Most website uptime monitors are built for developers and site owners — they require account setup, agent installation, or a paid subscription before you can check anything. WebsiteDown works differently: enter any domain and get a live server result in under three seconds, with no account and no cost.
What the free check covers
Every check on WebsiteDown runs a direct HTTP probe to the target server from our infrastructure. You get: whether the server is reachable, the HTTP status code returned, the response latency in milliseconds, and AI-powered outage intelligence from across the web.
The latency reading is useful beyond a simple up/down answer. A site that responds in 180ms is healthy. The same site responding in 3,800ms has a performance problem that will affect real users — even if it technically returns 200 OK.
Outage signals beyond the probe
A server probe tells you whether the site is reachable from one vantage point at one moment in time. That is useful but incomplete.
WebsiteDown layers two additional signals on top. Community reports show you how many people have reported problems in the last 15 minutes and 1 hour — a high report count suggests a widespread issue even if the probe succeeds. AI web intelligence scans social media and status pages for mentions of outages, errors, and degraded performance — surfacing information the HTTP probe cannot see.
Setting up ongoing monitoring
The free check is instant but manual. If you want to be alerted automatically when a site goes down, WebsiteDown's monitor feature checks your target every 60 seconds and sends alerts via email, Discord, or Telegram the moment it detects an outage.
The free plan supports one monitored site. Pro plans support unlimited sites with 60-second check intervals, multi-region probing, and Slack integration. You can set up monitoring from your dashboard after creating a free account.
Works for any site
WebsiteDown checks any publicly accessible domain — it is not limited to a list of tracked services. Enter your own site, a client's site, a competitor's site, or any API endpoint. As long as it resolves DNS and accepts HTTP connections, we can check it.
For domains that require authentication or return 403 to anonymous probes, the check will reflect that — which is expected behavior, not a false outage.
