Vigil – Lightweight Linux server monitoring that runs on Cloudflare Workers
I got tired of either paying per-host for hosted monitoring or standing up a Prometheus/Grafana/node_exporter stack just to watch a handful of small servers. So I built Vigil.
The idea: you don't run any monitoring infrastructure yourself. The backend is a Cloudflare Worker with D1 for storage and KV for state, plus a 1-minute cron for alerting. So it scales to zero and costs nothing on the free tier for a small fleet. The agent is a single Python file using only the stdlib (no pip install), managed by systemd. The dashboard is a React SPA on Cloudflare Pages.
