | Per contributor | Teams $30/contributor/mo (Code) | Cloud platform; CE binary runs anywhere | CE is LGPL-2.1; Pro engine proprietary | Yes |
| SonarQube Cloud | Lines of code | Team from $34/mo up to 100k LOC | Cloud | Commercial | Yes, including free tier |
| SonarQube Server | Lines of code, per instance/yr | None published | Self-hosted, air-gap capable | Commercial (Community Build LGPL-3.0) | Developer Edition and above |
| Codacy | Per developer | Team $18/dev/mo yearly, $21 monthly | Cloud; self-hosted for GHES | Commercial | Yes |
| DeepSource | Per user + per LOC | Team $24/user/mo yearly; AI review $8 per 10K LOC | Cloud; self-hosted on Enterprise | Commercial | Yes |
| Qlty | Per contributor | Pro $20, Enterprise $30/contributor/mo | Cloud | CLI is fair source (BSL 1.1), not open source | Yes |
| Snyk Code | Projects, then credits | Team from $25/mo | Cloud (Broker is a tunnel, not on-prem) | Commercial | Yes |
| Qodana | Per contributor | Not readable at source | Cloud and self-hosted | Commercial | Yes |
| CodeFactor | Per private repository | Not readable at source | Cloud | Commercial | Yes |
| Coverity (Black Duck) | Quote | None published | Self-hosted and cloud | Commercial | Yes |
| Checkmarx | Quote | None published | Cloud and self-hosted | Commercial | Yes |
| Veracode | Quote | None published | Cloud | Commercial | Yes |
| Fortify | Quote | None published | Self-hosted and cloud | Commercial | Yes |
| Klocwork (Perforce) | Quote | None published | Self-hosted | Commercial | Yes |
| Helix QAC (Perforce) | Quote | None published | Self-hosted | Commercial | Yes |
| Parasoft C/C++test | Quote | None published | Self-hosted | Commercial | Yes |
| PVS-Studio | Quote | None published; free for OSS, students, MVPs | Self-hosted | Commercial | Yes |
6 of 17 publish a readable list price. That is the finding buyers should take from this table before any feature comparison. The 11 that do not are, with the exception of Qodana and CodeFactor (whose pages render prices client-side and returned nothing to us), all enterprise security vendors selling into a procurement process where the price is a function of how much they think you can pay.
For the depth comparison behind these rows, our definitive static code analysis tools guide covers 20+ tools by methodology, and 32 SAST tools reviewed goes deeper on the security-specific field.
Best static code analysis tools for a development team
Direct answer: For a team of 5 to 50, pick on time-to-gate and pricing unit, not rule count. Codacy and DeepSource connect a repository and produce a working PR gate in under an hour. SonarQube Cloud’s free tier gates pull requests up to 50k LOC on private projects and never expires. Verified 2026-10-18.
A development team buying its first static analysis platform is making a workflow decision disguised as a tooling decision. Three questions settle it.
Does the free tier gate pull requests, or only report? This is where the market’s most common confusion lives. SonarQube Community Build - the self-hosted free edition - analyses the main branch only and cannot analyse pull requests. Developer Edition is the minimum for branch and pull request analysis (Sonar’s own documentation, verified 2026-10-18). SonarQube Cloud’s free tier does include pull request analysis, up to 50k LOC on private projects, and it never expires (sonarsource.com/plans-and-pricing, verified 2026-10-18). Same brand, opposite answer. Teams download Community Build expecting a PR gate and discover weeks later that they bought nothing of the kind.
Does the pricing unit match the shape of your team? Per-contributor pricing (Semgrep, Qlty, Codacy) tracks headcount. Per-LOC pricing (SonarQube) tracks codebase age. A six-person team maintaining 4 million lines of inherited code pays very little on the first model and a great deal on the second. A forty-person team on a 200k-line product pays the reverse. Work out which you are before you shortlist, because this difference is larger than any feature gap on the page.
Who owns the config? Tools that keep the ruleset in a repository file (.semgrep.yml, .deepsource.toml, qlty.toml, sonar-project.properties) make every rule change a reviewed diff. Tools that keep it in a web UI make it invisible. For a team, this matters more at month six than at week one.
