With Mini Apps developers can use JavaScript to create infinitely flexible interfaces that can be launched right inside Telegram — and can completely replace any website.

Like bots, Mini Apps support seamless authorization, payments via third-party payment providers (with Google Pay and Apple Pay out of the box), delivering tailored push notifications to users, and much more.

To see a Mini App in action, try our sample @DurgerKingBot.
