SonarQube vs Semgrep

These two scanners meter your bill on different things, and that single choice shapes everything else. SonarQube counts lines of code in private projects, so a swollen monorepo costs more even when the team stays the same size. Semgrep counts contributors, meaning anyone who committed to a scanned private repository in the past 90 days, and then asks you to pick one product from Code, Supply Chain or Secrets. SonarQube ships a quality gate across 40+ languages, while Semgrep is a security engine under LGPL-2.1 whose rules you can read and rewrite. Both offer a free tier, though each stops at a different wall.

Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.

Where they differ

    The 50k-line door versus the 10-contributor door

    SonarQube Cloud's Developers plan is free forever for private projects up to 50k lines of code, with no card and no expiry. Semgrep's Free edition is free for up to 10 contributors and 10 private repositories, and it includes the Code and Supply Chain products. A solo developer with a big legacy codebase hits Sonar's wall first, because the meter counts lines. A twelve-person team with a tiny codebase hits Semgrep's wall first, because that meter counts people. Neither free tier is larger than the other, so which one suits you turns on whether you count lines or people, and this round is a tie.

    Depends on the buyer

  2. 02

    What a growing team pays on the paid plan

    SonarQube Cloud Team starts at $34 per month, billed monthly by card, for up to 100k lines of code, and the page positions it for teams under 50 developers. Semgrep Teams starts at $30 per month per contributor for Code (SAST) or Supply Chain, while Secrets is $15 per contributor per month. At a handful of developers Sonar's flat entry price looks lighter, since five Semgrep contributors on one product already come to $150 monthly. Semgrep's per-seat pricing is easier to predict from your headcount alone, but the lower starting figure goes to SonarQube.

    One product choice that Semgrep makes you repeat

    On Semgrep Teams you pick one product from Code, Supply Chain and Secrets, with up to 500 private repositories, and each product is billed separately. A team wanting code scanning and secrets detection therefore pays two rates for the same contributors. SonarQube's paid editions instead bundle branch and pull request analysis, software composition analysis, infrastructure-as-code scanning and governance. One exception applies: the Advanced Security add-on on Enterprise needs its own subscription, and the pricing page shows no figure for it. Sonar still bundles more per purchase, which is why this round goes to SonarQube.

    Running the engine without an account

    Semgrep's Community Edition is licensed LGPL-2.1, covers 30+ languages, and by default does not upload code when you run it locally. You can install the command line tool, point it at a repository and read findings with no account. SonarQube's Community Build is LGPL-3.0 as well, but the repository says branch and pull request analysis sit in the commercial editions. For a team that wants to scan a pull request in CI for free, the Semgrep route reaches that goal with fewer paid steps, so Semgrep takes the round. The saving is real but narrow, since it covers scanning only.

    Self-managed Server editions and their pricing

    SonarQube Server comes in Developer, Enterprise and Data Center editions, priced per instance per year by lines of code, and the pricing page we read shows no figures for them. Semgrep's hosted platform runs CI/CD deploys on its own infrastructure, and Enterprise is custom-priced with unlimited contributors, SSO and scale features. The Semgrep pages we read describe no self-hosted platform edition you can buy. If you must host the analysis yourself, only SonarQube lists that as a purchasable edition, although you will have to ask sales what it costs, since the page lists no prices for Server editions at all.

    Where each company says it sits

    SonarSource Sarl is a Swiss company with a registered UID, governed by Swiss law with arbitration in Geneva, according to its cloud terms. Semgrep, Inc. lists 799 Market Street in San Francisco in its privacy notice, while no country of establishment for the company shows up in the pages we read. That about page also reports a $100 million Series D led by Menlo Ventures. The SonarSource about page gives no seat or owners, yet the terms settle the jurisdiction on their own, and Geneva arbitration is a detail a buyer can cite. For a buyer who prefers a Swiss counterparty, the answer is clear.

When neither fits

Coverity is a further static analyser in our category worth a look if neither pricing unit suits you. If your priority is a cheaper entry point with a pull-request-first workflow, Codacy is the other candidate worth a trial. Both sit in the same category page, so you can compare their listed pricing next to these two before booking any demo.

SonarQube or Semgrep: questions

3 answers
Does an open-source repository change what SonarQube charges?

Only LOCs from private projects count toward the meter, according to the pricing page. SonarQube for OSS is free for public OSI-licensed repositories.

OSS maintainers also receive free access to paid-tier features, and SonarQube for IDE is always free. Private projects are where the bill comes from.

What exactly makes someone a Semgrep contributor for billing?

A contributor is anyone who committed to a private repository scanned in the past 90 days. That means a developer who stops committing eventually drops off the count.

The Free edition covers up to 10 of them, and Teams adds a cap of 500 private repositories. Enterprise is listed with unlimited contributors.

Can both tools be tried before paying?

SonarQube Cloud gives you 14 days of trial without a card on file, and its pricing page adds that Server can be trialled free as well.

Semgrep's route is the free engine on the command line. A banner on its home page also says Semgrep Guardian is free for 30 days. Both let you read findings before signing anything.
