Know the moment your site goes down.
Reliable uptime monitoring for websites, APIs, and services. Get pinged the second something breaks — by email or webhook.
50 monitors free, plus a 14-day Team trial on signup. No credit card required.
Everything you need to stay ahead of downtime
Built for builders and small teams who want monitoring that just works — without the per-monitor pricing tricks.
1-minute checks
Probe every endpoint as often as every minute. Catch outages before your users notice.
Multi-channel alerts
Email and generic webhooks. Route alerts to the channel your team actually watches.
HTTPS expiry alerts
Get warned weeks before a certificate expires — never get blindsided by a chain renewal.
AI assistant
Describe a monitor in plain English and the assistant builds it.
Team-ready
Invite teammates with role-based access so on-call sees only what they need.
Full check history
90 days of check results out of the box, with CSV export when audit season rolls around.
Up and running in two minutes

Pricing that doesn't punish you for shipping more
Start free, keep Solo for focused projects, and move to Team when on-call becomes a shared job. At $19/mo Team gives you 300 monitors, 50 seats, role-based access, and priority support — and every new workspace gets it free for 14 days.
