This makes me think of pgModeller: "pgModeler is open-source software, and you can get its source code anytime if you want to compile it by yourself. As a convenience, we provide compiled binary packages at a really fair price. Also, if you're interested in evaluating a binary package, you can get a demo copy before proceeding with the purchase." (quoted from from [1]) It's open source (GPL 3). They give build instructions, but it's quite strenuous to build[2].
