After more than a year as an exclusive invite-only social media platform, Bluesky is now open to the public, so anyone can join without needing a once-coveted invite code.

In a blog, Bluesky said that requiring invite codes helped Bluesky "manage growth" while building features that allow users to control what content they see on the social platform.

When Bluesky debuted, many viewed it as a potential Twitter killer, but limited access to Bluesky may have weakened momentum. As of January 2024, Bluesky has more than 3 million users. That's significantly less than X (formerly Twitter), which estimates suggest currently boasts more than 400 million global users.
