Telegram Mini App and bot development
Mini apps that open right in the chat: no install, no sign-up, no passwords. Stores, games, services and Web3 products — this is the area where we have the most case studies.

§ 06FAQ
Asked before kickoff
01How is a Mini App different from a regular bot?
A bot talks in messages and buttons. A Mini App is a full interface inside Telegram: catalogues, forms, charts, games. They usually work as a pair — the bot launches the app and sends notifications.
02Does a mini app have to go through the App Store or Google Play?
No. The app opens from a link or a chat button and works the same on iOS, Android and desktop Telegram. Updates go live immediately, with no store review.
03Can it take payments?
Yes. A mini app can take payments right inside Telegram. We choose the method for your product and jurisdiction.
04Do you build mini apps for VK?
Yes. Our portfolio includes a game client that runs in both Telegram and VK.
05How much does a Telegram Mini App cost?
Projects start at $500. A simple store and a game with an economy and a blockchain are tasks of different scale, so you get a staged estimate after discovery.
