React Bits

React Bits is an open-source collection of more than 210 animated React components, backgrounds and text effects aimed at creative developers, with a paid Pro tier alongside the free library. Each component is driven by props, so a shader background like ColorBends can be tuned for colour, speed, noise and rotation in the docs before you copy it. With tens of thousands of GitHub stars, it is one of the larger sources of animated backgrounds for portfolios and landing pages.
