Get notified when key text disappears or your API returns
the wrong data — before your users find out.
14-day free trial. No credit card needed during the trial.
Define exactly what a successful response looks like and get alerted when something breaks — even if your site still loads.
Define custom rules to validate the exact behavior of your website or API — like checking if a JSON key exists or if critical text is present. These assertions run at your chosen interval, so you’re the first to know when something silently breaks.
