Set up testers, contributors and students for success with pre-built templates that they can spin up in the cloud with a few clicks.
As Trainers / Maintainers, you can create a Drupal "QuickStart" exactly how you want people to run it, with all the modules, data, themes... even bring in code from different repos / origins.
Students, testers and contributors can then spin up an exact copy of your pre-defined environment in the cloud, pre-built with tools like Cloud-IDE (Browser-based VS Code) and PhpMyAdmin.
Although the cloud based dev environments are ephemeral, the working environments can be entirely saved to the repo so they can be recreated at any time.
You can do all of this using the Free Community Edition of DevPanel.
