What is tiun

The commercial backend for SaaS, AI and digital products.

One system for authentication, payments, and customer data. No backend to build. No payment UI to design. Integrate once and go live.

Why tiun

• No backend required — tiun is the backend. Authentication, billing, and access control are handled for you.
• No UI to design — Checkout, login, and paywall overlays are built in and fully managed.
• One SDK, every pricing model — Subscriptions, one-time purchases, and time-based billing through the same integration.
• Go live in a day — Install the SDK, create a product in the dashboard, and you're ready to charge.
