Integrations

Flowise

Native Muster integration in Flowise — drag-and-drop LLM flows with full observability.

Flowise is a drag-and-drop, no-code platform for building custom LLM applications. The native Muster (langfuse) integration captures runs across the UI, API, and embed deployments.

Setup

1. Get Muster API keys

2. Install and launch Flowise

npm install -g flowise
npx flowise start

3. Connect Muster

In Flowise's analytics settings, add your Muster credentials:

LANGFUSE_PUBLIC_KEY
LANGFUSE_SECRET_KEY
LANGFUSE_HOST — https://app.getmuster.io (or your self-hosted URL)

Optionally set a release value to version-tag your flows.

4. Session tracking

Flowise's chatId is automatically mapped to Muster's sessionId (requires Flowise 1.4.10+). To attach a userId per request, pass it through overrideConfig:

{
  "question": "your prompt",
  "overrideConfig": {
    "analytics": {
      "langFuse": {
        "userId": "user1"
      }
    }
  }
}
