The 'pay' gem describes itself as a "payments engine for Ruby on Rails".

Currently it directly integrates with Stripe, Braintree and Paddle.

Further the gem is used as part of the Jumpstart app which is a Ruby-on-Rails SaaS template used by many Rails projects.

Despite using the abstraction of the pay gem, developer are still locked into the ecosystem of the payment "platform" they use, most commonly Stripe Payments with Stripe Billing.

Extend the Pay gem so that Lago can be used as an integrated option for use with Jumpstart template based apps as well as others.

Core contributor Chris from GoRails, who maintains the Pay gem and Jumpstart, is supportive of this integration if it can be done.
