ATmosphere

This is the ATmosphere plugin repo.

Publish your WordPress posts to the AT Protocol network — cross-post to Bluesky, register your articles as standard.site documents on your PDS, use your domain as your Bluesky handle, and mirror replies and reposts back into WordPress as native comments.

Protocol Support

ATmosphere implements the AT Protocol natively — no third-party proxy or intermediary service. Authentication uses OAuth 2.1 with PKCE and DPoP. Records are written to your PDS via com.atproto.repo.applyWrites.

Currently supported record types:

• app.bsky.feed.post — Bluesky posts and reply threads.
• site.standard.publication — your site as a publication record.
• site.standard.document — one document record per WordPress post.

See docs/content-formats.md for more on the content union used by site.standard.document.
