Everything you need
A closer look at what you get, from the first check to the alert that reaches you.
Authenticated checks
Add Authorization headers to monitor endpoints behind auth.
Status code validation
Expect the exact status code your API should return.
Latency tracking
Watch P99 response time to catch slow-but-not-down degradation.
Content checks
Verify the response body contains an expected field or value.
How it works
Three steps from an empty dashboard to checks that run on their own.
Create your monitor
Point Uptime at the URL, DNS record, port, or scheduled job you want to track.
Choose how you're alerted
Connect email, Slack, Discord, or a webhook. Set cooldowns to avoid alert fatigue.
Watch the dashboard
See heatmaps, response times, and uptime history update as checks run automatically.
Frequently asked questions
The questions people ask most before they start monitoring.
Can I monitor authenticated API endpoints?
Yes — add custom headers, including Authorization tokens, to any monitor.
Can I check the response body, not just the status code?
Yes, with content checks for a keyword, phrase, or regex pattern.
