The short version

  • Each has a real cost: Decodable credit pricing rewards intermittent work and penalises always-on pipelines: a single small task running continuously costs roughly 86 US dollars a month before any parallelism.; Estuary per-GB pricing adds up quickly for high-volume scenarios
  • They diverge on capability: Decodable covers Managed Flink, Estuary covers Real-time data delivery.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Decodable

  • Credit pricing rewards intermittent work and penalises always-on pipelines: a single small task running continuously costs roughly 86 US dollars a month before any parallelism.
  • Parallelism multiplies tasks, so scaling a pipeline to keep up with throughput multiplies the bill in a way that is easy to under-forecast at design time.
  • The free tier retains streams for only 24 hours, which is too short to debug an intermittent failure that surfaces days later.
  • Java and Python transformations are gated behind paid plans, so anything the SQL layer cannot express means moving off the free tier immediately.
  • The operational layer is proprietary even though Flink and Debezium are not, so migrating to self-managed Flink later means rebuilding connectors, schema handling and monitoring from scratch.

Estuary

  • Per-GB pricing adds up quickly for high-volume scenarios
  • No transparent per-connector volume discounts below 6 connectors
  • Limited to data movement; transformation capabilities are basic
  • BYOC and private deployment requires enterprise plan
  • Smaller ecosystem compared to established alternatives

Can I use Decodable for free?
Both have a free tier, so you can try either at no cost before committing.
What is Decodable best used for?
Decodable is most often used for streaming postgres change data capture into snowflake or iceberg without running debezium and kafka connect yourself, real-time enrichment and filtering of event streams before they reach an expensive warehouse, a team that already writes flink jobs but does not want to operate the cluster, checkpoint store or upgrades, replacing a fragile set of cron jobs and lambda functions that move data between operational systems. Of those, streaming postgres change data capture into snowflake or iceberg without running debezium and kafka connect yourself and real-time enrichment and filtering of event streams before they reach an expensive warehouse are not what Estuary is typically brought in for.

Answered from the vendors’ own pages

Decodable: What is a credit worth?

0.12 US dollars on On Demand and 0.10 on Enterprise. A small task consumes one credit per hour, medium two, large four.

Estuary: What is included in the free Developer plan?

Developer plan ($0/month) includes 10 GB of data per month and up to 2 connector instances, no credit card required.

Decodable: Is there a free plan?

Yes, up to four concurrent tasks with 24 hour or 10 GB stream retention.

Estuary: How is data pricing calculated on Cloud plan?

Cloud plan charges $0.50 per GB of data moved plus $100/month per connector for the first 6 connectors, then $50/month for additional connectors.

Source
Decodable: Is it really Apache Flink underneath?

Yes, Flink for processing and Debezium for change data capture, both managed by Decodable.

Estuary: What discount is available when adding 6+ connectors?

When using 6 or more connectors, the per-connector cost drops to $50/month from $100/month, saving $50 per additional connector.
