Library Picker
Picks the right UI or animation library for the job.
What it does
Pick the right library for a given frontend task from a curated, opinionated list, numbers, OTP inputs, charts, command menus, virtualization, drag and drop, toasts, state, styling, and more. Only runs when explicitly invoked; it does not trigger on its own.
Install in under a minute
