Bluesky

Bluesky is an open-source decentralized social network. It provides a platform for users to interact and share content while maintaining control over their own data and experience. The software is designed to move away from centralized control by utilizing a federated approach to social media.

The software is available as a web application and as mobile apps for iOS and Android. It is developed using React Native and the TypeScript programming language, while a small Go language source code component handles the web service that returns the React Native Web application. Users interact with the network through these clients to post updates and engage with other accounts.

Key features

• Decentralized architecture based on the AT Protocol
• Cross-platform availability via web, iOS, and Android
• Support for custom feeds and federated services
• Open API access through the app.bsky.* lexicon namespace
• Third-party client integration capabilities
• MIT licensed codebase allowing for community forks
• Integration with atproto TypeScript packages

The application is built on the Authenticated Transfer Protocol (AT Protocol), which serves as the underlying framework for its schemas and APIs. This architecture allows developers to create third-party integrations, such as custom feeds and independent clients, that interact with the network without being locked out of the ecosystem. The system uses a specific namespace for its lexicons to ensure consistency across the protocol. Because the codebase is open source, other developers can fork the application to create their own branded versions, provided they replace the original branding and support links.

Bluesky is an open social ecosystem designed to prevent developer lock-in through its decentralized protocol and open API standards.
