### What we like

Drop-in library to help with React performance debugging. Requires no code changes - works from a script tag, via npm or as a CLI. Supports Next.js and Vite. Enhances the capabilities of React Devtools (it’s not a replacement).

### Tradeoffs

React Native and a Chrome extension are on the roadmap. Also, consider whether React is the right tool. Templ + htmx are worth playing with!
