License

You don't need a license key to install and start Sentinel — see Install with Docker to get running. Without one configured, Sentinel automatically runs on a 30-day trial.

Configuring your license key

Through the admin app: Admin → License, enter your key, Save.

Via environment variable:

LICENSE_KEY=your-license-key

License verification (call-home)

By default, Sentinel periodically verifies your license by contacting eu.altcha.org. As of version 1.15.0, this sends only minimal, non-telemetry details: application version, Node ID, and process ID.

Offline verification

If you need to avoid call-home entirely (e.g. an air-gapped deployment), use LICENSE_JSON instead of LICENSE_KEY — set it to the full contents of the license file attached to your purchase confirmation email:

LICENSE_JSON={"...": "..."}
