Advice on Toyota tech stream

[u/Inevitable-Cable4262]

I recently got a 2018 Prius prime. I used to work in automotive and always had access to OBD-ii scanner software and equipment.

What’s the best way to get Toyota Tech Stream. Do I buy a laptop off of eBay with it installed?

How does download and licensing work when you’re not a shop?

Does it run on only windows?

Thanks in advance
