Debezium: Pricing, Features & Alternatives
Debezium reads a database’s transaction log and turns each row change into an event your other systems can consume. It ships stable connectors for PostgreSQL, MySQL, MariaDB, MongoDB, SQL Server, Oracle, Db2 and CockroachDB, with more (Cassandra, Spanner, Vitess, TiDB and others) incubating. You can run it on Kafka Connect, as the standalone Debezium Server with no Kafka required, or embedded as a library. It is Apache 2.0 licensed and hosted by the Commonhaus Foundation; 3.7.1.Final shipped on November 6 2026. There is no paid tier: you run and monitor it yourself.
Who it’s for: Backend and platform engineers who want log-based CDC under an Apache licence and are happy to operate it.
