About DeepSource

DeepSource combines 5,000-plus deterministic static analysis rules across 30-plus languages with an AI review agent that runs on every pull request, positioning itself as a genuine SonarQube and CodeRabbit hybrid rather than choosing one approach. On the independent OpenSSF CVE benchmark testing real-world vulnerability detection, DeepSource topped the leaderboard at an 84.51% F1 score, ahead of Cursor BugBot, Devin Review, and other major competitors. Pricing is transparent at $24 per user per month on annual billing ($30 monthly), including a $100 annual AI-review credit per user, with no lines-of-code-based pricing surprises the way SonarQube has. Setup is measured in minutes rather than the days typically required for SonarQube, and the free tier covers up to 1,000 PR reviews per month for open-source projects.
