jet_ui

Rails UI components collection out-of-the-box, created by JetRockets, and put together all in the template project https://ui.jetrockets.com — turned gem by RPA, to make it real easy for devs to include them in their rails projects (new or existent). Maintained by jetrockets on GitHub, where it has earned 43 stars from the community.

It's actively developed around components, hotwire-rails, hotwire-stimulus, and is a solid reference for anyone building with these tools.
