In their own words
Canal
Canal is a free, self-hosted project that parses MySQL binary logs so applications can subscribe to and consume database changes incrementally. It acts like a MySQL replica, requesting binlog data from a master and parsing the events. Listed uses include database mirroring and real-time backup, index maintenance, cache refresh, and business-logic processing. The README lists source versions MySQL 5.1.x, 5.5.x, 5.6.x, 5.7.x, and 8.0.x. Canal can send change records to Kafka and RocketMQ; the quick start also lists RabbitMQ and Pulsar server modes. Its Protocol Buffers 3.0 client-server design has clients for Java, C#, Go, and Python. Canal Admin provides a web interface for managing configuration, tasks, and logs, and the project lists native Prometheus monitoring. Docker images and a Docker QuickStart are available, but the default setup runs only one Canal instance per Docker instance. The project is licensed under Apache-2.0.
Estuary
Estuary is a managed data integration platform for combining change data capture, batch, streaming, and app synchronization for analytics, operations, and AI. It supports transformations while data is moving, using SQL, Python, or TypeScript, and describes delivery as exactly once with end-to-end latency under 100 milliseconds. More than 200 prebuilt connectors cover databases, warehouses, SaaS apps, and cloud platforms, including Snowflake, BigQuery, Kafka, MySQL, and PostgreSQL. Customers can store data in their own cloud bucket for a duration they choose, and select public, private, or Bring Your Own Cloud deployment. Estuary lists SOC 2 Type II, HIPAA, HITECH, CCPA, and GDPR among its compliance standards, and says data is encrypted in transit and at rest. It is available through API, self-hosted, and web options. The indefinite free tier is limited to 10 GB per month and two concurrent connector instances; paid plans start at $100 a month.
