Call for Developers

Published on: Aug 3, 2023

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.

Read more about the AT Protocol here and check out some third-party developer projects here.

To receive atproto updates in your inbox, subscribe to the developer mailing list.

Join the Federated Sandbox

No waitlist or invite code required to join this self-hosted sandbox environment. The production network will open to federation soon.
