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.; Node-RED the Node-RED editor ships unsecured: anyone who can reach its IP address can open the editor and deploy changes until adminAuth is configured
  • They diverge on capability: Flowable covers BPMN 2.0 engine, Node-RED covers Visual Editor.
  • 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.

Node-RED

  • The Node-RED editor ships unsecured: anyone who can reach its IP address can open the editor and deploy changes until adminAuth is configured
  • HTTPS is off by default and must be enabled through the https setting
  • HTTP endpoints and dashboards exposed by flows are unauthenticated unless httpNodeAuth is configured separately
  • All three security layers are optional additions the administrator must implement by editing the settings file

Questions people ask

Is Flowable or Node-RED better?
Neither clearly leads. Flowable starts at Free and Node-RED at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Flowable or Node-RED?
Flowable starts at Free and Node-RED at Free.
Does Flowable or Node-RED run on more platforms?
Flowable runs on Linux, Windows, Docker, Kubernetes, Cloud. Node-RED runs on Node.js, Docker, Cloud, Edge devices.
Can I use Flowable for free?
Both have a free tier, so you can try either at no cost before committing.
What is Flowable best used for?
Flowable is most often used for an insurer automating claims handling where each case follows a different path and bpmn alone cannot express it, a bank embedding process orchestration inside an existing spring boot estate rather than buying a separate platform, a team leaving activiti or jbpm that wants the same api family with active commercial maintenance, a regulated organisation needing complete process history and decision table audit trails for supervisors. Of those, an insurer automating claims handling where each case follows a different path and bpmn alone cannot express it and a bank embedding process orchestration inside an existing spring boot estate rather than buying a separate platform are not what Node-RED is typically brought in for.
What can Flowable do that Node-RED cannot?
Flowable covers BPMN 2.0 engine, CMMN case management, DMN decision tables, Spring Boot integration. Node-RED covers Visual Editor, Flow-Based Programming, Extensible, HTTP Integration.

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.

Node-RED: Is Node-RED free?

Yes, Node-RED is completely free and open source. It is available under the MIT License through GitHub and npm package manager. The project is maintained by the OpenJS Foundation.

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.

Node-RED: Does Node-RED offer commercial support?

Node-RED itself is free and community-supported. FlowFuse, Inc. was founded in 2021 as a separate commercial entity offering enterprise support and a professional platform for Node-RED deployment, but FlowFuse is not Node-RED.

Source
Flowable: What does Flowable Enterprise cost?

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

Node-RED: What is Node-RED pricing model?

Node-RED has no pricing model. It is completely free open source software. Commercial support and hosting options may be available separately through third-party providers like FlowFuse, but the core software is not sold.

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.
