_{Early preview, still research, built in public. Follow along on X and Bluesky.}

 

01   The idea

Focus. Keyboard. ARIA. State. The parts that take months, written once, below the framework. Above it, a thin layer that speaks React, Vue, Svelte, Angular and Solid.

No styles. Your rules.

 

02   Three layers, one behavior

 

03   Proven the same, five times

Every adapter runs the same upstream behavior tests. A parity harness drives the same scenarios with real input in Chromium, Firefox and WebKit, and compares the DOM, the events and the focus of all five frameworks.

See it yourself on Compare: pick a component and try it in all five side by side. Open one dialog and the other four follow.

 

04   The catalog

Every component in all five frameworks, with server rendering and hydration.

Coming next: Fieldset, and the rest of #4.

 

05   Early access

No account, no sign-in. Leave your email, the frameworks you use and, if you like, your GitHub username.

 

06   Sponsor the launch

Five frameworks, one core, every behavior tested five times: that is a lot of full-time work before 1.0. If your team plans to use it, sponsoring now helps it ship sooner and keeps it independent.
