The choice in practice
Choose the workbench for the connected process.
Use the open foundations directly, or use PathLAB Studio to connect authoring, execution, review and experiments in one working environment.
See how PathLAB works ↗What can I use for free?
The open-source runtime and Pathproof, plus limited working access to PathLAB. You can experience the workflow before choosing the complete paid workbench.
Why choose the paid workbench?
To work through the whole loop in one place: author the workflow, inspect a run, handle a human gate, review its record and compare the next version. The controls and evidence stay connected while you work.
Does someone need a licence to verify my receipt?
No. Pathproof verification is independent of a paid PathLAB key. A recipient can check the proof material you provide without purchasing the workbench.
Is enterprise licensing a consulting package?
No. It is licensing for the software. John's independent workflow-systems service has its own scope and engagement on the Services page.
How do I discuss licence terms?
Use the PathLAB or enterprise licensing enquiry above and describe your intended use. Each enquiry is about the product, not a booking for consulting.

Need a system built for your business?
Custom systems are a separate service, not part of a software licence.
