AT Protocol Development

The AT Protocol (also called ATProto, the technology that is best known for powering the Bluesky social network) represents the future of decentralized social networking, but building on this platform requires deep understanding of its unique architecture, data models, identity systems, and federation concepts. We can help teams navigate ATProto's lexicon system, Personal Data Servers (PDS), and the complexities of building interoperable social applications.

Our ATProto Expertise

With hands-on experience building the popular Bluesky Directory and other ATProto applications, we understand the unique challenges (and benefits!) of developing on this platform:

• Real-time Data Processing: We've built systems that consume the Bluesky firehose to process millions of profiles, feeds, posts, and other objects.
• API Integration: Deep experience with ATProto APIs, authentication, and rate limiting
• Custom Feed Development: Created and deployed custom algorithms for content discovery
• Cross-Platform Compatibility: Designed applications that work seamlessly across mobile, web, and desktop platforms
• Platform Interoperability: Built systems that integrate with other ATProto applications and services
