Just to clarify, this requires both the client and the debugging script to be running 3.14? So I cannot have a script running an older version of Python but use

  Yes

  So Python 3.14 introduces this functionality. The process you want to debug needs to be on at least Python 3.14. If you want to "just" use sys.remote_exec, you will need to use that from a matching Python version. If you dive into the implementation (check out the PEP), you could most definitely write a C or Rust program that implements remote_exec and "does the thing". The protocol is basically "tell the program to read a python script from this file". That python script will be executed in the running program's environment, but you don't need for the software on the other side to be a python program! sys.remote_exec itself only targets same Python versions though.

  You can check out pyrasite[0], which does the same and works in theoretically all relevant Python versions, without need to version match. [0] https://pyrasite.readthedocs.io https://pyrasite.readthedocs.io
