I saw an interesting project for self-hosting.
Umbrel is licensed under the PolyForm Noncommercial 1.0.0 license. TL;DR — You're free to use, fork, modify, and redestribute Umbrel for personal and nonprofit use under the same license. If you're interested in using Umbrel for commercial purposes, such as selling plug-and-play home servers with Umbrel, etc — please reach out to us at email@example.com.
But this seems proprietary/commercial software? OpenWashing? It seems not approved by opensource.org and Debian guidelines.
