Bluesky is a decentralized social media platform built on the AT Protocol, offering an open and interoperable alternative to traditional centralized networks. It allows users to find communities, share content, and connect with others without being locked into a single company's ecosystem. Bluesky is ideal for anyone who wants more control over their social experience, from casual browsers to creators and developers.

What is Bluesky and how does it work?

Bluesky is a social networking service launched by Jack Dorsey, co-founder of Twitter, that operates on an open protocol called the AT Protocol. Unlike conventional social platforms, Bluesky does not store all data on a single server; instead, it uses a federated architecture where users can choose their own hosting providers, known as Personal Data Providers (PDS), while still interacting freely across the network. The platform supports standard social features such as posting text, images, and links, along with follows, reposts, likes, and thread conversations.

The core technical innovation behind Bluesky is its open protocol. Any developer can build applications on top of it, and any user can migrate their account and data between different hosting services without losing their social graph. This design directly addresses the problem of vendor lock-in that has plagued centralized platforms for years.

What are the core features of Bluesky?

Bluesky provides a set of essential social media capabilities designed to keep the experience lightweight, customizable, and community-driven.

  • Customizable Feeds — Users can subscribe to algorithmically generated or curator-created feeds tailored to specific topics, interests, or communities rather than relying solely on a generic chronological timeline.
  • Text, Image, and Link Posts — Bluesky supports rich media posting including images, videos, and embedded links, with native support for threaded conversations to enable deeper discussions.
  • Follow Graph and Interoperability — The platform's open protocol allows users to follow and interact with accounts across different PDS instances seamlessly, maintaining a unified social graph.
  • User-Controlled Moderation — Bluesky offers built-in filtering tools and a third-party moderation market, giving users granular control over what content appears in their feed and who can interact with them.
  • Decentralized Identity — Each user owns their handle and account data through the AT Protocol, enabling easy migration between hosting providers without losing connections or history.

Who is Bluesky suitable for?

Bluesky is designed for a broad audience that values openness and personalization in their social media experience. It is particularly well-suited for content creators and journalists who want a platform less dominated by engagement-driven algorithms. Community builders and niche interest groups benefit from the customizable feed system, which allows them to create and curate spaces around specific topics. Developers and technologists are drawn to the open protocol, which offers opportunities for experimentation and integration. Casual users who are frustrated with the noise and opacity of mainstream social networks also find Bluesky appealing as a cleaner, more controllable alternative.

How do you get started with Bluesky?

Getting started with Bluesky is straightforward and free. You can sign up directly at bsky.app, choose a unique handle, and select a Personal Data Provider to host your account. After verification, you can follow accounts, join topic-based feeds, and start posting immediately. The platform also recommends exploring curated feeds at launch to discover communities aligned with your interests. Mobile apps are available for both iOS and Android, providing the same functionality as the web version. Account migration between different PDS instances is supported through the Bluesky settings interface.

How does Bluesky handle content moderation and safety?

Bluesky employs a multi-layered moderation approach that combines user-level controls with platform-wide policies. Users can block specific accounts, mute keywords, and adjust their feed filters independently. The platform also participates in a growing marketplace of third-party moderation labels that users can opt into or out of at will. Content that violates Bluesky's community guidelines is subject to removal, and repeat violations can result in account restrictions. For detailed policy information and the latest safety guidelines, please refer to the official Bluesky website.
