Thought people might be interested in something I've just released, Sassy, a Rails app deals with subscriptions and authentication. It's similar to the SaaS RailsKit except it's open source (sorry Ben).
Overview * Subscription management * Recurring billing * Credit card management * User authentication and SSO
Features * No local credit card storage * Automated billing script that should be run nightly * Configurable subscription plans (price/duration) * SSL protection for account creation (and when updating CC info) * Account can have multiple users, interface for adding more * Trial ending mailer * Invoice mailer * Automated notification and retry of failed renewals * Plan upgrade/downgrades * PDF invoices * Forgot password retrieval * OpenID support * Shared secret SSO * Credit card verification * REST API for users and subscriptions
Merry Christmas!
