Updated
In short: SymmetricDS is ranked #1 of 30 as of 4 October 2026, ahead of DBConvert Streams and dsync. The best-ranked option with a free plan is DBConvert Streams. The lowest first paid tier on this page is Google Cloud Datastream at $0.40/mo.
Moving data between systems raises practical questions about database coverage, where replication runs, and how changes are handled. Compare supported databases and replication direction, then look at change data capture, cross-region replication, and data transformations. Deployment options can help you assess fit with your environment, while free-plan availability and paid-from pricing provide cost context. SymmetricDS, DBConvert Streams, and Artie are among the named options. Consider which replication patterns and transformations your work calls for, and weigh those needs against the databases and deployment choices each entry lists.
