Hi there guys. I am creating a site for a client and have two options for the backend: GravCMS and Meteor. The site will consist of a few static pages, a blog (maybe) and a shopping cart with paypal, stripe and cc payment options. The best option that is PCI compliant is BrainTree by PayPal. Meteor already has that as one of the addons. I was wondering if there is anything similar with GravCMS?
