You can generate builds for desktop operating systems and the web with the basic license. With the web builds, you can host them anywhere on the web since they're static files. But a lot of the community uses Itch.io to share their games.

I'm actively working on an interactive showcase of DragonRuby games here: https://dragonridersunite.itch.io/dragon-os

Or you can browse games made with it here: https://itch.io/games/made-with-dragonruby-gtk
