Online tool

Check website availability online

See whether a public website responds, which HTTP status it returns, and where its redirects lead. The result is immediate and does not add the website to monitoring.

This is a one-time check: it does not create a monitor or send notifications.

Need continuous monitoring?

Put the website on uptime monitoring

UpChecker will check it on a schedule, keep status history, and send notifications when a real outage occurs.

What the check shows

HTTP response and redirects without account setup

Use the tool for a quick diagnosis after a deployment, domain move, or HTTPS configuration change.

Response status

Check whether the page returns a 2xx status, redirects visitors, or responds with an error.

Redirect chain

Review HTTP-to-HTTPS transitions and the final address after each allowed redirect.

Response time

Measure time to the server response without downloading arbitrary page content.
