The anonymous checker on the homepage is free forever. Plans below add continuous monitoring of sites you own — starting at $4.99/mo.
Most uptime tools tell you that your site is down. Because we also run the public outage tracker for 850+ services, a monitor here can speak to why — whether yours is the only thing affected, or whether a provider it depends on is having an incident at the same time.
The free plan needs no credit card.
Yes — the free plan includes 1 monitor with 5-minute checks. Enough for a single personal site. Need more? Starter adds up to 5 with 60-second checks at $4.99/mo.
Yes, on every plan including Free. Switch on certificate expiry alerts for any monitor and we warn you once the TLS certificate is within 21 days of expiry. You get one alert per certificate, not a daily nag — renewing issues a new certificate, which resets it. It's opt-in per monitor rather than automatic, so a monitor pointed at a host you don't control doesn't nag you about someone else's certificate.
Yes, on every plan including Free. Alongside the status code you can assert on a JSONPath expression against a JSON body, a response header, or text anywhere in the body — and set the HTTP method, request headers, request body and basic auth. So "200 OK but the JSON says status: degraded" counts as down, which is usually the failure you actually care about.
Checking is one-off: you search for 'Discord' and see if it's down right now. Monitoring is continuous: we probe your site every 5 min (free) or every 60 seconds (paid) and email you when the status flips.
Partly — and you can try it free. Anyone can run a 5-region speed preview (US East, US West, EU/London, Tokyo, Hong Kong) on the speed-test page — a few checks a day, no account needed — to see reachability and round-trip latency from each region. Starter and Growth raise that daily limit and add the full regional reachability panel (DNS IP + latency divergence per region) for your own domains. The DNS/TCP/TLS/TTFB phase breakdown still runs from one serverless region for every check.
