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.
Hey Product Hunt!!! I’m Malo, co-founder of heal.dev.
The problem:
👉 Code review and static analysis often miss real runtime bugs and vulnerabilities.
👉 Even with top-performing coding agents, we still ship bugs and vulnerabilities to production. We’ve seen that firsthand by running Heal on a collection of open-source repositories: https://www.heal.dev/#sandboxes.
The solution
👉 Instead of just scanning your code, Heal spins up a production-like sandbox with your external dependencies mocked.
👉 Heal finds bugs, perf issues, and vulnerabilities at runtime. It reproduces each against the sandbox before reporting.
👉 Unlike asking a coding agent to write end-to-end tests, Heal proactively hunts for edge cases and runs exploratory testing, not just the happy path.
The key difference
👉 Review bots find what a developer would change to keep code clean. A lot of findings.
👉 Heal finds a proven user behaviour that causes a bug. Fewer findings, closer to the user.
With Heal, you get high-signal, verified bugs and vulnerabilities users would see, and a completely autonomous system. It's free during the beta, no cc required: www.heal.dev
Debate club 🥊 Ding ding ding!
One question for y'all: what makes it so that you don't auto-merge all PRs? Could Heal be the reason you finally do?
