Skip if

You need the largest possible existing audience or a single unified moderation policy.

What is Bluesky?

Bluesky is a decentralized social networking app built on the open AT Protocol, letting users choose or build custom algorithmic, chronological, or topic-based feeds rather than being locked into one company's ranking algorithm. It operates as a Public Benefit Corporation and offers moderation lists and content filters so users can control what appears in their timeline. Because it's built on an open protocol, a single Bluesky account can work across other compatible third-party apps and services, and developers can build custom feeds, bots, and alternative clients using open APIs. The service is free to use via web, iOS, and Android.

Each community is tied to a specific university, verified by student status. Since launching on campuses, Fizz has expanded to a personalized feed that also surfaces posts from adjacent or nearby college communities a student naturally overlaps with, moving beyond a single-campus board while keeping the same anonymous, no-performance format. It is currently live at 750+ colleges and universities.
