sequinstream/sequin

Sequin is a self-hosted change data capture (CDC) platform that captures database changes from PostgreSQL and routes them to a wide variety of sinks, including Kafka, AWS services, and search engines. The system provides a comprehensive web console and CLI for managing pipelines, functions, and configurations, while also offering a robust set of Svelte-based UI components for building the interface. It supports complex data processing through user-defined functions and transforms, with built-in health monitoring, metrics, and logging capabilities.

The project underwent a comprehensive rebranding from SequinStream to Sequin, unifying the codebase and configuration namespaces. This period focused on rebuilding the web console with a new Svelte-based UI, introducing robust user authentication, and implementing a full suite of API controllers and health monitoring systems.

This period focused on significantly expanding the platform's data sink capabilities, adding native support for diverse destinations including Kafka, Elasticsearch, Typesense, Meilisearch, and various cloud services. Concurrently, the runtime architecture was refactored to support modular, high-throughput message processing and dynamic routing, while the UI was updated to provide comprehensive configuration interfaces for these new sinks.
