Beyond Bluesky: These are the apps building social experiences on the AT Protocol | TechCrunch
A list of AT Protocol-based, consumer-facing apps that are either built on top of Bluesky or its underlying protocol, allowing users to take back control over their social networking experiences and personal data.

AT Protocol
The AT Protocol is a protocol and open standard for distributed social networking services. It is under development by Bluesky Social PBC, a public benefit corporation originally created as an independent research group within Twitter, Inc. to investigate the possibility of decentralizing the service.
Bluesky Protocol Services
High scale open social, unlocked for every builder. Bluesky operates public infrastructure for the AT Protocol — Jetstream, Relay, and the Bluesky API — as open services anyone can build on.

Explore and discover AT Protocol data with our fast, user-friendly browser. Search posts, profiles, and feeds across the decentralized social web — including apps like Bluesky.
AT Protocol accounts · uchu.social

*This endpoint is part of the Bluesky application Lexicon APIs (`app.bsky.*`). Public endpoints which don't require authentication can be made directly against the public Bluesky AppView API: https://public.api.bsky.app. Authenticated requests are usually made to the user's PDS, with automatic service proxying. Authenticated requests can be used for both public and non-public endpoints.*

Recently I’ve been thinking about a couple of different tech-related things that sort of overlap.
