Get started

How it works

Three steps from an empty dashboard to checks that run on their own.

  1. Create your monitor

    Point Uptime at the URL, domain, port, or scheduled job you want to track.

  2. Choose how you're alerted

    Connect email, Slack, Discord, or a webhook. Set cooldowns to avoid alert fatigue.

  3. Watch the dashboard

    See uptime history, response times, and status update as checks run automatically.

Can I monitor authenticated API endpoints?

Can I check the response body, not just the status code?

Yes, with content checks for a keyword, phrase, or regex pattern.
