Overview
Description

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.

Mastodon is a decentralized, open-source social media platform that allows users to host their own servers and connect with others across the globe. It provides a unique alternative to traditional social media platforms, giving users more control over their data and online presence.
