DBConvert Streams vs Debezium

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.

Debezium captures row-level database changes and delivers them to applications as events, so they can respond to inserts, updates, and deletes. Its connectors use database logs for low-delay capture without requiring changes to the data model, and can take initial or incremental snapshots, filter schemas, tables, and columns, and mask selected values. Listed databases include MongoDB, MariaDB, MySQL, PostgreSQL, SQL Server, Oracle, Db2, and Cassandra. Connectors for Vitess, Spanner, Informix, CockroachDB, YashanDB, Ingres, and Milvus are marked incubating and may change without backward compatibility. A common deployment uses Apache Kafka Connect; Debezium can also run through Debezium Server or as a library in JVM applications. Debezium Server can send serialized events to Amazon Kinesis, Google Cloud Pub/Sub, and Apache Pulsar. Ready-to-use transformations support routing, filtering, and event flattening. Debezium is free under the Apache Software License 2.0. Its quay.io container images are for testing and evaluation, not production.
