Sign-in without forms
Telegram passes the user’s profile to the app with a signature, and the server verifies it on every request. No passwords and no sign-up screens.
Telegram Mini App development
A Telegram Mini App is a web app that opens inside Telegram: the user is already signed in, there is nothing to install, and payment takes a couple of taps. I build Mini Apps together with the bot and the backend behind them. You can read the code of one right now: TON Access Pass sells access to a private channel for TON and is published on GitHub with its tests.

What a Mini App can do for your business
Payments in two taps
Telegram Stars for digital goods, TON through TON Connect, or a payment provider connected to your bot.
Catalogs and bookings
A store, a menu or a booking calendar, with order updates sent to the user in the bot chat.
Subscriptions and paid access
Access to a private channel or course that is granted and revoked automatically, as in TON Access Pass.
Native look
The app follows the user’s Telegram theme and uses the native main button and haptics, so it feels like part of Telegram.
Bot and admin tools
The bot sends updates and reminders, and the owner manages orders and settings without a separate dashboard.
How I build Mini Apps
A Mini App is only as good as the bot and the server behind it, so I design all three together: the scenario in the chat, the screens in the app and the API that checks every request. The server never trusts data from the browser, only what Telegram has signed.
The front end is plain TypeScript or React and is kept light, so it opens fast on mobile data. TON Access Pass loads a 12 KB app first and fetches the 520 KB TON Connect library afterwards, so the subscription status shows up right away.
Small Mini Apps can be quick: one client got a working Mini App in less than a day. Larger ones are delivered in stages with a demo every week, and the code and server access stay with you.

FAQ
How much does a Telegram Mini App cost?
From $1,000 for a Mini App with a few screens, sign-in through Telegram and a backend. Payments, admin tools and smart contracts add to the scope. The quote is fixed in the contract after a free call.
What is the difference between a bot and a Mini App?
A bot talks to the user in the chat with messages and buttons. A Mini App opens a full interface inside Telegram: catalogs, forms, calendars. They usually work together: the bot brings people in and sends updates, and the Mini App handles the screens.
Can users pay inside the Mini App?
Yes. Digital goods in Telegram are sold for Telegram Stars, crypto payments go through TON Connect, and physical goods can use a payment provider connected to the bot.
Can I see a Mini App you have built?
Yes. TON Access Pass is open source: the code, the tests, a demo recording and the contract deployed to testnet are on GitHub.
Do you build the backend too?
Yes. The bot, the API, the database and the deployment on your server are part of the job, and you get the code and the access.
Who will build the Mini App?
I will, personally, from the scenario to the launch. You talk directly to the developer.
