covenEnd-to-end encrypted SQLite sync without a coordination server

Multi-writer sync for host-owned SQLite schemas, encrypted blobs, and cryptographic membership over bring-your-own storage.

Host-owned schema

Your app owns its tables and domain. coven owns sync bookkeeping, change capture, encryption, membership, and storage movement.

Synced rows are captured through the SQLite session extension and stamped with hybrid logical clock timestamps.

Authors sign their changesets; conflicts resolve at row level with last-writer-wins on `_updated_at`.

Sync runs through a pluggable CloudHome: S3, Google Drive, Dropbox, OneDrive, iCloud, or local storage.

Membership is an append-only Ed25519-signed chain. The library key is wrapped to each member's X25519 key.

Files referenced by rows move through a cloud outbox as encrypted opaque blobs.
