Instance data

A Community Edition instance stores durable data in the PostgreSQL database configured by DATABASE_URL.

The database contains:

• Accounts, sessions, workspaces, members, and invitations.
• Feeds, watched pages, folders, and articles.
• Reading state, sharing settings, and API keys.
• Saved Spark AI threads and messages.
• Cached catalogue and feed-health data.

Back up PostgreSQL before an upgrade. Follow the export and backup guide for Compose and standard PostgreSQL commands.

Demo mode uses a separate SQLite file. Deleting rss-demo.db resets only demo data.
