✔UptimeFlare

A more advanced, serverless, and free uptime monitoring & status page solution, powered by Cloudflare Workers, complete with a user-friendly interface.

This is a fork of lyc8503/UptimeFlare, used for monitoring waynecommand.com services.

📢 [SECURITY ADVISORY 2026/03/04] A vulnerability (CVE-2026-29779) that could expose monitor configuration and credentials in uptime.config.ts to clients was fixed. Versions between 2025-09-21 and 2026-03-04 are affected. Affected users are strongly advised to upgrade to the latest version.

🎉 [UPDATE 2026/01/03] UptimeFlare has been migrated from KV to D1 Database. The Terraform Cloudflare provider is updated to v5 and the data structure has been optimized for better performance.
