LittleDarwin vs MutPy
Both stand on mutation testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Linux
LittleDarwin offers configurable mutation analysis for Java projects, with filters, build settings, and reports. It is a Linux option for teams comfortable installing and running a Python module.

MutPy provides mutation controls, coverage analysis, and reports for evaluating Python tests. Its listed release is old, and teams using pytest should account for its experimental status.
