Catch problems with zero-config alerts

Automatic change notifications

Did you JavaScript bundle get bigger? Got a slow server response? Added a new image without an alt tag? Using a deprecated API? All of these can trigger an alert.

Zero-config, but configurable

Significant changes are detected automatically, without the need to set up thresholds. But if you need to you can fully customize the alerts.

Get front-end monitoring alerts where you need them

Send alerts by email, in Slack, or in Microsoft Teams.
