Architecture

atbbs has no backend database for content. All BBS data lives in atproto repos:

• Sysop records: xyz.atboards.site, xyz.atboards.board, xyz.atboards.news
• User records: xyz.atboards.thread, xyz.atboards.reply

The web app and TUI query existing network infrastructure:

• Slingshot — cached record and identity fetching
• Constellation — backlink index for discovering threads and replies
• UFOs — BBS discovery feed

Configuration

On first run, atbbs generates:

• secrets.json — app secret key and OAuth client signing key
• atbbs.db — SQLite database for OAuth sessions

Web app: Set ATBBS_DATA_DIR to control where these are stored (default: current directory, /data in Docker). Set PUBLIC_URL to your domain for OAuth callbacks.

TUI: Data is stored in ~/.local/share/atbbs/ (Linux), ~/Library/Application Support/atbbs/ (macOS), or %APPDATA%/atbbs/ (Windows).
