+
+[Baselime](https://baselime.io/) is an observability solution built for modern cloud-native environments. It combines logs, metrics, and distributed traces to give you full visibility across your microservices at scale.
+
+This integration allows you to connect to a Baselime environment from your Worker to automatically send errors and logs to Baselime with no code changes needed in the Workers application.
+
+:::note
+
+
+Baselime integration is available to all Enterprise customers and Free, Pro, and Business customers on the [Workers Paid plan](/workers/platform/pricing/).
+
+
+:::
+
+## How it works
+
+This integration adds a [Tail Worker](/workers/observability/logging/tail-workers) to your application Worker. The Tail Worker automatically sends errors and uncaught exceptions to the Baselime environment you have configured.
+
+This integration supports the following Baselime features:
+
+* **[Logging](https://baselime.io/docs/analysing-data/overview/)**: Request info, logs, and exceptions are all available to be searched for and analyzed.
+* **[Error tracking](https://baselime.io/docs/analysing-data/errors/)**: Actively find and be notified of new errors and track their resolution.
+
+:::note
+
+If there are more configuration options that you would like to see, leave us feedback on the [Cloudflare Developer Discord](https://discord.cloudflare.com) (channel name: integrations).
+:::
+
+## Set up an integration with Baselime
+
+To set up an integration with Baselime, you need to have a Baselime environment to connect to. If this is your first time using Baselime, you will be prompted to create an account and an environment during the integration setup.
+
+To add the Baselime integration to your Worker:
+
+1. Log in to the [Cloudflare dashboard](https://dash.cloudflare.com) and select your account.
+2. Select **Workers & Pages**.
+3. In **Overview**, select your Worker.
+4. Select **Integrations** > **Baselime**.
+5. Follow the setup flow.
+
+Once installed, the integration will automatically start forwarding events to Baselime. To learn more about Baselime, refer to [Baselime's official documentation](https://baselime.io/docs/).
