It's not even close to being accurate. StackMob has multiple official partnerships with companies on that list that include full integrations, not just compatibility, but you only see one line of integration to Heroku. It would take 30 seconds worth of research to show how inaccurate that chart is.
Wow, that is a very similar announcement from a very similar product.
Superficially it seems that Parse and Stackmob are executing on the same vision, at roughly the same velocity. Yet Parse seems to get more publicity these days. Is it just that they'r e better at engineering hype and projecting the image of success, or is it something else?
