EU-hosted uptime & cron monitoring(watchcat.io)

Watchcat is an EU-hosted uptime and cron monitoring service for developers and small teams. It checks your websites, APIs, and scheduled jobs, and alerts you when something fails so you can respond quickly.

It goes beyond simple uptime checks by tracking cron jobs and background tasks, helping you detect missed runs, delays, or silent failures. This makes it useful for automation-heavy workflows and internal systems.

Built with privacy and simplicity in mind, Watchcat keeps monitoring data within Europe and integrates with common channels like email, Slack, and Telegram.
