DBConvert Streams vs dsync

DBConvert Streams combines a database IDE for exploration and SQL with migration and change-data-capture streaming. One-time Load migrations and ongoing CDC replication are supported; MySQL CDC uses binlog replication and PostgreSQL CDC uses logical replication. Connectors include MySQL, PostgreSQL, Snowflake, local files, S3-compatible storage, and federated queries. Embedded DuckDB lets federated SQL join databases and file or object-storage sources in one statement. Local-file workflows handle CSV, JSON, JSONL, and Parquet, with CSV, JSONL, and Parquet listed as target formats. The software runs as a Windows, macOS, or Linux desktop application, or as Docker on a server, VPS, bare metal, or cloud VM. CDC does not need Kafka, Zookeeper, or Kubernetes; NATS is bundled in the desktop app or Docker Compose stack. It also offers an AI assistant, read-only MCP operations, and more than 80 REST endpoints. The Free plan is free and includes an IDE, viewers, extensions, and federated queries across two sources. Its CDC trial lasts seven days from the first stream and covers up to three tables.

dsync moves data between databases and other data stores through one-time migrations or ongoing, one-way replication. After the initial copy, it can watch the source and apply later changes at the destination. The open source edition is a single binary that can run on a laptop, VM, or Docker container. Connectors include MongoDB, Cosmos DB, DynamoDB, AWS DocumentDB, PostgreSQL, S3, and CSV files; several others are still in preview or development. Checks range from quick namespace counts to full hash-based verification, and saved state lets an initial copy or change-capture flow resume. Progress appears in the CLI and a web page hosted on the machine running dsync. Adiom says dsync does not store data and supports network encryption. Transformations can use external processes connected over gRPC. It does not replicate source DDL statements or indexes. With a metadata store for resumability, the open source version has a 16 MB read-plan cap. Enterprise adds horizontal scalability, observability, and transformations. The open source plan is free.
