Create an AlertsDown monitorWhat this uptime & speed checker tests
This free uptime and speed checker gives you a fast, no-login "health snapshot" of any public website or endpoint. It follows redirects, reports HTTP status, and measures key performance timings like DNS, connect, TLS, TTFB, and total time. The website preview image helps you verify you’re looking at the right page.
- HTTP status and redirect count (with final URL)
- Response timing breakdown (TTFB / total + network phases)
- Remote IP + basic response metadata
- Live screenshot preview of the resolved page
Why downtime and slow responses matter
A site can be "up" but still effectively broken: slow DNS, slow TLS handshakes, or a bad backend can make pages time out. Speed issues impact SEO, conversions, and user trust. Use this snapshot to troubleshoot quickly before you set up monitoring.
How to use the tool
- Enter a hostname (e.g.
example.com) or full URL. - Click Run snapshot to fetch status + timings.
- Review the results and screenshot preview.
- Create an AlertsDown monitor to get email alerts when it goes down.
