baseui.sh is an open source component library and design language for building React product interfaces, focused on being restrained and accessible rather than heavily styled or opinionated. It is maintained as its own independent repository so that other applications can install it as a normal package dependency instead of copying interface code from a shared internal project. Installing it is done through a standard package manager, and using it involves wrapping an application in a provider component and importing individual pieces like buttons and cards, along with a separate stylesheet. The full set of components is available from the root of the package, but it also exposes narrower entry points grouped by category, such as actions, forms, and overlays, which makes it clearer where a given component comes from when importing it. Design tokens and icons, including a set of Phosphor icons, can also be imported on their own. The project documents a small set of design rules it follows consistently: every surface uses the same corner radius token except for shapes that are meant to be circular, a specific color is reserved only for primary actions and selection states, monospace type is reserved for code and technical values, and every interactive component is expected to support keyboard use, visible focus states, disabled states, and reduced motion preferences. Releases are managed with changesets, with the first version published by hand and later versions published automatically through GitHub Actions using npm's trusted publishing setup. The repository includes a documentation app, an example integration project, and standard open source files like contribution guidelines and a code of conduct. It is licensed under Apache-2.0, and its README notes that despite the similar name, it is not affiliated with the existing Base UI or Base Web projects.
