I've started using workspaces in Edge to quickly access the sites I need for my tasks. However, it can sometimes happen that I have to have a few workspaces open at the same time. This can drain RAM in a heartbeat, even on my system with 64GB.

Rambox offers a comprehensive solution. Just like in Edge, I can have different workspaces with custom apps/sites. The difference is that after a few minutes of inactivity, the apps in all Rambox workspaces hibernate, freeing up more memory than Edge.

I am very glad I got this.
