dsync review
A self-hosted, open-source choice for one-way synchronization across many data stores.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
dsync is Adiom’s open-source database migration and replication tool for engineers and DevOps teams. It performs an initial synchronization between supported relational, NoSQL, vector, and storage systems, then can continuously capture source changes and apply them to a destination. The software is available for web, macOS, and Linux, with deployment options including a binary, Docker container, VM workload, or multi-worker system. It is best suited to teams that want to manage synchronization infrastructure themselves across varied data platforms.
Its strongest technical fit is the combination of migration controls and ongoing replication. Namespace filtering and remapping help target specific data areas, while fast count and hash-based checks support integrity verification. Initial synchronization and CDC can resume after interruption, and CLI or web-based progress reporting provides operational visibility. Write-rate limiting and configurable load levels help teams control destination pressure. A reverse option supports reverse replication flow, although the current operating model is one-way by default. gRPC-based connector and transformation interfaces also provide a path for custom integration work.
The integration range is a major consideration: dsync supports systems including MongoDB, Azure Cosmos DB, DynamoDB, HBase, Cassandra, CouchDB, PostgreSQL, SQL Server, Oracle, DB2, Weaviate, Qdrant, S3 Vector Index, S3 Storage, and File. The Open Source plan is positioned for small projects and testing, with best-effort support and a commercial support add-on. Enterprise adds commercial support, roadmap prioritization, and customization. Choose dsync if self-hosting, open-source access, CDC, and multi-database coverage matter more than a managed service experience. Teams seeking built-in bidirectional replication or minimal infrastructure ownership should consider alternatives.
dsync pros and cons
- Where it wins
- Initial sync can continue with CDC replication
- Integrity checks, resumability, filtering, and rate limiting
- Connectors cover relational, NoSQL, vector, and storage systems
- Where it doesn't
- Self-hosted deployment requires engineering ownership
- One-way replication is the current operating model
- Enterprise customization and roadmap prioritization require a paid tier
