OPINION: How would you set up your project to build on a laptop & a PC?

Just curious how other people would set up their servers, targets etc if they wanted to be able to interchange (possibly multiple times throughout the day) from a desktop PC and laptop/notebook?

Currently I’m just working on my PC locally and with ‘localhost’ MAMP sever and postgresql installed on my PC.

I want the versatility of switching to my laptop, but not sure the best way to set it up.

I also have my web host company I could add a random add-on domain for testing etc. If that was easier.

Thanks in advance for your thoughts.

Cheers
Phil
