Why choose AT Protocol?
- Self-sovereign identity using DIDs and handles, enabling seamless PDS migration
- Custom algorithmic feed generators created by the community
- High-performance design built for massive global timelines
Things to consider
- Ecosystem relies heavily on Bluesky PBC's primary relay and AppView
- Younger specification compared to W3C ActivityPub
