tiun. - Auth, billing, and payments for AI builders

One system for auth, payments, customer data, and analytics. One command to install. Launch a paid product the same day you start building.

Huge thank you to everyone who supported tiun!

Whether you upvoted, commented, shared the launch, tried the product, or gave us feedback.

Getting tiun in front of thousands of founders and builders and finishing #2 for the entire month means a lot to us.

We're still early, and we're just getting started.

Yesterday, tiun launched on Product Hunt and finished with 527 upvotes and 106 comments, making us #1 Product of the Day.

For our first launch, this feels incredible, Thank you!

Do you actually care how many tools are running behind your AI app?

Are you fine connecting separate tools for auth, payments, billing, taxes, and analytics? Or do you prefer one system handling most of it? Not just because setup takes time, but because every extra service means another dashboard, integration, and possible failure. Asking this cause I think builders should spend more time shipping the product, as long as the backend stays flexible and reliable. But this brings us to another question, when does convenience become lock-in?

We built tiun because launching an AI product should not require five tools and a webhook nightmare

Hey everyone,

We have been building tiun: one backend for authentication, payments, customer data, and analytics.

No one should be stitching together five tools just to launch and monetize a product

It's 2026, and building an app has never been faster. But the moment you need authentication, payments, subscriptions, usage-based billing, customer data, and analytics, everything becomes complicated again.

You connect one tool for users, another for payments, another for product data, and then have to keep all of them in sync. This shouldn't be the part that slows builders down.

That's why we're building tiun. One backend for AI and SaaS builders that brings authentication, payments, customer data, and analytics into one system.

You can create different pricing models, charge based on usage, generate invoices, manage customers, and understand how people use your product without maintaining a fragmented stack.
