Why the foundation exists

  • We started with PrimeVue

    The MIT 4.x line last shipped in April 2026 and now gets security fixes only, while new development moved off MIT. It is still pulled from npm over 400,000 times a week.

  • The whole stack, in one place

    Components, theming engine and icon set are all maintained here, so nothing critical resolves at runtime from a scope we do not control.

  • MIT, permanently

    Every project here is MIT and stays MIT. A relicense upstream cannot reach these packages.

What is the OpenVi Foundation?
An independent, community-run organization that maintains open source UI libraries for the web. It picks up widely used front-end libraries after their original maintainers stop, and keeps them released, documented and MIT licensed.
Which projects does the foundation maintain?
Four libraries: OpenVue, the Vue component library that continues PrimeVue; OpenVolt, Tailwind CSS components for OpenVue that continue Volt; OpenIcons, which continues PrimeIcons; and OpenUXKit, the theming engine that continues PrimeUIX. It also publishes templates and starters such as the Deni admin dashboard.
Are the projects free to use commercially?
Yes. Every project the OpenVi Foundation publishes is MIT licensed and stays MIT licensed, which permits commercial use, modification and redistribution. Releases already published cannot be relicensed retroactively.
Who runs the foundation, and who funds it?
A group of engineers who know these libraries well, together with a growing set of community contributors. There is no company behind it and no funding. Commit access is granted on sustained, review-quality contribution rather than employer or affiliation.
How can I contribute?
Pick an issue on any of the project repositories, report a bug with a reproduction, improve the documentation, or test components with assistive technology. Each project lists where help is needed most on the contribute page, and conversation happens on Discord.
I use PrimeVue. Where do I start?
With OpenVue, which keeps the PrimeVue 4 component API. Running npx @openvue/migrate in a PrimeVue 4 project renames the packages and rewrites the imports in one reviewable diff, and the OpenVue migration guide covers icons, Volt and older versions.
Is the foundation affiliated with PrimeTek?
No. The OpenVi Foundation is not affiliated with, sponsored by, or endorsed by PrimeTek Informatics or PrimeUI. The projects continue upstream work under its original MIT license, with attribution.