My default recommendation for a team with no incumbent: Codacy Team at $18 per developer per month billed yearly, capped at 30 developers and 100 private repositories, free forever for open-source projects (verified at codacy.com/pricing, 2026-10-18). It is the lowest published entry price among managed multi-language platforms and it auto-detects languages on connect. The caveat to know: Codacy’s AI Reviewer is cloud-and-GitHub only, so GitHub Enterprise Server customers, who need Codacy Self-hosted, structurally cannot get that component.
Static analysis tools that support multiple programming languages
Direct answer: Codacy lists 49 languages on its Team tier, SonarQube Cloud Enterprise advertises 45+, and Coverity covers 22 languages across 250+ frameworks. SonarQube Community Build covers 21 and excludes C, C++, Swift, Dart, T-SQL and PL/SQL, which is the most consequential gap in any free tier here. Verified 2026-10-18.
Language counts are the most inflated number in this market, because “supported” covers everything from full taint analysis to a syntax highlighter. Three things to check behind the count.
Depth tiers. Semgrep publishes a per-language maturity matrix rather than one number, which is the honest way to do it: a language can be generally available for pattern matching and still lack cross-file support. Always look for the matrix, not the headline.
What the free tier excludes. This is where the real gap is. Sonar’s open source edition page states that upgrading from Community Build is what adds C, C++, Dart, Swift, T-SQL and PL/SQL, along with taint analysis and secrets detection (sonarsource.com, verified 2026-10-18). If you are a C++ shop evaluating SonarQube, the free edition does not analyse your language at all.
Whether multi-language means one engine or several. Codacy and Qlty orchestrate existing open source linters per language; SonarQube and Coverity run their own engines. The orchestration model gets breadth fast and inherits each linter’s quirks. The single-engine model is more consistent and slower to add languages.
| Vendor | Stated language coverage | Source of the number | Notable exclusions |
|---|---|---|---|
| Codacy Team | 49 languages (38 in the free Developer tier) | Vendor pricing page, verified 2026-10-18 | None stated at tier level |
| SonarQube Cloud Enterprise | 45+ languages | Vendor plans page, verified 2026-10-18 | AI agents are Enterprise-only |
| Coverity (Black Duck) | 22 languages, 250+ frameworks | Vendor product page, verified 2026-10-18 | Quote-only pricing |
| SonarQube Community Build | 21 languages | Vendor open source edition page, verified 2026-10-18 | C, C++, Swift, Dart, T-SQL, PL/SQL |
| Semgrep | Per-language maturity matrix, no single count | Vendor docs | Interfile taint requires the Pro engine |
| Opengrep | 12 languages for higher-order taint flow | Project README, verified 2026-10-18 | No interfile taint claimed |
We have language-specific breakdowns for TypeScript, Go, Rust, C#, Kotlin, Swift, Scala, JavaScript and Python.
Best static analysis tool for a legacy codebase
Direct answer: The tool matters less than the baseline feature. Pick anything that supports diff-scoped gating and a frozen baseline: SonarQube’s new code period, Semgrep’s
--baseline-commit, DeepSource’s existing-issue baseline, Qlty’s diff analysis. On a large old codebase, prefer per-contributor pricing over per-LOC, because the bill tracks team size instead of accumulated history. Verified 2026-10-18.
Two decisions, in this order.
Decision one: can it ratchet? Point any modern analyser at a decade-old codebase and you will get a five-figure finding count. The tool is only useful if it can freeze that total and enforce only on changed lines. Every tool listed in this guide can do some version of this, but the names differ and so does the default: SonarQube calls it the new code period and makes it central to the product, Semgrep implements it as --baseline-commit in CI, and most language-native linters need a suppressions file you generate once. Ask for a demo of this specific feature, not of the dashboard. Our static code analysis explainer covers the adoption pattern in detail.
