Know when shit hits the fan.
Fixter is APM and error tracking for teams that build with coding agents. It finds what breaks, works out why, and hands it to your agent over MCP.

We already know something's wrong. Before you do.

New issue. Customers are paying and not getting access. 23 users since Monday.
AI investigation: the Stripe webhook fails on subscription events, so the account never unlocks.

04 · who built it
We built the thing we kept wishing existed.
As a product leader at Bolt, I watched 20% of my engineering resource go into just debugging issues instead of building.

I ran a payments system moving over €1B a year at EasyPark. The hard part was never the fix, it was the hours of digging just to find what actually broke.

What is Fixter?
An AI native monitoring platform for small engineering teams: application performance monitoring, error tracking, and uptime monitoring in one place. It stores your logs, traces, and metrics, alerts you when something matters, and an AI agent investigates the root cause. You run it from your coding agent over MCP.
Do I need Claude Code?
No. Any MCP client works, Cursor and Codex included, and the setup prompt above works in all of them. Claude Code has a plugin that does the whole setup in one command. No agent at all? Four environment variables, standard OpenTelemetry.
Does Fixter access my code?
Monitoring and alerting never touch your code; they run on the telemetry you send. Investigations work on telemetry alone, and get sharper if you grant read access: the repository is cloned into a secure sandbox, used only for that problem, and deleted right after.
How does pricing work?
Free: 10 GB a month, forever, no card. Paid from €20 a month, pay-as-you-go or a bundle. The full breakdown, with what each plan includes, is on the pricing page.
I've never set up monitoring. Is this for me?
Yes, that is the point. If you can paste one prompt into your coding agent, it handles the rest. From then on, Fixter only speaks up when production needs you.
