What is the best alternative of Collabora on Nextcloud for home admins?

Proxying the welcome pop-up page would allow you to customize its content and write your own welcome message without building your own CODE image. In nginx that should work with:

location /browser/*/welcome/welcome.html {
  proxy_pass https://mywebserver.net/collabora_patch/welcome.html;
