DBSync vs PeerDB

DBSync automates data replication, consolidation, and capture of changes between systems. It supports real-time, two-way database synchronization through change data capture (CDC), and can replicate Salesforce, Dynamics 365, and Business Central data to databases, data lakes, and warehouses. Data Compare helps find mismatches between datasets for comparison and consolidation. Jobs can run on a schedule or in response to events; supported methods include CDC, ELT, ETL, and Reverse ETL. Deployment options include on-premise and cloud-hosted setups. Listed endpoints include SQL Server, SQLite, MySQL, PostgreSQL, Oracle, IBM Db2, MongoDB, Snowflake, AWS Redshift, AWS S3, Azure Synapse, Databricks, and MinIO. Documentation lists Batch API and J2EE Web Server modes, with EXE, Zip, Docker, and AWS Images deployments. A free Developer plan includes two connectors, up to 10,000 records, and up to three objects. A 14-day trial includes plan features and up to two standard connectors. Paid plans require an annual contract, and add-ons may cost extra.

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Elasticsearch, Kafka, Redpanda, Confluent, Azure Event Hubs, Google Pub/Sub, and S3 destinations are deprecated and no longer actively maintained.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.
