Is go daddy a good hosting option if I want to start small and scale to hundreds of thousands of users?

Godaddy is pain for developers and technical people, as it is set up for simple things. You can use any good hosting companies or any cloud servers. But if you need to talk to a human godaddy is a good option. Scalability will not be an issue with Godaddy, as they can sell you any infrastructure when you grow bigger.

Hello

GoDaddy is not great and if your a developer I would go for a different option as go-daddy maybe restricted for you.

GoDaddy is definitely not the best option for hosting, not even for keeping your domain!

I'd recommend to get a reputable hosting company, preferrable not using a shared hosting. You can check out Google Cloud Platform or Amazon Web Services that will scale up with your needs.

Godaddy would not be my first option of choice, they have a lot of associated services that can help you grow, like the smartline feature, however, on the functionality and design sides, they tend to fall short, at least in my opinion.
I would recommend to look at wix.com. they offer plenty of personalization, easy integration with 3rd party softwares, usefull apps and much more.
