Explore open-source libraries, clients, and utilities built for the AT Protocol and Bluesky social ecosystem.
This project provides a comprehensive implementation of the AT Protocol, serving as a framework for building decentralized social networking applications. It enables the creation of distributed data repositories where users maintain cryptographic ownership of their identity and content, allowing for portable accounts that can be migrated between independent servers without central authority intervention. The platform distinguishes itself by decoupling content hosting from discovery through modular algorithmic curation. Users can select third-party services to filter and organize their feeds, while content moderation is handled through a flexible labeling system that allows for both automated and community-driven content standards. By utilizing content-addressed storage and cryptographically signed records, the system ensures that data integrity can be independently verified across the network. Beyond core identity and storage, the project includes infrastructure for real-time network event streaming, media distribution, and global data aggregation. It supports complex social interactions through automated agents and provides tools for managing distributed repository state, including historical data backfilling and scalable traffic management. The repository contains the necessary tools and services to interact with the federated network, including standardized authentication flows and schema-based data interoperability.
This repository serves as the primary reference implementation for the AT Protocol, providing the core infrastructure for decentralized identity, data repository management, and real-time network interaction required for the ecosystem.
Mastodon is a self-hosted, decentralized social networking platform that functions as a microblogging application. It enables independent server instances to communicate and exchange social data through the standardized ActivityPub protocol, allowing users to participate in a global, interoperable network. The platform distinguishes itself through its federated architecture, which grants administrators full control over their community instances. This includes comprehensive tools for user moderation, account management, and the enforcement of community guidelines. The system is designed to handle high-traffic environments, utilizing background processing for heavy tasks and persistent connections to deliver real-time updates and notifications to users. Beyond its core social features, the platform provides a robust administrative surface for managing server identity, network security, and infrastructure scaling. It supports complex content discovery through optional external search engine integration and offers a comprehensive API for managing accounts, statuses, media attachments, and server-wide announcements. The software is configured primarily through environment variables, allowing for flexible deployment across diverse hosting environments. Administrative tasks, including system maintenance and user management, are supported through a command-line interface.
Mastodon is a decentralized social networking platform built on the ActivityPub protocol, which is a distinct and separate ecosystem from the AT Protocol.
