I thought there was no pricing available until I came back and saw this comment, would not sign up for "freemium".
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.
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.
