Building UI components is often tedious work. OpenUI aims to make this process fun, quick, and flexible. This is the tool we use at W&B to test and prototype the next generation of tools, built on top of LLMs to create powerful applications. You can describe your UI with imagination, and then see the rendering effect in real time. You can request changes, and convert HTML to React, Svelte, Web Components, and more. Think of it as an open-source and less polished version of a V0.
