There Are No Instances in ATProto

# Summary ATProto differs fundamentally from Mastodon's federated instance model—there are no instances in ATProto because it uses a different architecture inspired by RSS and blogging rather than decentralized social media platforms. While Mastodon requires users to choose and belong to a specific instance (creating identities like [email protected]), ATProto separates hosting from aggregation, allowing users to own their identity independently and switch between different apps and services without being tied to any single platform or server.
