Founded
2008Sonar builds code quality and security analysis products for development teams across server, cloud, and IDE deployments.
Sonar's core platform is the SonarQube product family, spanning SonarQube Cloud (SaaS), SonarQube Server (self-managed), SonarQube for IDE (a free extension), the Advanced Security add-on for SAST and SCA, and Gitar for AI code review. Enterprise tiers cover more than 40 programming languages with integrations for GitHub, Bitbucket, Azure DevOps, and GitLab.
The platform centers on Quality Gates, AI CodeFix one-click remediation, and continuous code verification across the development workflow. As of 2022, Sonar reported its tools were used by more than 7 million developers and 75% of the Fortune 100.
Sonar positions its platform as the trust and verification layer for AI-written code, extending from human-written code review into the agentic development cycle. Its 2022 investment was aimed at reaching $1 billion in revenue and public-market readiness, targeting an addressable audience of roughly 70 million developers.
As of 2022 the company reported more than 7 million developers using its tools and over 750 billion lines of code analyzed daily, with an APAC headquarters opened in Singapore. Its 2026 agentic expansion includes the Hunter Agent, Sonar Agent Essentials, an open-source MCP Server, and the SonarQube CLI.
Sonar combines code quality and security verification in one deterministic platform, distinguishing it from single-dimension tools that address only one of the two. Its open-source roots, including a free Community Build, a free IDE extension, and a free cloud tier, drive bottom-up adoption among developers.
Its customer base includes Snowflake, Booking.com, Deutsche Bank, AstraZeneca, and Ford. As of 2026, company materials cite a leadership position in the Gartner Magic Quadrant for the category and a G2 Leader rating for six consecutive years at 4.6 out of 5.
Sonar uses a freemium, lines-of-code-based model: a free tier covers up to 50,000 private lines of code, and the Team plan starts at about $34 per month as shown on the current pricing page. Enterprise pricing is custom annual, and SonarQube Server is sold per instance per year by edition.
Server editions (Developer, Enterprise, Data Center) scale by analyzed LOC, while Gitar is priced per user at roughly $20-25 for Core and $40-50 for Pro with a free open-source plan. Agentic add-ons are usage-based or custom on Team and Enterprise tiers, and a 14-day trial is offered.
