- [meta/lexical](https://seerepo.com/r/meta/lexical): Lexical is an extensible text editor framework that provides excellent reliability, accessibility and performance.
- [shadcn-ui/ui](https://seerepo.com/r/shadcn-ui/ui): Composable, accessible components with thoughtful defaults. Build your own component library with code you can customize, extend, and make your own.
