What diagnostic software?

[TahoeLT10]

I am thinking about upgrading my old 2010 Tahoe to 2021 Yukon or 2021 Suburban. What diagnostic software works to the same level of GDS2 and Tech2 on these newer vehicle? I currently mainly use Tech2 on my Tahoe with VXDIAG Nano and it works great, but can't find anything that is equal for 2021+ models as VXDiag seem to only provide GDS2 support for up 2020. TIA!

probably isn't going to be one, GM is going with ULTIFI and is going to make many features subscription based, they have already started with 3yrs onstar required monthly or paid in lump sum.
If you want to be able to modify and diagnose your vehicle beyond obdII then I would not buy anything newer than 2020
they are going to allow 3rd party "apps" only
updates will be pushed over the air so any bugs or security issue's found will be updated and fixed.
unless some right to repair laws get passed everyone is probably screwed
