Can I say something like "what can I do in your website"?
I know "on a website" is more commonly used, but is it ungrammatical to use "in a website"?

Your example is much better expressed with "on". Still, if you do a Google search for "in this|a|the website" you'll find many examples.
In short, as is usually the case with our wonderful prepositions, it depends on the context.
"In a website" or "on a website"?
