Lucas Larroche archived the repositories on on Oct. 4, 2026. The maintainer called v2.1.1 the final release. The project is now read-only.
The decision tracks a shift in frontend development. Larroche said developers now use AI to generate lightweight, standalone, accessible HTML with only the CSS it requires. That reduces demand for a minimal framework built around semantic HTML. To stay relevant, Pico would need a full rewrite: plain modern CSS instead of Sass, OKLCH colors, cascade layers, the Popover API, anchor positioning, fallbacks for older browsers, and a native compiler that strips unused styles. Larroche said that result would be a different project, not an updated Pico.
The archive does not break existing sites. npm packages and the jsDelivr CDN stay live. picocss.com remains online too. No one can submit new issues, pull requests, or releases.
The MIT license still applies. You can fork the code and extend it. The MIT license does not cover the Pico CSS name and logo, so any fork needs its own branding. Larroche directed users to .
Pico began as a side project and powered thousands of websites. Larroche thanked users, contributors, and anyone who sent kind messages over the years.
