Integrations

Connect Muster to the LLM frameworks, model providers, gateways, and tools you already use — 100+ integrations covered.

Muster is built on top of the open-source Langfuse core, which means it speaks the same OpenTelemetry-based ingestion API and works with the same SDKs and integrations the wider Langfuse ecosystem supports. If your stack already emits traces to Langfuse, pointing them at Muster takes a host swap and an API key — nothing else changes.

You can instrument your application in three ways:

  1. Native SDKs — install the langfuse Python or JS/TS package and either wrap your LLM calls with the provided decorators / clients, or push spans manually. This is the path with the richest tooling (prompt management, evaluations, datasets) and works against any model provider.
  2. OpenTelemetry endpoint — point any OTel-compatible tracer (Java, Go, Rust, .NET, etc.) at the Muster OTLP endpoint and your spans show up as traces. Use this when there is no first-party SDK for your runtime.
  3. Drop-in framework integrations — frameworks like LangChain, LlamaIndex, the Vercel AI SDK, or LiteLLM ship Muster/Langfuse callbacks out of the box. Wire the callback once and every call routed through the framework is captured automatically.

The pages below cover every integration grouped by category. Pick the one that matches what you're already using; if you don't see a fit, the OpenTelemetry path covers everything else.
