We trained Apex for React Native. It landed #2 at fixing web React. Callstack's Apex is tied #5 overall on @aidenybai's ReactBench. React Native tuning carries over to the web. Try it on Vercel AI Gateway or apex.callstack.com

If you're a React dev: - GPT 5.6 Sol xhigh performs the overall the best - GPT 5.6 Terra medium is the most bang for your buck Claude Fable 5 performs on par with Sol but is on average 6x more expensive!

react.doctor rules are now in the React, Next.js and TanStack presets for ESLint and Oxlint! The useful stuff: fewer unnecessary effects, better render performance checks, hydration catches, server component rules, security checks and framework-specific diagnostics. Thanks a million, @milliondotjs 🙌
Code snippet displays ESLint rules for React with error settings for various state management and rendering issues in a TypeScript format.
