I'm a developer and Code Genius is my pair programming, it's amazing how much time it already saved me. Especially when it comes to unit tests (Jest and React Testing Library) 💯 Recommended!

Really impressed with CodeThreat! It’s great to have a free tool that detects both code vulnerabilities and library risks. The setup was smooth, and it fits well into CI/CD pipelines. Definitely worth checking out!
