Twitter is experimenting with new ways to limit Spaces to smaller groups

Twitter is now testing two new Spaces audience choices that would allow Spaces hosts to restrict access to only those who they directly invite, or only 'tweeps' - aka your followers.

Despite being launched more than a year ago, Spaces is still in its early stages of growth. Even though Twitter has made significant progress with the option since its early testing, which was sparked by the sudden surge in interest in Clubhouse. The dedicated Spaces tab, for example, is still not available to all users, indicating that the option still has a ways to go in terms of maximising its potential and truly testing whether it can become a more essential element in the overall tweet process.
