UpAlert is free website uptime monitoring that checks your sites every minute and sends instant alerts via email or Slack when something breaks.
Simple, powerful uptime monitoring — without the complexity.
Checks as often as every minute on Pro, so you find out about downtime fast — every minute matters when users can't reach your app.
Email and Slack notifications the moment your site goes down — and again when it recovers.
Track uptime % over 24h, 7 days, and 30 days. Response time trends so you can catch slowdowns early.
Share a beautiful status page with your users and customers. Build trust by being transparent.
Runs on Cloudflare's global edge network — no servers to manage and no agents to install.
Automatic incident detection and resolution tracking. Full outage timeline with root cause notes.
