The short version

  • Each has a real cost: Flowable the open source engine is genuinely usable but ships without the modelling studio, work application and admin console, so an open source deployment means building your own user interfaces before anyone can use it.; GraphQL Playground apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead
  • They diverge on capability: Flowable covers BPMN 2.0 engine, GraphQL Playground covers Query building.
  • 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.

Flowable

  • The open source engine is genuinely usable but ships without the modelling studio, work application and admin console, so an open source deployment means building your own user interfaces before anyone can use it.
  • It expects Java engineering capacity; teams looking for a business-user low-code automation tool will find the modelling and deployment cycle far too technical.
  • Enterprise pricing is not published and is quoted per deployment, leaving buyers without a benchmark against Camunda or IBM alternatives.
  • The Activiti fork left three engines with related APIs and overlapping documentation in circulation, and search results routinely return advice for the wrong one.
  • Flowable AG is a small Swiss company relative to its competitors, so the partner network, training market and pool of engineers with production experience are all limited outside Europe.

GraphQL Playground

  • Apollo's own documentation states GraphQL Playground is officially retired and no longer recommended, directing users to Apollo Sandbox instead

Answered from the vendors’ own pages

Flowable: Is Flowable open source?

Yes, the BPMN, CMMN and DMN engines are Apache 2.0. The modelling studio and enterprise applications are commercial.

GraphQL Playground: Is GraphQL Playground free to use?

GraphQL Playground is a testing tool for Apollo Server and is free to use as part of the Apollo Server documentation. However, the broader Apollo GraphQL platform has various paid tiers available for production use.

Source
Flowable: How does it relate to Activiti and jBPM?

The same core developers built jBPM, then Activiti, then forked Activiti in 2016 to create Flowable.

GraphQL Playground: Is GraphQL Playground part of a paid product?

GraphQL Playground is a testing tool within the Apollo ecosystem. While Playground itself is free, Apollo offers paid tiers starting at $5 per million requests for the Developer tier, with Standard and Enterprise plans available at custom pricing.

Source
Flowable: What does Flowable Enterprise cost?

Nothing is published. It is quoted per deployment by the vendor.

GraphQL Playground: What is the cost structure for Apollo GraphQL's paid plans?

Apollo uses volume-based tiered pricing for requests: first 250M operations cost $5.00 per million plus $2.00 for performance add-on; next 750M operations are $4.25 per million plus $1.50 add-on; additional tiers scale down to $3.00 per million plus $0.50 add-on for operations over 5 billion.

Source
Flowable: Why choose it over Camunda?

CMMN case management is a first-class engine, which matters when work is exception-driven rather than a fixed sequence.
