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.; Tasmota tasmota only runs on Espressif ESP8266, ESP8285, ESP32, ESP32-S and ESP32-C3 chipsets, so devices built on other silicon cannot use it
  • They diverge on capability: Flowable covers BPMN 2.0 engine, Tasmota covers Local Control.
  • 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.

Tasmota

  • Tasmota only runs on Espressif ESP8266, ESP8285, ESP32, ESP32-S and ESP32-C3 chipsets, so devices built on other silicon cannot use it
  • Initial installation requires opening the device, bridging GPIO0 to ground during boot and using a 3.3V serial programmer; a 5V programmer damages the chip
  • The ESP chip needs at least 150mA at 3.3V, so an underpowered supply causes flashing and stability failures
  • The Wi-Fi setup access point stays active for only 3 minutes, after which the device must be power cycled to try again
  • The Power Cycle Recovery feature can reset a device to firmware defaults where mains power fluctuates, and the docs advise disabling it in that case

Questions people ask

Is Flowable or Tasmota better?
Neither clearly leads. Flowable starts at Free and Tasmota at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Flowable or Tasmota?
Flowable starts at Free and Tasmota at Free.
Does Flowable or Tasmota run on more platforms?
Flowable runs on Linux, Windows, Docker, Kubernetes, Cloud. Tasmota runs on ESP8266, ESP32, Compatible 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 Tasmota is typically brought in for.

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.

Tasmota: What is the cost of Tasmota?

Tasmota is completely free as open-source firmware for ESP devices. Source code is available on GitHub, and the project accepts donations for continued development.

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.

Tasmota: Can Tasmota be modified and redistributed?

Yes, Tasmota is open-source software allowing users to access, compile, modify, and redistribute builds according to the project LICENSE.

Source
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.