Decision two: does the pricing unit punish you for the codebase’s age? This is the sharpest practical consequence of the pricing models in this market. SonarQube Server is priced per instance per year based on lines of code. A legacy monolith is, by definition, a lot of lines - frequently including generated code, vendored dependencies and dead modules nobody has deleted. Per-contributor models (Semgrep at $30, Qlty at $20, Codacy at $18) are indifferent to all of it.
Two practical notes for legacy work. First, exclusion patterns are a budget lever as well as a noise lever on LOC-priced tools - excluding generated and vendored directories reduces both the finding count and the bill. Second, build-dependent analysers (Coverity, Klocwork, clang-tidy, SpotBugs) need a working build, and reproducing a fifteen-year-old build inside a scanner container is the most common reason legacy static analysis rollouts stall. Source-only engines like Semgrep sidestep that entirely, at the cost of weaker type resolution.
Static analysis tools for C++ code
Direct answer: C++ is the one language where the expensive proprietary tools remain clearly ahead. Coverity (now Black Duck, 22 languages and 250+ frameworks) and PVS-Studio are the depth leaders, Helix QAC and Parasoft own MISRA and AUTOSAR compliance, and cppcheck plus clang-tidy are the free baseline. Note that SonarQube Community Build does not analyse C++ at all. Verified 2026-10-18.
C and C++ are the oldest and most serious market in static analysis, because the language gives you memory safety errors that no runtime will catch for you. The tooling reflects that, and so does the pricing: not one of the C++ depth leaders publishes a list price.
| Tool | Licence / cost | Strength | Published price |
|---|---|---|---|
| Coverity (Black Duck) | Commercial | Interprocedural defect detection at scale, 250+ frameworks | Quote only (verified 2026-10-18) |
| PVS-Studio | Commercial; free for OSS, students, MVPs | Deep C/C++ diagnostics, strong false-positive tuning | Quote-request form only (verified 2026-10-18) |
| Helix QAC (Perforce) | Commercial | MISRA, AUTOSAR, CERT C/C++ certification evidence | Quote only |
| Parasoft C/C++test | Commercial | Safety-critical compliance, unit test generation | Quote only |
| Klocwork (Perforce) | Commercial | Desktop-to-CI incremental analysis on large C/C++ | Quote only; pricing URL returned 404 on 2026-10-18 |
| SonarQube Developer Edition and above | Commercial | Quality gate plus C/C++ analysis via build wrapper | Per instance per year by LOC, no figures published |
| cppcheck | Open source (GPL) | Zero-cost baseline, catches real undefined behaviour | Free; Premium pricing page 404 on 2026-10-18 |
| clang-tidy / Clang Static Analyzer | Open source (Apache 2.0 with LLVM exception) | Compiler-integrated checks, modernisation fixits | Free |
| CodeChecker | Open source | Web UI and triage workflow over the Clang analysers | Free |
Two buying notes specific to C++.
If you are in automotive, medical, avionics or industrial control, the question is not detection quality but whether the vendor supplies certification evidence for MISRA C:2012, MISRA C++:2023, AUTOSAR C++14 or CERT. That requirement eliminates most of the general-purpose market immediately and leaves Helix QAC, Parasoft, Coverity and LDRA. Expect a tool qualification kit to be a separate line item.
If you are not in a regulated domain, start free. cppcheck plus clang-tidy plus -Wall -Wextra -Werror plus the sanitizers at test time covers a surprising share of what the commercial tools find, at zero licence cost. Buy depth when you can point at a class of defect the free stack is missing, not before.
Note that we do not yet have a dedicated C++ language page on this site; this section is currently the most detailed C++ coverage we publish.
Best static analysis tools for Java projects
Direct answer: For Java, SonarQube is the default and Java is included in the free Community Build’s 21 languages. The free stack of Error Prone, SpotBugs with Find Security Bugs, PMD and Checkstyle is unusually strong. Add Semgrep or CodeQL when you need interfile taint analysis. Verified 2026-10-18.
Java has the best free static analysis of any mainstream language, which changes what you should pay for.
Error Prone (Google, Apache 2.0) is the one most teams underuse. It hooks into javac and runs at compile time, so findings arrive as build errors rather than as a dashboard nobody opens. Its NullAway extension gives you practical null-safety enforcement on an existing codebase with annotations. Being a compiler plugin, it has full type information, which is why its false-positive rate is low enough to run as -Werror.
