Description

Bluesky is a decentralised social media platform originally developed as a research project within Twitter, now operating as an independent service. Unlike traditional platforms, Bluesky uses the AT Protocol (Authenticated Transfer Protocol) to enable users to host their own data or switch providers without losing their identity, posts, or social connections. It is designed to break the control of a single corporation over user data, moderation policies and content discovery algorithms, offering a more open and user-controlled social experience.

As a substitute for Twitter/X, Bluesky provides a platform where users can create and share content, follow others and engage in conversations with a focus on user autonomy and modularity. Its main features include account portability, custom algorithmic feeds, composable moderation tools and the ability to host your own server or data. Bluesky is ad-free and free of charge and its modular design allows users to choose or create custom feeds and moderation services. The platform has gained popularity due to its familiar Twitter-like interface and its commitment to user control and data portability.

Bluesky has faced controversies, particularly regarding its use of the AT Protocol instead of the more widely adopted ActivityPub, which limits its interoperability with other Fediverse platforms like Mastodon and Pixelfed. Critics argue that this choice could hinder Bluesky’s reach and integration with the broader decentralized social web. Additionally, while Bluesky promotes decentralisation, some users question how truly decentralised it is, as the main app is not fully open-source and the network’s growth has been driven by a centralized service. The platform has also experienced fluctuations in user activity, with a notable decline in daily active users after an initial surge.
