Telegram Mini Apps Development Services

Telegram Mini Apps are web applications that open inside Telegram, and we develop them end to end: specification, UI design, the web app, the bot and backend, payments, testing, launch and support after release.

In short

Typical uses: online stores and catalogues, bookings, loyalty programmes, games, crypto wallets and services.
Users open the app from a bot, a channel or a link, with no install from an app store.
Payments use Telegram Stars for digital goods or connected payment providers for physical goods where available.
An MVP takes up to 15 business days after the specification is approved and materials are received.
We deliver source code and access to your bot and servers.

What Telegram Mini App development includes

Specification. User flows, screens, bot commands, integrations and admin functions.
UI/UX design. Interface that adapts to Telegram light and dark themes and to phone screens.
Front end. Web app built with a modern JavaScript framework and the Telegram Mini Apps SDK.
Bot and backend. Bot through BotFather, server side, database, admin panel and API.
Payments. Telegram Stars for digital goods and services; payment providers for physical goods where Telegram supports them.
Integrations. CRM, online store, booking systems, analytics; TON wallet connection for crypto projects.
Testing. Checks on iOS, Android and desktop Telegram clients.
Launch and support. Deployment, bot settings, updates and new features.

Mini App, bot or mobile app?

A bot is enough when the flow is a short dialogue: questions, notifications, simple orders. A Mini App suits richer interfaces such as catalogues, forms, maps or games, and still lives inside Telegram, so users need no installation. A mobile app makes sense when you need deep device features or an audience outside Telegram. For many businesses in Ukraine and Eastern Europe, where the audience already uses Telegram daily, a Mini App is a quick way to test a product before a full app.

How we build a Telegram Mini App

Brief and specification. We define users, features and integrations.
Design. We design screens for Telegram clients.
Development. We build the web app, bot and backend.
Testing. We test on phones and desktop clients.
Launch. We deploy and connect the bot.
Support and growth. We fix, update and add features.

How we build a Telegram Mini App

How long does it take to develop a Telegram Mini App?

In our experience, a focused MVP such as a catalogue with orders or a booking app takes up to 15 business days after the specification is approved. Games, crypto features and complex integrations take longer and are released in stages.

The timeline depends on the number of screens and roles, payment and third-party integrations, and on how quickly designs and test builds are approved.

What affects the cost

We estimate after the brief. The price depends on:

number of screens, roles and features;
payments and integrations with CRM, store or booking systems;
game mechanics or crypto functions;
admin panel and reporting;
support after launch.

What we need from you

A description of the idea, the audience and the main actions in the app.
Access to your Telegram bot or consent to create one for your company.
Access to systems to integrate.
A person who approves stages.

What you get

At the end of the project you own the app and the data:

working Mini App connected to your bot;
source code and access to servers;
analytics of opens and key actions;
instructions for the admin panel.

Why a Mini App needs a team under contract

Mini Apps combine a website, a bot and a backend. Problems we see:

the bot is registered to the developer's personal account;
no server-side validation of Telegram user data, which opens the app to abuse;
payments set up against Telegram rules and blocked;
no support after launch when Telegram changes its API.

Working with a Kyiv team remotely

We work remotely with companies in the UK, the EU and North America: video calls, email, Telegram or WhatsApp, and shared documents for plans and reports. Kyiv is on UTC+2 (UTC+3 in summer), so our working day covers most of the UK and EU business day and the morning on the US East Coast. You get one project manager who is responsible for the timeline.
