The Only Uptime Monitor That Covers Everything

The free plan includes 15 monitors with 7 monitor types (HTTP, Ping, SSL, Domain Expiry, Security Headers, Mixed Content, and Multi-step API Transactions), 5-minute check intervals, and email alerts. It is free forever with no credit card required.

We support 26 monitor types: HTTP, Ping, SSL Certificate, Domain Expiry, Security Headers, Mixed Content, Port, DNS, Heartbeat, Content Change, Blacklist, SMTP, WebSocket, Broken Links, GraphQL, Sitemap, Lighthouse, JSON API, Redirect Chain, WHOIS Change, FTP, IMAP, POP3, Multi-Step, Screenshot, and Browser Transaction.

We use two layers of verification. For multi-region monitors, every check runs from 5 global locations with majority-vote consensus — your site is only flagged as down when 3+ regions agree. For single-region monitors, every failure triggers an automatic confirmation recheck 30 seconds later. Only confirmed failures create alerts. Zero false alarms from network hiccups, DNS glitches, or temporary blips.

With our Business and Agency plans, checks run every 30 seconds. Combined with instant alert delivery to 10 channels (including Slack, PagerDuty, Jira, and SMS), you can be notified within seconds of an outage.

Private Workers are open-source agents you install inside your own network to monitor internal services (databases, internal APIs, intranet sites) that are not accessible from the public internet. They require no inbound firewall rules — they poll our API for jobs and report results back.
