Ask HN: Should I open-source my bootstrapped product?

My product is a scraping orchestration platform (www.yielder.io) About two months ago, after two years of work, I finally got to the point where the product is ready for prime time. Some feedback I got was that I might get more legitimacy / traction / business if I go open-source. Finding customers is hard and for a technical guy the next steps are not obvious, so I started considering it.

Should I open source my product? if so under which license?
