dbmazz review
A focused, open-source CDC daemon for small self-hosted database pipelines.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
dbmazz is an open-source change data capture daemon for teams that need to stream changes from PostgreSQL or MySQL into analytical and operational destinations. It reads PostgreSQL WAL logical-replication streams and MySQL binlogs, then delivers events to StarRocks, PostgreSQL, or Snowflake. The product is designed for self-hosted operation as a single Rust binary or Docker container, making it a focused option for small CDC setups that do not need Kafka, ZooKeeper, or Flink in the deployment.
Its strongest area is the core capture and recovery workflow. dbmazz supports ongoing log-based streaming, initial and incremental snapshots, checkpoint persistence, and crash recovery. It can also handle schema evolution and automatically create publications, replication slots, sink tables, and audit columns. Healthchecks, metrics, and a control API provide operational visibility. Docker images are available for amd64 and arm64, while the listed platforms include Linux, macOS, API, and self-hosted deployment.
The main trade-off is scope. Integrations are centered on PostgreSQL, MySQL, StarRocks, and Snowflake, so teams needing a wider connector ecosystem may need another CDC product. The published model is free and open source with self-hosted deployment, while the broader EZ-CDC offering describes a free BYOC option and separately charged support and connectivity. Choose dbmazz when a compact PostgreSQL or MySQL pipeline fits your architecture and your team can operate the deployment. Choose an alternative when broader destination coverage or a managed operating model is the priority.
dbmazz pros and cons
- Where it wins
- Log-based CDC for PostgreSQL WAL and MySQL binlog with GTID support
- Snapshots, checkpoints, crash recovery, and schema evolution
- Docker images for amd64 and arm64 with health and metrics APIs
- Where it doesn't
- Connector coverage is limited to four database and destination systems
- Self-hosted deployment requires managing the runtime environment
- Advanced support and connectivity are separate from the free engine
