Chrome Web Store allows you to upload apps up to 10 MB in size last I checked, and when I asked about it they said they'd be expanding that or ditching the limit altogether eventually which may be the case now.
GitHub offers fantastic free hosting. No bandwidth limits, no storage limits, nothing, for free. But you have to use Git (which isn't too hard.) 4kg: Prototype is hosted on GitHub and the Chrome Web Store and I haven't had to pay a cent for hosting.
Well right now I have a prototype that I'm hosting via dropbox. What I'd like to do it to move over to a platform where I could use ads and drop some analytics code into the page. While I haven't seen anything in a TOS about this I assume it's not kosher with Dropbox. I also don't want to lose my precise 9GB of Dropbox if something happens or my app gets hammered.
I don't mind losing a GitHub account but are there any barriers to monetizing? Github is open source friendly so I assume they'd frown at that. One of the goals with my project is $0 startup costs which means I'd like to find a way to make $5 for a Chrome App Store license before I put my app there. I also would rather not beg for money on Kickstarter.
