Decodable review
A usage-priced managed CDC platform with Flink, Debezium connectors, and serverless deployment.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Decodable is a serverless real-time data engineering platform for data engineers, application developers, and data scientists. Its change data capture capabilities read database transaction logs and deliver inserts, updates, and deletes to downstream systems through Debezium-powered connectors. The platform also connects databases, event-streaming systems, APIs, warehouses, and other destinations, with web and API access plus declarative configuration through its CLI and API.
Pricing is usage-based rather than subscription-based. The Free plan includes a fully managed Apache Flink runtime, fully managed connector library, serverless control plane, and serverless data plane. On Demand includes the same features at $0.12 per credit with monthly billing. Enterprise also includes those capabilities, adds a serverless or BYOC data plane, and offers custom task sizes at $0.10 per credit with annual billing. This structure suits teams that want to align spend with usage, while Enterprise is the option for organizations needing BYOC deployment or custom task sizing.
Decodable’s broader fit comes from its integration and processing surface: Apache Kafka, Apache Pulsar, Amazon DynamoDB CDC, Amazon Kinesis, Amazon S3, Confluent Cloud, Google Cloud Pub/Sub, Microsoft SQL Server CDC, MongoDB CDC, MySQL CDC, Oracle CDC, Postgres CDC, Redpanda, REST, and Apache Iceberg are included in the integration list. Initial table snapshots are available for supported CDC connectors, and supported connectors can provide exactly-once processing. A key limitation is schema operations: upstream schema changes are not automatically picked up and require manual schema updates and connection restarts. Choose Decodable for managed, usage-priced CDC with stream processing; consider an alternative if automatic schema evolution is essential.
