About
About Fixter.
Fixter catches the errors and bugs in your app in production, finds the root cause, and fixes them: in your coding agent over MCP, or as a pull request ready for your review. Error tracking, logs and uptime monitoring for small teams.
Fixter here means the monitoring platform at fixter.dev, built by a small team in Estonia.
Who builds it
Product leader at Bolt, where she watched 20% of her engineering resource go into debugging issues instead of building.

Ran a payments system moving over €1B a year at EasyPark, where the hard part was never the fix but finding what actually broke.
