How it works

The core flow

tiun replaces the commercial backend you'd normally build yourself. Instead of stitching together a payment provider, an auth system, session management, and access control — you create a product in the tiun dashboard, and the SDK handles everything from checkout to access.

The flow is simple: you define a product (a subscription plan or a time-based rate), then call checkout (subscriptions) or start (time-based) from your frontend. tiun takes over — it shows the payment UI, authenticates the user, processes the payment, and manages the session. Your app receives an event when access is granted, and you show the content.

There's no backend to build. No webhook endpoints to maintain. No user tables to manage. tiun is the layer between your frontend and all the commercial infrastructure — payments, identity, access control, customer data. You write product logic; tiun handles the commercial stack.
