DBConvert Streams vs PeerDB

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.

PeerDB streams data from Postgres to data warehouses, queues, and storage engines, using one-way replication. Its supported methods include log-based change data capture, cursor-based replication with timestamps or integers, and XMIN-based replication. A Postgres-compatible SQL interface supports ETL and data movement, and PeerDB handles Postgres data types such as jsonb, arrays, and PostGIS, as well as TOAST columns and schema changes. The actively maintained source connectors are PostgreSQL, MySQL, MongoDB, CockroachDB, and BigQuery; actively maintained destinations are ClickHouse, ClickHouse Cloud, and Postgres. Snowflake, BigQuery, Elasticsearch, Kafka, Redpanda, Confluent, Azure Event Hubs, Google Pub/Sub, and S3 destinations are deprecated and no longer actively maintained. PeerDB is available for free deployment under the AGPL-3.0 license. Paid plans start at $250/mo for Micro, which allows up to two vcores and is recommended for up to 50 million rows moved per month. Larger plans list higher row-volume recommendations and vcore limits. PeerDB states that it is 10x faster than existing tools and reports SOC 2 Type II and GDPR compliance.
