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!

I have used this for several personal assistant applications and it works amazingly. Obviously it is still restricted to the flaws of any model you are using it with, but the ability to constrain prompts is incredibly helpful (especially when it comes to getting things like JSON format from the AI).