SpotBugs (LGPL, the maintained successor to FindBugs) analyses bytecode rather than source, so it sees what the compiler actually produced, including things erased from the source view. The Find Security Bugs plugin adds roughly 140 security bug patterns and is the free baseline for Java security scanning.
PMD (BSD) and Checkstyle (LGPL) handle source-level rules and conventions. Both are easy to extend with XPath-based custom rules, which is the cheapest way to encode team-specific invariants in a Java codebase.
SonarQube is the paid default, and for Java the free Community Build is actually usable because Java is one of its 21 included languages - unlike C++. The limit to plan around is the one above: Community Build cannot analyse pull requests, so you get analysis without a gate until Developer Edition.
For interfile taint analysis in Java, your options are the Semgrep Pro engine (interfile: true), SonarQube Developer Edition and above, CodeQL via GitHub code scanning, or one of the enterprise SAST platforms. There is no open source option, which is covered in detail in static code analysis explained.
JetBrains Qodana deserves a mention for Java and Kotlin shops because it runs the same inspections as IntelliJ IDEA, so CI findings match what developers already see in the editor. We could not read Qodana’s list prices at source on 2026-10-18 because the pricing page renders client-side, so we are not quoting a figure.
How static analysis is priced, and why the unit matters more than the number
Direct answer: Four pricing units exist in this market: per developer or contributor, per line of code, per private repository, and pay-as-you-go metered. Static analysis is one of the few corners of the code review market where per-repository and metered models still exist. The same codebase can differ by an order of magnitude depending on which unit you sign. Verified 2026-10-18.
| Unit | Who uses it | Verified figure (2026-10-18) | Scales with |
|---|---|---|---|
| Per contributor / developer | Codacy, Semgrep, Qlty, DeepSource, Snyk Team | Codacy $18/dev/mo yearly; Semgrep $30/contributor/mo; Qlty $20 Pro / $30 Enterprise; DeepSource $24/user/mo | Team size |
| Per line of code | SonarQube Cloud and Server | Cloud Team from $34/mo up to 100k LOC; free to 50k LOC private | Codebase size and age |
| Per private repository | CodeFactor | ”Straightforward pricing based on number of private repositories” - figures render client-side, not readable at source | Repo count |
| Metered / pay-as-you-go | DeepSource AI review, Snyk Enterprise credits, Macroscope | DeepSource $8 per 10K LOC (Standard), $15 per 10K (Advanced); Snyk 1 credit = $1, Code at 1.0 credit per active contributor per day; Macroscope $0.025 to $0.20 per KB | Actual usage |
| Quote only | Coverity, Checkmarx, Fortify, Veracode, Klocwork, Helix QAC, Parasoft, PVS-Studio, SonarQube Server | No published figures | Negotiation |
Three observations worth more than the numbers.
Per-repository pricing has nearly died out and still suits one buyer. CodeFactor is the clearest surviving example, and its own pricing page describes the model as “straightforward pricing based on number of private repositories” (verified 2026-10-18, though the dollar figures are injected client-side and we could not read them). This model is good for a large team working in a small number of repositories, which is exactly the monolith case, and bad for microservice estates.
Metered pricing is honest and hard to forecast. DeepSource’s AI review at $8 per 10K processed LOC means a quiet month costs nothing, and it also means nobody can tell you the annual number in advance. Budget owners hate this more than engineers expect. If you go metered, set a hard spend cap on day one.
Per-LOC pricing makes exclusion rules a financial control. On SonarQube, excluding generated code, vendored dependencies and migrations from analysis lowers both the noise and the invoice. Make that part of the implementation plan, not an afterthought.
For how this compares with the AI reviewer side of the stack, see the AI code review price book 2026, which normalises 24 tools three different ways.
