Hello, I am José from France
Retired, I found Umbrel.com on Product Hunt
With some practices in IT, I focus on users and business development :).
I could be interested in Umbrel for personal use (RPI or Contabo VPS) and why not to recommend it to Small business :).
Currently, I use YUNOHOST.org.
Have a nice time :).
José Relland, France.
Feel free to contact in French.
