PrimeNG is no longer open source. As of June 2026, PrimeTek archived the official PrimeNG GitHub repository and moved future major versions (starting with v22) to a commercial licensing model.

To ensure continued open-source support for those who rely on it, OpenNG has created Optimus UI, a community fork based on the final MIT-licensed version of PrimeNG.

We are currently working on the first release! You can follow our progress and join the discussion on our roadmap.
