Right now you need to be using Stripe or Braintree to use ChartMogul and we’re working on support for Chargify and Recurly.
You can signup for an invite on ChartMogul.com, we’ll be sending out batches of invites daily.
We won’t be running a completely open beta, this is so we can keep performance stable for existing users and scale the system in a controlled way.
If you want to get access right away just tweet something @ChartMogul and we’ll be sure to oblige you.
Please send any feedback or questions to support@chartmogul.com
