The short version

  • Only Flowable has a free tier, so it costs nothing to try first.
  • Each has a real cost: Appian cost multiplies on three axes at once, users, apps and month, so deploying several apps to overlapping user populations produces a bill that is not obvious from any single per-user headline figure.; 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.
  • They diverge on capability: Appian covers Low-code process designer, Flowable covers BPMN 2.0 engine.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Appian

  • A regulated enterprise (financial services, government, insurance) automating case management processes that need a full audit trailnot Flowable
  • A company deploying RPA bots alongside low-code apps and wanting both in one licensed platformnot Flowable
  • An organisation whose process data volume is large enough that the Standard tier's 4 million row cap is a real constraint worth planning fornot Flowable
  • A business wanting embedded AI actions inside workflow steps rather than bolted on separatelynot Flowable

Flowable

  • An insurer automating claims handling where each case follows a different path and BPMN alone cannot express itnot Appian
  • A bank embedding process orchestration inside an existing Spring Boot estate rather than buying a separate platformnot Appian
  • A team leaving Activiti or jBPM that wants the same API family with active commercial maintenancenot Appian
  • A regulated organisation needing complete process history and decision table audit trails for supervisorsnot Appian

Where each one falls short

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

Appian

  • Cost multiplies on three axes at once, users, apps and month, so deploying several apps to overlapping user populations produces a bill that is not obvious from any single per-user headline figure.
  • Each tier has hard caps on data rows, RPA bots and monthly AI actions, so a workload can force a tier upgrade purely from data or automation volume growth, independent of user count.
  • No dollar figures are published anywhere on Appian's own site; every real price point comes from a sales negotiation, making early-stage budget comparison against OutSystems or Mendix difficult.
  • The platform's strength in process orchestration and case management is less useful for teams that mainly want simple departmental data apps, where the pricing and capability are overkill.
  • Exceeding the 200,000 (Standard) or 1,000,000 (Premium) monthly AI action allowance requires a renegotiation, so AI-heavy workflows carry real usage risk beyond the base subscription.

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.

Answered from the vendors’ own pages

Appian: Does Appian publish its prices?

No dollar figures are public. It discloses the pricing mechanism, per user per app per month across three tiers, but actual rates are negotiated.

Flowable: Is Flowable open source?

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

Appian: What happens if we exceed the data row cap?

Exceeding a tier's data row, RPA bot or AI action cap requires upgrading to the next tier or negotiating an add-on, regardless of user count.

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.

Appian: Is Appian a general app builder like OutSystems?

It can build general apps but is oriented more toward process automation and case management, with RPA and AI embedded as core features.

Flowable: What does Flowable Enterprise cost?

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

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.
