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.; Hevo Data billed on events ingested rather than on connectors or seats, so the bill tracks how chatty the sources are
  • They diverge on capability: Decodable covers Managed Flink, Hevo Data covers No-code pipeline builder.
  • 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.

Hevo Data

  • Billed on events ingested rather than on connectors or seats, so the bill tracks how chatty the sources are
  • The free plan allows 1M events a month and the Starter plan starts at $265 a month billed annually
  • Event volume is a priced tier inside each plan, at 5M, 20M or 50M on Starter
  • Usage above the plan quota is charged as on demand on top of the subscription, and the overage rate is not published anywhere on the pricing page
  • Paying monthly rather than annually raises Starter from $265 to $299
