There is the litereplica
The engine is embedded in the sqlite code. Implements master-slave replication and point-in-time recovery.
It uses the GO language, implements master-slave replication with automatic failover.
And the ActorDB
This last one I don't know very well, but it appears to share the WAL log file through the servers/devices.
For data synchronization there is the WebSqlSync
It runs on browsers and even on mobile devices (Android, iOS, etc) and is capable of keeping a local SQLite db in sync with another in a server.
