MonitorFlare
Zero-cost self-hosted website monitoring and public status page running on Cloudflare Workers.
Webfree

MonitorFlare is a self-hosted uptime-monitoring platform with a public status page that runs entirely on Cloudflare's free tier (Workers, D1, and Pages). It checks HTTP/HTTPS, DNS, and TCP-port targets, tracks SSL certificate and domain expiry, and escalates alerts on error-rate thresholds or consecutive failures. Built as an enhanced fork of Uptime-Monitor, it targets developers who want free monitoring without running their own servers.
