Railo

About

Security scanners identify vulnerabilities, but your team remains responsible for resolving them. Railo bridges this divide by automatically generating and opening verified Fix Pull Requests for Python and TypeScript based on your open findings. It does not use LLMs or produce hallucinations. Instead, a deterministic AST engine combined with Z3 formal verification confirms the exploit path is removed prior to any PR creation. The service has already patched projects like HTTPie, with 34,000 stars, and BentoML, with 9,000 stars, in production. It offers a free plan, a Pro tier at $49 monthly, and a Team plan for $199 per month.