Deployment model: cloud, self-hosted, and actually air-gapped
Direct answer: Three levels, and vendors blur them. True air-gap: SonarQube Server, Coverity, Fortify, Klocwork, Helix QAC, Parasoft. Self-hosted with caveats: Codacy Self-hosted, DeepSource Enterprise, Qodana. Not self-hosted despite appearances: Semgrep’s Network Broker and Snyk Broker are tunnels to the vendor’s cloud. Verified 2026-10-18.
This is the distinction most comparison tables get wrong, and it is a hard requirement rather than a preference for defence, health and financial buyers.
Level 1, genuine on-premises and air-gap capable. SonarQube Server runs entirely inside your network and its core SAST engine never phones home. Its AI CodeFix is documented as designed to operate without outbound internet access, naming Ollama, LiteLLM and vLLM as model backends, which makes it the strongest documented air-gap plus bring-your-own-model combination in this market. The traditional enterprise SAST platforms (Coverity, Fortify, Klocwork, Helix QAC, Parasoft) are all on-premises products by origin.
Level 2, self-hosted with conditions. Codacy offers a self-hosted deployment, which is required for GitHub Enterprise Server - with the consequence that GHES customers cannot get Codacy’s cloud-only AI Reviewer. DeepSource self-hosting is an Enterprise-tier item; note that DeepSource has been a Harness product since 9 September 2026, so confirm current terms rather than relying on pre-acquisition documentation.
Level 3, cloud with a tunnel, marketed as if it were more. Semgrep’s Network Broker is a WireGuard tunnel to Semgrep’s cloud, not an on-premises deployment. Snyk Broker follows the same pattern. Both are legitimate products and neither is on-prem. If your requirement is that source code never leaves your network, these do not meet it. Also worth knowing: Semgrep Inc. is explicitly not ISO 27001 certified per its own documentation, contradicting several aggregator profiles that claim otherwise.
The one thing I would tell every regulated buyer: verify against the vendor’s own trust centre, never against a comparison table, including this one. “HIPAA certified” is not a real certification scheme - HIPAA requires a signed BAA, and SOC 2 alone does not satisfy it.
Licence: read it, because fair source is not open source
Direct answer: Three licence classes matter. Genuinely open source: Semgrep CE (LGPL-2.1), Opengrep (LGPL-2.1), SonarQube Community Build (LGPL-3.0), cppcheck, clang-tidy, SpotBugs, PMD, Checkstyle, Error Prone. Fair source, not open source: Qlty’s CLI is BSL 1.1. Proprietary: everything else, including every interfile taint engine. Verified 2026-10-18.
Qlty is the one to get right, because it is frequently miscategorised. Qlty’s CLI is fair source under BSL 1.1, not open source. Qlty’s own site describes the CLI as open and extensible and links a Fair Source explainer in the footer; “open” in that sentence is not an OSI licence. If your procurement process has an open source requirement, or your legal team screens on OSI approval, Qlty’s CLI will not pass as open source and should not be listed as such.
The other licence fact worth carrying into a purchase: interfile taint analysis plus an open source licence does not exist in this market as of 2026-10-18. Semgrep’s documentation states that Community Edition “can only analyze interactions within a single function”, and Opengrep’s LGPL-2.1 fork matches --pro-intrafile with --taint-intrafile but does not claim cross-file taint. If cross-file taint is a requirement, you are buying proprietary software, and the only question is from whom. Our open source AI code review tools roundup covers the equivalent question on the AI side.

What we could not verify, and are therefore not stating as fact:
- CodeFactor’s actual prices. The page injects them client-side as template variables. Third-party aggregators report an entry tier around $19 per month; we could not confirm that at source and are not asserting it.
- JetBrains Qodana’s list prices. Same problem: the buy page renders client-side and returned no figures on 2026-10-18.
- Cppcheck Premium prices.
cppchecksolutions.com/pricing/redirects tocppcheck.com/pricing/, which returned HTTP 404 on 2026-10-18. - Klocwork and Helix QAC prices.
perforce.com/products/klocwork/pricingreturned HTTP 404 on 2026-10-18. Both are quote-only. - Checkmarx, Fortify, Veracode and Parasoft prices. None published. Figures circulating in aggregator listings are third-party and we do not repeat them.
