Sequin is an open-source change data capture (CDC) platform for Postgres, deployed as a standalone Docker container that streams database changes to sinks like Kafka, SQS, GCP Pub/Sub, Redis, Elasticsearch, and webhooks. It supports backfills, exactly-once processing with strict ordering, and includes a web console plus Prometheus/Grafana observability.

Use cases

• stream postgres changes to kafka
• sync postgres to elasticsearch in real time
• send database change events to sqs or pub/sub
• keep redis cache in sync with postgres
• create audit logs from database changes
• replace debezium for postgres cdc
• backfill existing rows to a queue
• trigger webhooks on postgres row changes

When to choose

• you need real-time Postgres CDC with sub-second latency and exactly-once delivery
• you want a simple standalone Docker deployment instead of Kafka + Zookeeper + Kafka Connect
• you need to fan out changes to multiple sinks like queues, search indexes, and webhooks
• you need to backfill existing table rows alongside streaming new changes

When to avoid

• you need batch ETL into a data warehouse on minute-to-hour schedules (use Fivetran or Airbyte)
• your source database is not Postgres
• you cannot run a Docker container next to your database
• you only need Postgres-to-Postgres replication via native logical replication
