FAQ

PM4Py was initially created at Fraunhofer FIT and developed there over several years. Starting in 2024, Fraunhofer FIT entirely outsourced PM4Py to its spin-off Process Intelligence Solutions (PIS), which is now responsible for PM4Py's development, distribution, and licensing.

PM4Py has been released as an open-source version to ensure it reaches a large user base for research, teaching, and open-source purposes. To control the commercial use of PM4Py, the GPLv3 license was deliberately chosen. As mentioned in the table above, there are fee-based software license agreements specifically designed for closed-source applications.

There are a few minor differences between the closed and open-source versions, especially since the open-source versions are released with a delay of approximately half a year.

Please contact us at info@processintelligence.solutions, and we will provide you with an evaluation license specific to this purpose.
