Bit.dev is a cloud-hosted collaborative platform for UI components extracted, modularized and reused with Bit. Web components have been around for a while, but building a modern front-end application by assembling small, independent components extracted from other projects has never been easy. Bit was designed to let you do exactly that: extract a component from an existing library or project. You can either build your own service on top of Bit for component collaboration or use Bit.dev.
