The $2M race condition other tools missed

Three senior engineers approved this PR. Two AI tools missed it. PR Buddy caught it in 28 seconds. See the exact vulnerability and fix.

// ❌ Vulnerable Code - Race Condition

FAQ

ESLint and SonarQube use regex patterns and static rules. PR Buddy uses AI to understand code semantics and context, catching vulnerabilities that rule-based tools miss. It also integrates natively with GitHub PRs instead of requiring CI/CD setup.

No. PR Buddy fetches code via GitHub API, analyzes it in memory, and discards it immediately. We never store your source code. All analysis happens in real-time during the PR review.

PR Buddy supports JavaScript, TypeScript, Python, Go, Java, Ruby, PHP, and C#. We're constantly adding support for more languages based on user feedback.

Yes! Pro and Team plans include a .prbuddy config file where you can define custom rules, naming conventions, architecture patterns, and test coverage requirements specific to your team.

Yes! All paid plans come with a 14-day free trial. No credit card required. The Free plan is available forever with limited features.
