The short version

What is Metro UI?

Metro UI is a free, open-source front-end library for building responsive web apps. It ships 150+ ready components, nine helper modules and a built-in icon set, under the MIT license.

It is written and maintained by Serhii Pimenov, and the code lives on GitHub, where it has about 7.1k stars. The current line is version 5, with docs on a v5 subdomain. The latest release, 5.1.20, came out in October 2025, so the project is maintained, but by a small team rather than a company. You use it like other CSS and JavaScript frameworks: add the files, then build pages from its components.

Bottom line: a good free pick if you like its style and want many components in one package. For a large team project, check that the release pace and single-maintainer setup fit your needs.
