Bluesky

Open, federated microblogging platform on the AT Protocol — the most active X (Twitter) alternative for the tech audience.

Definition

Bluesky is a microblogging platform built on the open AT Protocol. It positions itself as the successor to early-Twitter's developer-friendly model: open API, custom feeds, federation, no advertising. By 2026 it is the secondary distribution channel of choice for technical content alongside LinkedIn, having absorbed much of the developer audience that left X.
