UptimeFlare is a serverless uptime monitoring and status page solution that runs on Cloudflare Workers.
The tool addresses the need for free, easy-to-deploy uptime monitoring without requiring dedicated infrastructure.

The approach combines monitoring capabilities with a public-facing status page, allowing teams to track service health and communicate incidents to users from a single deployment.
Organizations should choose this tool if they want to avoid hosting costs and complex infrastructure setup while still gaining comprehensive monitoring. It suits projects of any size that need HTTP, HTTPS, or TCP port monitoring with up to 50 checks running at one-minute intervals. The tool supports customizable request methods, headers, and body content for HTTP checks, as well as custom status code and keyword validation. It maintains up to 90 days of uptime history and integrates with over 100 notification channels for downtime alerts. The status page includes interactive response time charts, scheduled maintenance alerts, incident history, and optional password protection. Users can deploy their own domain via CNAME and access real-time status data through a JSON API.
A security vulnerability affecting configuration exposure was identified and patched, with clear guidance provided to affected users.
