Don't be afraid of that, you should be happy to have that as a service and encourage some people to do that if they want. I think 98% of the people will end up exporting their code and not using the service. It will be free. But it will make your service famous and the few people who do pay will be loyal. You can't do everything well. If the main thing you do is an MVP producing service, that is great. Add on to that. You might end up adding a whole different set of services such as paying for user feedback or user analysis or something else. Edit: Just to be clear - I don't mean to advise you on what the service should or should not be. I just mean that it will evolve in ways you may not anticipate. The market will pick and choose what it wants. The things you initially think are small might turn out to be more profitable than the things you initially think are big.
