Monitoring 47 endpoints across 2 developers

Everything you need. Nothing you don't.

Auto-Discovery

Enter your domain โ€” we crawl your sitemap, probe common paths, and find every endpoint worth monitoring. One click to monitor them all.

4-Region Consensus

Every check runs from 4 regions. Majority vote + 2-consecutive-failure confirmation means no false alarms. When it recovers, you know instantly.

Cron & Heartbeat

Unique ping URL for your scheduled jobs. If your cron misses its window, you'll know immediately.

JSON/API Assertions

Assert on response fields with dot-path selectors. Catch broken APIs that return 200 with bad data.

SSL Expiry Alerts

Get warned before your cert expires. Catches mismatched domains and broken chains too.

Email, Slack, SMS & Webhooks

Get alerted the way you work. Every channel included free โ€” no paywalls.

Public Status Pages

Share a clean status page with your users โ€” 90-day history, live status, incident log. Custom branding included.

Full REST API

Create monitors, pull check data, automate your workflow. Wire it into CI/CD. Free on every plan.
