Keyword and content monitoring

Monitor what the page actually says

PageWarden reads the page body and checks that specific text is present, or absent. It is an uptime check that looks past the status code, so you catch a broken checkout, a leaked error string, or a defacement. On Hobby and up.

The PageWarden status board

Presence or absence

Assert text is there, or gone

Set a monitor to require that a page contains a phrase, such as Add to cart, or that it does not contain one, such as an error string. Either condition can mark the check down.

A page can return a healthy 200 and still be broken. Keyword monitoring reads the body, not just the response code.

Alerts when expected text goes missing, or bad text appears

What it catches

A broken page that still says 200

Catch a checkout that stopped rendering, a leaked stack trace, a missing call to action, or a defaced page, all while the status code looks fine.

When the text check fails, PageWarden opens one clean incident with the detail.
