Downtime Happens. The Question Is: Who Finds Out First?

If your users are the ones telling you the site is down, you've already lost their trust. Updown Monitor checks your website every 30 seconds from multiple locations and alerts you instantly when something goes wrong.

 

Everything You Need for Production Uptime Monitoring

Built for developers, agencies, and SaaS teams that can't afford downtime.

30-Second Check Intervals

Monitor intervals as fast as 30 seconds. Catch brief outages before traffic builds up or revenue is lost.

HTTP Methods & Status Codes

Support for HEAD, GET, POST, PUT, and PATCH. Validate any expected status code — from 200 to 404.

Authentication Support

Basic auth, custom headers, and bearer tokens. Monitor protected APIs and internal endpoints safely.

Response Validation

Validate response body text or headers. Alert when a specific string disappears or the payload changes.

Multi-Location Checks

Monitors run from multiple geographic regions. Detect regional outages that single-location tools miss.
