HTTP status and response time, keyword and JSON assertions, TCP ports, ICMP ping, DNS records, and push heartbeats for cron jobs and workers.
Uptime monitoring and status pages
Host Status checks your websites, APIs and servers from independent agents, alerts the right people on the channels they already use, and keeps your users informed with a public status page.
Free plan available. No credit card required.
Multi-location
Every monitor runs from several locations at once. Outages are confirmed before anyone is paged, and if a location goes dark, the others take over.
A monitor is marked down only when locations agree. One network blip never wakes you up.
If an agent or a whole location fails, its checks move to the others within seconds.
Several cores share the work, so there is no single point of failure between a check and your alert.
Product
A focused tool: reliable checks, alerts people trust, and a clear page to point your users to.
HTTP status and response time, keyword and JSON assertions, TCP ports, ICMP ping, DNS records, and push heartbeats for cron jobs and workers.
Retries before alerting, re-notify every N failures, and quiet hours during planned maintenance.
Group monitors, publish incidents and show 90 days of availability. JSON endpoint and SVG badges included.
Get warned days before a TLS certificate expires. Schedule one-off or weekly maintenance windows in any time zone.
Owners, admins and read-only members. Several workspaces per user, two-factor authentication and API keys.
How it works
Paste a URL, host or port, pick the interval and what counts as healthy. Tags keep large setups tidy.
Lightweight agents lease due checks from the core, so no check runs twice and a failing node never stops monitoring.
When a check fails after retries, the right channels are notified once, and your status page updates on its own.
Notifications
Secrets are stored server-side and never sent back to the browser. Webhooks are signed with HMAC.

FAQ
Websites and APIs over HTTP(S), with keyword or JSON checks, TCP ports, hosts via ping, DNS records, and anything that can call a URL through push monitors, such as cron jobs and queue workers.
As often as every 20 seconds, depending on your plan. Each monitor has its own interval, timeout and retry settings.
A monitor is only marked down after the retries you configure fail. You can also mark maintenance windows, during which no alerts are sent.
Every workspace can publish status pages with grouped monitors, incidents, uptime history and its own language. There is a JSON endpoint and SVG badges for your README.
Yes. Create API keys with admin or read-only access and manage monitors, status pages and more over a REST API.
Its checks move to the other locations automatically, usually within seconds, and you are not alerted for it. A monitor is only marked down when the remaining locations confirm the failure.
Yes. Paid plans can be cancelled at any time and stay active until the end of the billing period.
