heal.dev
Tests apps in production-like sandboxes and reproduces bugs, performance regressions and vulnerabilities.
Product brief
What heal.dev does.
Code review catches what’s wrong in a diff. Heal catches what breaks when the app runs. Heal learns how to run your application, builds a production-like sandbox with external services stubbed, then hunts for bugs, performance regressions, and runtime vulnerabilities users would hit. It reproduces every defect before reporting it, so you get real bugs to fix, not a backlog of AI-generated suspicions.
