The static-analysis standard: 30+ languages, quality gates, clean-as-you-code.
SonarQube analyses source for bugs, vulnerabilities, code smells, duplication and coverage across more than thirty languages, and enforces a quality gate that can block a merge. Its clean-as-you-code model holds new and changed code to the standard while leaving legacy debt as a separate, deliberate decision. Available self-hosted (Community, Developer, Enterprise) or as SonarQube Cloud.
Best for
From €32 per year per 100k lines of code (Developer Edition, indicative)
Free tierFree tier: Community Build is free and self-hosted, covering the main languages without branch analysis.
What drives the bill: Licensed by lines of code, which makes cost predictable but expensive on large monorepos. Branch and PR analysis requires a paid edition.
