Is Product Hunt a good place to post an open-source software launch?

Hi, I'm working on an open-source project for mobile developers and I'm curious: is Product Hunt a good place to launch?

We've met several folks who are only interested in commercial apps, so I have no idea where to introduce our open-source product to the public.

I'm specifically looking for people who are building mobile apps and want to boost their user engagement.

Thanks in advance.
