Spec score 7.9 #12 of 23 in Change Data Capture Software

What it is

Sequin streams changes from PostgreSQL to destinations such as Kafka, Redis, queues, search indexes, and webhooks. It runs as a Docker image alongside the database and can be started with Docker Compose, so deployment is self-hosted. Users can filter and transform changes, add data from Postgres, and route results to destinations including AWS SQS, GCP Pub/Sub, NATS, Elasticsearch, Typesense, and Meilisearch. Backfills can start at the beginning of a table or a chosen point, and can replay selected rows. Sequin describes delivery as using automatic retries, exponential backoff, strict ordering, and exactly-once processing. Sinks can be managed through a console, CLI, YAML configuration, or API. Monitoring includes a Prometheus metrics endpoint and Grafana dashboard. PostgreSQL 14 or later is supported; versions 12 and 13 have limitations. Sequin is open source under the MIT license, with a listed self-hosted plan at free. Sequin Cloud shut down on October 23, 2025; the project continues in maintenance mode with security patches and critical bug fixes.
