Reviewer scorecard
“EAS Build, OTA updates, and the managed workflow eliminate the worst parts of mobile development. Indispensable.”
“Best open-source LLM observability. Traces, prompt versioning, and evals in one tool. Self-hosting option is a must.”
“Expo has matured from toy to production platform. The config plugins and custom dev clients removed the old limitations.”
“Open source means no vendor lock-in. The tracing UI is clean and the integration with LangChain and Vercel AI SDK is seamless.”
“Expo is making React Native the default for mobile. Universal apps (web + mobile) from one codebase is the future.”
“LLM observability is becoming as essential as APM. Langfuse is the Grafana of AI — open source and community-driven.”
