Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“The 'copy into your codebase' approach is genius. Full ownership, full customization, no version dependency hell.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Solved the component library problem by not being a library. The most practical approach to UI components.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“Beautiful defaults that look professional immediately. The theming system makes brand customization straightforward.”
