Error monitoring for apps is now generally available on Retool Cloud. It will be available in Self-hosted Retool 3.114 Edge and a subsequent stable release.
You can set up integrations with Datadog and Sentry. With these integrations, app errors are reported with a callstack and descriptive tags when you view and interact with an app in preview or public (end-user) mode.
To connect third-party observability providers, you can report app errors using Retool Events and build a workflow that triggers whenever an app error occurs and automatically notifies your observability provider.
