Website Uptime Checker

Run an on-demand HTTPS availability check. See status, response time, redirects, and TLS hints from a real request.

How to use

  1. Enter a public HTTPS URL.
  2. Run Check. Review status, timing, and redirects.
  3. Optionally keep a local history in this browser to compute a simple uptime percentage.

Examples

  • Marketing site

    Check https://example.com after a deploy to confirm a 200 and measure response time from this region.

  • Redirecting apex

    See the redirect chain when a root domain sends visitors to www.

Public HTTPS only, SSRF-protected, rate limited. No background jobs or email incidents unless you enable browser notifications on this device. Local history never leaves the browser.

FAQ

Is this real uptime monitoring?
Each run is a live request. A percentage is shown only if this browser already stored earlier samples for that URL. It is not a multi-region SLA.
Do you store my URLs on a server?
No. Optional history uses localStorage. Checks are not scheduled in the cloud in this version.
