Reviewer scorecard
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Non-negotiable for any serious component library. Visual testing, docs, and interaction testing in one place.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Setup can be painful and builds are slow, but the alternative — no component isolation — is worse.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
“The best way to browse and understand a design system. Addons for accessibility and responsive testing are invaluable.”
