AT Protocol Spaces alpha adds gated, non-public data
The AT Protocol team released an alpha of Spaces, a primitive for gated data that is not fully public. It is not for production use, and data on the temporary alpha PDS may be deleted.

On August 20, 2026, the AT Protocol blog said Spaces alpha is available for developers. A space is described as a miniature atproto network that a space-authority DID can gate so only certain people and apps can read the data.
What we know
- Spaces provide access control, not confidentiality: anyone or any app with access can read the data; it is not encrypted.
- The hosted alpha PDS is a shared sandbox; data is neither permanent nor stable, and the PDS will be deleted after the alpha.
- TypeScript @atproto packages shipped as alpha snapshots, with a sample bulletin-board app at bulletin.my.
- A spaces-capable PDS image is published at ghcr.io/bluesky-social/atproto:pds-spaces-alpha, marked as not for production.
Takeaways
- Spaces close the “everything is public” gap without claiming encryption.
- Alpha data can disappear; the hosted PDS is temporary.
- SDKs, a sample app, and a Docker PDS image are out for experiments only.
