Overview
Bluesky is a social media platform designed to operate as an open network rather than a closed platform controlled by a single corporation. Built on the AT Protocol, it enables users to own their identity and data while maintaining a cohesive, easy-to-use experience across multiple interoperable apps.
The platform emphasizes user choice and control through customizable feeds, composable moderation tools, and account portability. Unlike traditional social networks, users can switch hosting providers without losing their username, followers, or content. Bluesky has grown to over 44 million users as of May 2026 and operates as a Public Benefit Corporation.
Developers can build on Bluesky's open APIs to create custom feeds, bots, clients, and other applications within a growing ecosystem that prioritizes interoperability and user autonomy.
