Is there some good cross platform web application development software out there (something that will run on OS X and/or Win/*nix)? A group of us were considering working with Dynamo but due to cost and the fact that it is a pet project, we need to move to something else.
I know little to nothing about web app development, so I am asking here. The first suggestion that came up was
Resin, which is free and seems good. I can lend some hardware that can run OS X, which will help only if we can program or run on OSX.
Can any of you here enlighten me?
