Lighthouse for Backend Code Quality
Get a health score. See how you rank. Track improvement over time. Know exactly what to fix to reach Top 5%.
Production Crashes You Never Saw Coming
Traditional linters catch syntax errors. We catch the behavioral issues that crash your app in production.
Missing Error Handling
42% of repos have unhandled promise rejections. One failed API call crashes your entire app.
await axios.get(url); // No try-catch 💥No Visibility
You don't know what you don't know. No way to measure code quality or compare to others.
Manual Review Doesn't Scale
Code review can't catch everything. Especially when using 3rd-party packages with complex error behaviors.
