Uptime monitoring tools proactively check your website and APIs from multiple global locations, alerting you the moment something goes down.

Uptime Monitoring Features That Matter
| Feature | Why It Matters |
|---|
| Multi-Region Checks | A single location may report false downtime. At least 3 locations should agree before alerting. |
| SSL Certificate Monitoring | Expired SSL certificates cause "site not secure" errors. Monitor expiration with 30-day warnings. |
| Keyword Assertions | Check that the response body contains expected content — a 200 OK with an error page is still downtime. |
| Escalation Policies | If the primary on-call doesn't respond, automatically escalate to the next person after N minutes. |
| Maintenance Windows | Suppress alerts during planned maintenance to avoid false alarms. |
| Status Pages | Publicly communicate uptime and incidents to your users — builds trust. |
Decision Matrix
| Scenario | Best Tool | Why |
|---|
| Need status page + monitoring in one | Better Uptime | Best integrated status pages, modern UI |
| Enterprise, need global coverage (100+ locations) | Pingdom | Most check locations, transaction monitoring |
| Budget-constrained, many endpoints to monitor | UptimeRobot | 50 free monitors, cheapest paid plans |
| Browser-based testing (login flows, form submits) | Checkly | Playwright-based synthetic checks, best for browser |
| Simple health checks for side projects | UptimeRobot (free) | 50 free monitors, good enough for most projects |
Bottom line: Start with UptimeRobot's free tier — 50 monitors at 5-minute intervals is generous. Upgrade to Better Uptime when you need a status page and faster checks (3-min). Add Checkly when you need browser-based synthetic monitoring for critical user flows. Pingdom is the enterprise choice with the most global check locations.
