Jappe OS is a linux operating system made by the jappe OS team. You can download the .iso file for free and use Jappe OS on your computer if you want. Installation tutorials can be found here, in the future. The desktop environment is written in flutter and the source code is available here on the github, where all releases are found, and issues/bugs can be reported too.
Jappe os desktop is now in development by jappe studios, so, only alpha testers and developers have access to the desktop environment.
The jappe os discord has a devlog channel where you can see new things added to Jappe os. Discord link: https://discord.gg/dRtU4HR
