Built-in interactive API reference for self-hosted deployments

Tobias Wochinger

Explore and test the API directly from your Langfuse deployment, including air-gapped installations.

Self-hosted Langfuse deployments now include an interactive API reference at /api/docs. It renders the OpenAPI specification bundled with your running deployment, so it also works in air-gapped environments.

You can use it to:

• Explore available endpoints without switching to an external API reference.
• Test requests against your deployment directly from the browser.
• Generate clients and validate integrations using the OpenAPI YAML at /api/openapi.yaml.

The existing /generated/api/openapi.yml endpoint remains available. See the self-hosting FAQ for details.