- Any independent precision or false-positive measurement for a commercial AI code reviewer. None exists. Every published benchmark in that adjacent market was funded by a vendor that wins it, with the partial exception of academic work measuring bare models rather than shipping products.
Recommendations
Criteria used: published pricing we could read at source, ability to gate a merge on new code only, language fit, and a licence that matches what the vendor calls it.
Best default for a development team, 5 to 50 engineers: Codacy Team at $18 per developer per month billed yearly. Lowest published entry price among managed multi-language platforms, auto-detects languages, free forever for open source. The exclusion to know is that the AI Reviewer is cloud-and-GitHub only.
Best free tier that actually gates a pull request: SonarQube Cloud. Up to 50k LOC on private projects, PR analysis included, never expires. Do not confuse it with Community Build, which cannot analyse pull requests at all.
Best for writing your own rules: Semgrep. Rules are readable YAML, the CE binary runs in CI with no account, and the hosted free tier gives you the interfile engine up to 10 contributors. Remember that Network Broker is a tunnel, not on-prem.
Best for air-gapped and regulated environments: SonarQube Server. The core engine runs fully on-premises and AI CodeFix is documented to work without outbound internet access with Ollama, LiteLLM or vLLM. Budget for Developer Edition minimum and expect a quote rather than a list price.
Best for C and C++: Coverity or PVS-Studio for depth, Helix QAC or Parasoft if you need MISRA or AUTOSAR certification evidence. Start with cppcheck and clang-tidy and only buy when you can name the defect class the free stack misses.
Best for Java: the free stack first - Error Prone with NullAway, SpotBugs with Find Security Bugs, PMD, Checkstyle - then SonarQube when you want a gate with history, then Semgrep Pro or CodeQL when you need interfile taint.
Best metered option if your volume is spiky: DeepSource, at $8 per 10K processed LOC for AI review on top of a $24 seat, free on public repositories. Set a spend cap on day one.
What I would not buy: an enterprise SAST platform with a quote-only price, before you have run the free stack for a quarter and can point at a specific class of defect it is missing. The free tier of this category is strong enough that the burden of proof is on the invoice.

What should I check before buying static code analysis software?
Six things, in this order. One: does it support every language in the repository you actually want scanned, at the depth you need, not just on the marketing list. Two: can it gate a merge, and can that gate be scoped to new code only. Three: deployment model, because cloud, self-hosted and air-gapped are three different products and vendors blur them. Four: the licence, read rather than assumed, since fair source is not open source. Five: the pricing unit, because per developer, per line of code, per repository and pay-as-you-go produce wildly different bills on the same codebase. Six: run it on your own repository before signing, because published false-positive figures are measured on someone else's code.
Static code analysis tools with pay-as-you-go pricing
Three models qualify as of 2026-10-18. DeepSource bills AI review per processed line of code at $8 per 10K LOC on Standard and $15 per 10K on Advanced, with a $100 annual AI credit per user, on top of a $24 per user per month seat. Snyk Enterprise is a prepaid credit platform subscription where 1 credit equals $1 and Snyk Code is metered at 1.0 credit per active contributor per day. SonarQube Cloud is effectively pay-for-what-you-analyse, priced in lines-of-code bands from $34 per month for up to 100k LOC. Macroscope prices AI review purely by volume at $0.025 to $0.20 per KB depending on mode, with no seat fee at all.
Cheapest static code analysis software for a company
The cheapest credible setup costs nothing. Language-native linters (ESLint, Ruff, golangci-lint, Clippy, RuboCop) plus Semgrep Community Edition in CI cover most correctness and a good share of security for zero licence cost, with the limitation that Semgrep CE cannot do interfile taint analysis. The cheapest managed option with a quality gate is SonarQube Cloud's free tier: up to 50k lines of code on private projects, including pull request analysis, and it never expires. Codacy's Developer tier is free forever but IDE-focused. If you need a gate above 50k LOC, Codacy Team at $18 per developer per month billed yearly is the lowest published entry price among managed platforms we could verify at source on 2026-10-18.
Where can I buy static code analysis software?
