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.; Hasura active model definition: model/command accessed more than 1,000 times monthly
  • They diverge on capability: Decodable covers Managed Flink, Hasura covers GraphQL API.
  • 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.

Hasura

  • Active model definition: model/command accessed more than 1,000 times monthly
  • Private DDN requires Base or Advanced plan
