In their own words
Decodable
Decodable is a managed, serverless platform for real-time ETL, ELT, and stream processing, built on Apache Flink and Debezium. It lets teams create pipelines in SQL, Java, or Python and manage them through a UI, CLI, APIs, or dbt. SQL supports transformations, filtering, stateful joins, and complex event processing. Pipelines process data exactly once by default and can resume after a stop or failure. Connectors include Apache Kafka, PostgreSQL, Apache Iceberg, and Snowflake, with Debezium-powered change data capture. Teams can use Decodable-hosted infrastructure or a Bring Your Own Cloud deployment. The free plan costs nothing and does not expire or require a credit card; it includes 24 hours or 10GiB of stream retention, 20 streams, and four running tasks. On Demand costs $0.12 a month, billed monthly, and Enterprise costs $0.10 a year, billed annually with committed capacity. Decodable is available via API, web, and self-hosted deployment.
Sequin
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.
