How do you communicate to users that your product is "simple"?

I've been working on this for over a year, and I'm really excited to finally push this out to a larger audience.

Something I've noticed pretty quickly is what I consider to be a "simple" idea is not as easy to translate to others. My product seems too simple, and I even made that a tag line. But I'm wondering if I'm missing something obvious.

I'd love some feedback on whether I'm really communicating the idea well enough. My product allows you to deploy APIs within minutes. Any thoughts on how I could improve my message?
