Zero-Cost Uptime Monitoring + Status Page on Cloudflare's Free Tier

Monitoring your websites shouldn't cost money or require a VPS. Most uptime tools need a server, a database, or a paid plan — even small hobby projects end up with a $5/mo bill just to check if a site is up.

MonitorFlare is a self-hosted uptime monitoring platform with a beautiful public status page that runs entirely on Cloudflare's free tier: Workers + D1 + Pages. No server, no VPS, no monthly costs — and it deploys in about 60 seconds with a one-click button.

It's an enhanced fork of Uptime-Monitor (MIT), with a Vue 3 frontend, PWA support, and i18n in 9 languages.
