Reviewer scorecard
“Hot reload, custom rendering engine, and Dart is surprisingly pleasant. Best for custom UI that needs pixel-perfect cross-platform.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Dart limits the developer pool. React Native with TypeScript/JavaScript has a much larger talent market.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Google's commitment level is uncertain given their track record. React Native has more ecosystem momentum.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
