Get notified when your Workers builds succeed or fail

QueuesCloudflare · Developer platform

You can now receive notifications when your Workers' builds start, succeed, fail, or get cancelled using Event Subscriptions.

Workers Builds publishes events to a Queue that your Worker can read messages from, and then send notifications wherever you need — Slack, Discord, email, or any webhook endpoint.

You can deploy this Worker to your own Cloudflare account to send build notifications to Slack:

The template includes:

  • Build status with Preview/Live URLs for successful deployments
  • Inline error messages for failed builds
  • Branch, commit hash, and author name

For setup instructions, refer to the template README or the Event Subscriptions documentation.
