Reviewer scorecard
“Clean UI, open source, and supports every protocol. The git-based sync is useful for teams.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Lighter than Postman and open source. For most API development needs, it's the right balance of features.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Functional but the UI isn't remarkable. It gets the job done without inspiring joy.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
