Summary

dsync is a data migration and replication tool for moving data between databases and other stores, either once or through ongoing replication. After an initial sync, it can monitor source changes and apply them to the destination. The open source edition is a single binary that can run on a laptop, VM or Docker container. Listed connectors include MongoDB, Cosmos DB, DynamoDB, AWS DocumentDB, PostgreSQL, S3 and CSV files, while several others remain in preview or development. Integrity checks range from namespace counts to complete hash-based verification, and interrupted initial copies or change-capture flows can resume from saved state. Progress appears in the CLI and a web page hosted on the machine running dsync. Adiom says the tool does not store data and supports network encryption. Transformations can be performed through external processes connected over gRPC. A limitation is that source DDL statements and indexes are not replicated. With a metadata store for resumability, the open source version has a 16 MB read-plan cap. Enterprise adds horizontal scalability, observability and transformations; Adiom offers commercial support for both editions.

Who it is for

dsync is aimed at engineers and DevOps teams at enterprises and fast-growing companies that need database migration or replication. The open source edition may suit small projects and testing.

What is good

Supports one-time migrations and continuous replication.
Can resume interrupted sync and change capture.
Offers quick counts and hash-based verification.
Progress is available in CLI and a local web page.
Open source edition is free forever.

What to know first

Does not replicate source DDL statements or indexes.
Open source read plan has a 16 MB cap with metadata store.
Some connectors are in preview or development.

Verdict

dsync provides migration, change capture, verification and resumability in a self-hosted tool. Account for the DDL and index limitation and the open source read-plan cap when assessing a workload.
