What can I host?
You can host any content on your Gandi Simple Hosting instance as long as it is legal and within the limit of the resources available to you.
Of course, some content will only work on a type of instance that is dedicated to the type of content. For example, if you try to host a website built in ASP on a PHP/MySQL instance, it will not work as the programming language is not the same.
Also, you should keep in mind the pageview limit of your instance size.
Our Simple Hosting Tutorials provide good examples of the tools and applications that you can host.
