I've been using the free version of rambox as a personal account for a number of years.
It started with a need to see my Text Messages, then I started using it to replace broken apps from Thunderbird.
Then I added and then uninstalled windows apps I rarely use like Skype, Teams, etc.
I was trying to add GPT sites, but eventually just ran out of my custom app limit for the free version and I snapped this offer in time.

I love how the GUI is nice and small, and the fact that I can load far more apps on Rambox than its competitors, and the ram used is still lower (hence the name).
I also appreciate the cookie sandboxing features so then I can load multiple accounts of apps such as google suite.
My fav feature is the workspace that lets me to load multiple apps in one window, so I can just see the weather and access my call notes app quickly, whilst also seeing the rambox blog page to notice updates.

I was also impressed with the speed of support replies.

I want rambox to stick around long term, it's incredibly valuable!
