From "I'll set up monitoring later" to 50 paying customers

I got tired of spending hours configuring Prometheus + Grafana every time I needed basic server monitoring.

So I built CatOps — one curl command, 15 seconds, done.

curl -sfL https://get.catops.app/install.sh | bash

What you get: - CPU, memory, disk, network metrics - Auto-detection of services (postgres, redis, nginx, docker, etc.) - Alerts via Telegram/Email/Slack - Logs collection and search - AI assistant to analyze issues

Stack: Go agent (~50MB RAM), Python/FastAPI backend, ClickHouse for metrics, React frontend.

50 teams using it now. Free for 1 server.

https://catops.app

Feedback welcome - especially on what's missing for your use case.
