Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Web standards-first approach means your apps work without JavaScript. Loaders and actions are elegant patterns.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“The merge with React Router v7 is pragmatic. Web fundamentals and progressive enhancement are the right foundation.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“Merged into React Router. The ideas live on but the standalone framework identity is fading.”
