I suppose "brogrammers" might be a target audience, but the concept of the tool itself is pretty good for just about anyone. Shame about the name.
Just because it starts with the same three letters doesn't mean anything. As already stated in many other comments, "bro" is also, and more commonly, used as a substitute for other colloquial words such as "man", "dude", "guys", and is frequently gender neutral.
These niggling complaints of offense where none was intended is indeed getting old. The author's intent is what actually matters, not how someone else interprets it. A reader gets to choose whether to be offended by a word or not, he doesn't get to choose the author's intent.
