What platforms does Float UI support?

Float UI is available on Web App.

What are the limitations of Float UI?

No visual builder or theming system: every change happens by editing utility classes in code. The library is funded by sponsors and community effort, so component breadth and update cadence depend on that support. Site pages concentrate on components and templates, with little public documentation on versioning, accessibility or long term maintenance.

What is Float UI?

Float UI is a free, open source collection of Tailwind CSS UI components and React/Next.js website templates, offered for HTML, React, Vue and Svelte. Components are copied directly into your project and restyled with utility classes, making it a practical starting point for developers who want modern, responsive pages without a designer.

Float UI is an open source library of Tailwind CSS UI components and prebuilt website templates aimed at developers and founders who need to launch a polished product site without a dedicated design team. The collection covers the building blocks of a typical startup site, from team member lists and headers to full page templates, and everything is free to use. The project positions itself as a shortcut between an idea and a working interface: instead of designing each screen from scratch, you assemble pages from parts that already look modern and consistent. In practice the workflow is copy and paste. Each component is published with its markup, so you drop the code into your own project and adjust classes, colors and content to fit. Float UI ships the same components for plain HTML as well as React.js, Vue.js and Svelte.js, which means the library stays useful whether you are on a simple static page or a component-driven app. The templates are built on React and Next.js with Tailwind CSS, and the site claims they are fast, easy to use and well suited to search engines, so the output is meant to be production ready rather than a mockup. Responsiveness is handled at the component level: layouts are designed to hold up across screen sizes, which removes a lot of the manual breakpoint work that slows down small teams. Customizability comes from the Tailwind approach itself, since styles are expressed as utility classes you can edit in place. The project also points to MarsX as an environment where the same components can be used. Float UI sits in the same space as commercial Tailwind component marketplaces and paid template shops, but its open source, no cost model changes the tradeoffs. There is no license fee and no gated library, at the price of relying on community momentum and sponsor support. It best suits developers who are comfortable editing markup directly and who want a clean visual baseline more than a full design system with documentation, theming tools and support contracts.

How do you use Float UI?

1Browse the component library
Open the components page to see the available blocks. Each entry shows the rendered result next to its Tailwind markup, so you can judge both the look and the code before committing.
2Pick your framework variant
Choose HTML, React.js, Vue.js or Svelte.js for the component you want. The markup adjusts to the syntax of the framework you are already using in the project.
3Copy the component into your project
Copy the code block and paste it into the relevant file in your app. Because styles are Tailwind utility classes, the component inherits your existing Tailwind setup.
4Customize content and utilities
Replace placeholder text, images and links, then adjust color, spacing and typography classes to match your brand. Responsive breakpoints are already expressed in the markup and can be tuned.
5Add a website template
For a full starting point, take one of the professional templates built on React and Next.js with Tailwind CSS and adapt its sections rather than assembling every page from single components.
6Support the project or reuse in MarsX
If the library saves you time, the sponsors page explains how to back the project. Components can also be used inside MarsX if that is your build environment.
