About uizr.dev

uizr.dev is an index of frontend and UI tooling for working engineers: React UI libraries, animation primitives, design systems, CSS tools, agent tooling, editors, and build systems.

This is not a review site. There are no star ratings, badges, or synthetic benchmarks. It is not a feed of everything that shipped this week; most libraries do not need an entry. A tool appears here when it solves a concrete problem in a distinct way, or introduces an architecture worth studying.

I built it because tracking frontend tooling means wading through marketing copy, rewritten docs, and noisy timelines. The point here is technical signal without the noise.
