Your pricing page is tucked away at the bottom. It's one of the first pages I go to, and hiding it like that makes me think you're trying to trick me.
At this point I'm totally burnt by commiting my data to free/freemium saas products that end up shutting down a year later, just want to pay for good service and have a bit of hope that it stays afloat.
Jokes aside, i'm of the opinion I'd allow free use with severe scale limitations - more or less what bitbucket did/does with private repos.
