Runs your app in a sandbox to find bugs and security issues, each with a failing test

heal is a tool that hunts for bugs in software. Instead of only reading code changes like a code reviewer, it runs your product in a sandbox that replicates production. It looks for reproducible bugs, runtime vulnerabilities and performance issues. The site is copyrighted by MYIA SAS (heal.dev).

You connect GitHub and get a report. It runs locally or in the cloud. Heal reads your code for suspicions, then tests each one against the sandbox. It only files what a test reproduces. Each defect comes with its steps and the failing test that proves it. The page also shows a coding agent being asked to fix a defect. There's a free trial with no credit card required, and the page says it's free for open source projects.
