Mantle Ui
Fiscal Host: Open Source Collective
Mantle UI is a community-driven open-source project focused on the development and long-term maintenance of a React UI component library.
About
Mantle UI is a community-driven continuation of PrimeReact v10.
The project was created after PrimeTek archived the original open-source PrimeReact repository and moved the future development of PrimeReact v11 to a new model. This sudden change left users of the MIT-licensed v10 codebase without a clear path for continued community-led maintenance and development.
Mantle UI preserves that open-source foundation and carries it forward as an independent project. Our goal is to provide existing users with a stable migration path while continuing to fix bugs, improve accessibility, maintain compatibility with the modern React ecosystem, and develop the component library openly and transparently.
Mantle UI is maintained by its community rather than being dependent on the priorities of a single company. Contributions through Open Collective support ongoing development, documentation, infrastructure, and the long-term sustainability of the project.
