wemutate — know your code actually works

the problem

A tsunami of code slop.

AI writes code faster than ever — but who checks it? There's too much code to review by hand, so companies face a bad choice: ship untested code or delay the release. And asking AI to review AI doesn't work — it gives itself full marks.

why it's different

Make your tests independent from AI.

AI review tools get it wrong. wemutate proves your tests catch real bugs.

AI-native: drops into Claude Code, GitHub and your CI
Add a quality-gate to ensure AI code tests are independently verified
Share with others your testing progress, but your code stays private

the survivor — the bug your tests didn't catch. we find it before your users do.

how it works

We break your code on purpose.

wemutate plants small, deliberate bugs — mutants — into a copy of your code, then runs your tests. Good tests kill the mutants. Survivors show exactly where a real bug would slip straight through to production.

Mutate. We generate hundreds of realistic bugs across your codebase — Java, JS/TS, Python, C/C++ — using the proven gold standard for code testing, with 18 years of experience behind it.

Verify. Your test suite runs against every mutant. This is independent of AI — separate, mathematical, rigorous. Not marking its own homework.

Ship. You get a clear report of what your tests actually protect. This approach prevents ~70% of bugs reaching production (Google study, 2021) — so you can release with confidence, faster.
