PeerDB vs Tantor Low-Code CDC

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Elasticsearch, Kafka, Redpanda, Confluent, Azure Event Hubs, Google Pub/Sub, and S3 destinations are deprecated and no longer actively maintained.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

Tantor Low-Code CDC provides a visual way to stream database inserts, updates, and deletes into governed pipelines without writing code. Users select source tables and choose capture operations and masking rules through guided controls. The product detects and masks personally identifiable information before downstream delivery and handles source schema changes automatically. Each captured change carries row-level lineage for auditability. Tantor names Oracle, PostgreSQL, SQL Server, MongoDB, and MySQL as supported sources. Its broader CDC platform uses log-based capture from transaction logs without triggers or queries, and says changes reach its federation layer and AI agents in under 60 seconds. Captured changes are immutably logged with what changed, when, where it came from, and who consumed it. Governed data can flow to lakehouses, agents, and analytics. Deployment supports on-premises, private cloud, and air-gapped environments, with a hybrid model. Tantor describes regulated-industry use, including BFSI, healthcare, and utilities.
