Yes.

I don't mean literally $4/hr, but just any developer whose distinguishing feature is being cheaper than most other developers.

I thought that was Fiverr's brand.

That's not their brand, at least not in the past 5 or so years. I've had significant success with Fiverr, many of which are not the cheapest. Certainly you can find the cheapest if that's what you want, but that's on any freelance platform.
