Install Parsec on your home workstation and your portable laptop. With a stable Wi-Fi connection, you can edit massive UE5 worlds on a thin fanless laptop with zero lag. Cloud Workstations (AWS, Azure, Paperspace)
First, the bad news:
: A standard UE5 installation can exceed 50GB–100GB. Some users have "stripped" the engine by removing unneeded plugins or assets to reduce the footprint below 10GB for extreme portability. Portable Alternatives
I ran the editor from a Samsung T7 Shield (USB 3.2 Gen 2) on three different PCs (laptop, desktop, and a friend’s gaming rig). No installation, no admin rights required. For freelancers, students, or devs hopping between workstations, this is a lifesaver.
Here is the brutal truth: When you compile shaders or build lighting, even the most efficient laptop draws 150+ watts.

A free, open-source alternative that provides ultra-low latency streaming over local networks or the internet. Best Practices for Mobile Workflows
Do you prefer an (like an external drive) or a cloud/remote solution ?
A high-performance laptop for UE5 development can cost between $1,500 and $3,000+. For those on a tighter budget, a less powerful machine can be improved by using a via a Thunderbolt 3 or 4 connection. This adds a powerful desktop-class GPU to an otherwise modest laptop but is a significant extra investment and less portable.
