Bluesky is an open social network built on the AT Protocol, a flexible technology that will never lock developers out of the ecosystems that they help build. With atproto, third-party can be as seamless as first-party through custom feeds, federated services, clients, and more.
If you're a developer interested in building on atproto, we'd love to email you an invite code. Simply share your GitHub (or similar) profile with us via this form.
