Description

Deploys a self-hosted Langfuse instance for tracing LLM calls, tracking token costs, and evaluating model output. If you're building with LLMs and want to see what your models are doing in production, this is the observability layer.

Installs a single Helm release in the langfuse namespace with Postgres, ClickHouse, Redis (Valkey), and MinIO bundled as sub-charts -- no other blueprints needed. Your application's LLM SDK connects to the webUrl output to send traces. The webHost and webPort outputs let other installations reference Langfuse's internal API.

Enable "Expose Dashboard" to publish the Langfuse UI at <installation-name>.<environment-domain> with auto-provisioned TLS. Disable signup to restrict access to existing users only.
