Here's an article in Bitcoin Magazine on this development:
Stripe’s app marketplace was also announced today which will allow companies like OpenNode to create customer user interfaces that will streamline workflows and allow data syncing compatibility between Stripe and its participating partners.
Using Stripe’s open application programmable interface (API), developers can start building apps that will support Stripe integrations. Billing for applications will be fairly straightforward for businesses looking to build on Stripe as the company said Stripe apps do not currently offer billing for apps, however apps can either be free or paid for but companies will need to handle their billing outside of the marketplace at launch.
