Reviewer scorecard
“EAS Build, OTA updates, and the managed workflow eliminate the worst parts of mobile development. Indispensable.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Expo has matured from toy to production platform. The config plugins and custom dev clients removed the old limitations.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Expo is making React Native the default for mobile. Universal apps (web + mobile) from one codebase is the future.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
