Bluesky is a social app for short text posts, photos and videos. It began in 2019 as a project funded by Twitter under Jack Dorsey and became an independent public benefit company. The app opened in invite only beta in 2023 and opened to everyone in February 2024. Jay Graber is the chief executive.
Bluesky looks much like the old Twitter. Users post, reply, repost and quote, and follow other accounts. It runs on the AT Protocol, an open network that lets people move their account and followers to another provider. Users can choose custom feeds built by others, subscribe to block lists and add moderation services on top of Bluesky's own. People can verify their handle by using a domain name they own.
Bluesky is free and has no ads in the main feed. The company has raised venture funding and plans to earn money through optional paid features. It runs on iOS, Android and the web. Its user base grew quickly in late 2024, when many journalists, academics and public figures in the US, the UK, Canada and Europe moved from X.