Three routes. Self-serve by credit card on the vendor's site covers Codacy, Semgrep Teams, Snyk Team, DeepSource, Qlty and SonarQube Cloud, all of which take a card and provision immediately. Direct enterprise sales covers everything else: Coverity (now Black Duck), Checkmarx, Fortify, Veracode, Klocwork and Helix QAC (Perforce), Parasoft and PVS-Studio are all quote-only with no published list price. Cloud marketplaces are the third route and the one procurement teams forget: AWS Marketplace, Azure Marketplace and Google Cloud Marketplace carry several of these vendors, which lets the spend draw down an existing committed cloud spend agreement and skips a separate vendor onboarding.
How do I get a quote for static code analysis software?
Bring four numbers to the first call and you will get a real price instead of a discovery sequence: total lines of code to be analysed, number of contributing developers who commit in a 90-day window, number of private repositories, and your deployment requirement (cloud, self-hosted, or air-gapped). Those four map onto every pricing unit in this market. Ask three questions explicitly: what is the renewal uplift cap, what happens when we exceed the LOC or contributor band mid-term, and is the self-hosted price the same as the cloud price. Only three vendors across the wider code review market publish an enterprise rate card at all, so expect negotiation and expect the first quote to be a list anchor.
Static code analysis software prices
Verified at source on 2026-10-18: Codacy Team $18 per developer per month billed yearly ($21 monthly, capped at 30 developers), Developer tier free. Semgrep Teams $30 per contributor per month for Code, $30 for Supply Chain, $15 for Secrets; Free tier capped at 10 contributors and 10 private repositories. Qlty Pro $20 per contributor per month, Enterprise $30, Free tier with 1,000 analysis minutes per month. DeepSource Team $24 per user per month billed yearly, plus AI review at $8 per 10K LOC. Snyk Team from $25 per month with 100 projects and 1,000 Snyk Code tests. SonarQube Cloud Team from $34 per month for up to 100k LOC, free up to 50k LOC on private projects. SonarQube Server, Coverity, Checkmarx, Fortify, Veracode, Klocwork, Helix QAC, Parasoft and PVS-Studio publish no list prices.
Static analysis tools for a large codebase
Above roughly a million lines, three constraints decide the choice and none of them is detection quality. First, incremental analysis: a tool that rescans everything on every pull request will take longer than your developers will wait, so you need diff-scoped analysis with a baseline. Second, the pricing unit: per-LOC pricing (SonarQube) scales with the codebase while per-contributor pricing (Semgrep, Codacy, Qlty) scales with the team, and on a large old codebase with a small team those two produce very different bills. Third, monorepo handling: ask explicitly whether the tool can scope rulesets per directory and run only the affected projects. SonarQube Data Center Edition exists specifically for horizontal scaling at this size.
Which static analysis tools are genuinely free for open source?
Verified 2026-10-18: SonarQube Cloud is free for public projects, DeepSource is free for public repositories with 1,000 pull request reviews per month, Codacy is free forever for open-source projects, Semgrep CE is LGPL-2.1 and free for any use, and PVS-Studio advertises free licences for open source projects, students and Microsoft MVPs. CodeQL is free on public repositories through GitHub code scanning. Cppcheck is GPL-licensed and free, as are clang-tidy, the Clang Static Analyzer, SpotBugs, PMD, Checkstyle and Error Prone. The open source tier of this market is unusually strong, which is why the paid tier concentrates on interfile taint analysis, governance and reporting rather than on basic defect detection.
Can static analysis block a pull request from merging?
Yes, and whether a specific tier can is the question most buyers forget to ask. SonarQube Community Build cannot: it analyses the main branch only and cannot analyse pull requests, so the gate starts at Developer Edition. SonarQube Cloud's free tier does include pull request analysis, up to 50k LOC on private projects, which makes it a genuinely different product from the self-hosted free edition despite the shared name. Codacy, DeepSource, Semgrep, Snyk and Qlty all post a status check that can be marked required in GitHub branch protection. Always scope the gate to new code on the diff, not to the whole repository, or the gate becomes an override button.
