Enterprise License Key

All core Langfuse features and APIs are available in Langfuse OSS (MIT licensed) without any limits.

When running Langfuse self-hosted, you use the same deployment infrastructure as Langfuse Cloud. There are no scalability limitations between the different versions.

Some additional Enterprise features require a license key:

• Project-level RBAC Roles
• Protected Prompt Labels
• Data Retention Policies
• Audit Logs
• Server-Side Data Masking
• UI Customization
• Organization Creators
• Org Management API and SCIM
• Instance Management API

See pricing page for more details on Langfuse Enterprise.

Activating a License Key

After purchasing a license key, you can activate it by adding the following environment variable to your Langfuse deployment (both langfuse containers):

LANGFUSE_EE_LICENSE_KEY=<your-license-key>

Enterprise self-hosted deployments use limited telemetry for license compliance. See the telemetry documentation for the exact fields that are collected.
