Base UI vs. Tailwind CSS vs. Untitled UI vs. python-sql Comparison Chart

​Base UI is a library of headless ("unstyled") React components and low-level hooks, offering developers complete control over their application's CSS and accessibility features. Extracted from Material UI, these components are now available as a standalone package, providing the same robust engineering without implementing Material Design. Base UI includes prebuilt components with production-ready functionality and low-level hooks for transferring that functionality to other components. With Base UI, developers can rapidly build on top of foundational components using any styling solution they choose, no needing to override any default style engine or theme. It abstracts away aspects of UI development like accessibility, cross-browser compatibility, and event handling, allowing developers to focus on design implementation. Base UI's skeletal components give a sturdy foundation to apply custom styles with ease, supporting styling methods such as vanilla CSS, Tailwind CSS, etc.
