CorsegoSaaS is a Ruby on Rails 6 multitenancy boilerplate designed to facilitate the rapid development of scalable, multi-tenant SaaS applications. It offers comprehensive features including user authentication with email, Google, and GitHub logins, and the ability to connect multiple social accounts to a single user. The platform supports complete row-based multitenancy, allowing users to create multiple tenants, such as organizations or teams, switch between them, invite members, and manage access rights. Authorization is managed through customizable roles (admin, editor, viewer), with plan-based restrictions enabling the creation of custom pricing plans and limitations, such as maximum members per tenant. Billing and subscription functionalities are integrated via a custom engine with Stripe support, encompassing subscriptions and one-time payments. A simple super admin panel facilitates the management of users, tenants, plans, subscriptions, and charges.
