 "page_title": "How to version and test prompts outside your code with Langfuse",
 "summary": "Move prompts into Langfuse Prompt Management and iterate on them in the LLM Playground.",
 "who": "A product team where prompt changes need a code deploy and nobody knows which version is live.",
 "problem": "Prompts hard-coded in the app are slow to change and impossible to compare.",
 "outcome": "Versioned prompts fetched at runtime, with a playground for trying changes against real traces.",
 "steps": [
  "Run Langfuse self-hosted or on Langfuse Cloud",
  "Create your prompts in Prompt Management and fetch them from the SDK; caching on server and client keeps latency low",
  "When a trace shows a bad result, open it in the LLM Playground and try a prompt or model change",
  "Publish the better version and compare results over time"
 ],
 "agent_prompt": "Using langfuse/langfuse, move the prompts in <file> into Prompt Management, update my code to fetch them through the SDK, and set up the playground so I can test a new version against <example trace>.",

 "requirements": [
  "Docker and Docker Compose for local self-hosting, or a Langfuse Cloud account",
  "The Python or JS/TS SDK, or a supported framework integration",
  "For production: a VM, Kubernetes with Helm, or Terraform on AWS, Azure or GCP"
