A Telegram Mini App is an app inside the messenger: customers open your shop, booking or account in one tap with no install or sign-up. We build Mini Apps with catalogues, carts, payments, bot notifications, multilingual UI and an admin panel.
Mini Apps share one core with your website and PWA, so every update ships everywhere at once. DeusCode is headquartered in Almaty, Kazakhstan, part of the Infinity Core Technology holding in Dubai, with representative offices in Russia and France. We work with clients across Kazakhstan, Central Asia, Europe and the Middle East.
FAQ
▸Does a Mini App replace a native app?
For shops, services, booking and games — yes. If you need heavy 3D, AR or system APIs — go native.
▸What about growth?
We wire up bot notifications, broadcasts, referral programs. Telegram's growth loop is faster than app stores.
▸User security?
We verify initData signature server-side, encrypt traffic, restrict sensitive data.
▸What if Telegram gets blocked?
We build a multi-channel architecture — the logic also runs as a web version outside Telegram. Business functions stay intact.
