Mini App
development
Stores, services and fintech products inside Telegram. We design the interface, build the backend and connect payments and business systems — from your first user journey to launch.
No specification needed. Start with your idea and the problem you want to solve.
01 / A PRODUCT INSIDE TELEGRAM
When a Mini App
makes sense
A Telegram Mini App is a web application that opens inside Telegram. It fits journeys that need a visual interface: browsing a catalogue, managing an account, booking a service or working with assets.
Commerce and booking
A catalogue, cart, booking flow and order status. A fit for businesses already communicating with customers on Telegram.
Telegram store developmentCommunities and subscriptions
Member accounts, content access, loyalty and referral flows. Build the first release around a clear reason to return.
VPN service with Telegram subscriptionsFintech and Web3
Wallets, asset operations and external services. Access controls, security and platform requirements need their own place in the scope.
Explore Telegram crypto wallet developmentIf notifications and a few commands solve the problem, start with a bot. Add a Mini App when a visual interface makes the task easier.
02 / YOUR FIRST RELEASE
One complete journey.
A focused MVP.
Start with a user journey that works from beginning to end. This is a starting point for scoping, not a mandatory feature bundle.
-
Sign-in and profile
Telegram authentication, server-side validation, roles and permissions.
-
The core journey
Place an order, book a service, unlock access or complete an operation.
-
Backend and data
Business logic, database, APIs and error handling.
-
Product management
An admin panel for the content, users and operations your first release needs.
-
Analytics and testing
Key journey events, testing and launch preparation.
03 / DEVELOPMENT COST
An estimate built
around your product.
Telegram Mini App development cost depends on user journeys, integrations and data requirements. We separate the essential first release from later stages.
A focused MVP
Catalogue, booking or account
Screen count, design readiness and whether you already have an API shape the estimate.
A payment-enabled product
Commerce, subscriptions, integrations
Payment flows, refunds, CRM, staff permissions and administration add to the scope.
Fintech / Web3
A wallet or asset-based product
Custody, external APIs, user verification, security and load requirements need separate assessment.
04 / REAL PROJECT · 2024
MetaSwap.
Beyond a bot.
A custodial cryptocurrency wallet with a Telegram Web App interface. An example of how we connect a customer-facing product, external APIs and an administration system.
Read the case study (RU)The task
Build a wallet for managing assets, transfers and exchange, with Telegram authentication and custodial storage.
What we built
- Balances, assets, deposits, transfers and swaps.
- Automatic conversion, transaction history and an address book.
- Two-factor authentication, verification and account recovery.
- An admin panel for users, transactions and fees.
The development delivered a Telegram Web App with a backend, integrations and an admin panel. The case study shows the interface and completed scope in detail.
This case documents work completed in 2024. New products are designed around the current Telegram platform requirements.
05 / INTEGRATIONS
Connected to
your business
Telegram and your bot
App launch, authentication, deep links and notifications with the required user permissions.
Payments
Stars for digital goods and services inside Telegram. A suitable payment provider for physical goods and services.
CRM and existing systems
Sync orders, customers and statuses with your CRM, ERP or internal API.
TON and wallets
Wallet connections through TON Connect and TON functionality chosen for your use case.
Analytics
Track entry, progress and target actions to understand where users leave the journey.
Administration
Manage content, roles, permissions and operation logs without a developer for every routine task.
Decisions to make before development
Payment rules
Stars are required for digital goods and services inside Telegram. Cryptocurrency cannot replace them for those purchases.
Platform behaviour
Validate incoming data on the server. Adapt the interface to themes, screen sizes and client versions.
Blockchain functionality
New blockchain integrations must account for Telegram’s TON, TON Connect and asset-management requirements.
Development stack
We choose technologies around your product needs and existing infrastructure.
Interface
React · Vue.js · TypeScript
React or Vue.js powers a responsive interface. TypeScript adds type checking and helps the application evolve.
Backend
Business logic, APIs and data handling connect the app to payments, your CRM and internal systems.
Telegram connection
Mini Apps SDK · Bot API
The SDK connects the interface to Telegram themes and controls; the Bot API handles the bot and notifications. Authentication data is validated on the server.

Blockchains we work with

Review excerpt
Before you start
development
How much does Telegram Mini App development cost?
We estimate the actual scope: user journeys, design, backend, payments, administration and integrations. Infrastructure and third-party services are considered separately. Share your idea or specification so we can define the first release.
How long does development take?
Timing depends on requirements and design readiness, integration count and business logic. We create a delivery plan after scoping the MVP. New features are estimated separately so their impact on timing is clear.
Do I need a technical specification?
No. Start with the problem, audience and examples. We can help define the core journey and requirements for an MVP.
How is a Mini App different from a Telegram bot?
A bot handles conversations, commands and notifications. A Mini App adds a web interface for catalogues, forms, accounts and more complex journeys. The two usually work together.
Can you add payments and subscriptions?
Yes. Digital goods and services inside Telegram use Stars. For physical goods and services, we select an available payment provider. Payment, refund and status flows are included in the requirements.
Can you reuse our website or backend?
Often, existing APIs, business logic and parts of the interface can be reused. We first review authentication, Telegram adaptation and code quality, then estimate the changes.
Can the app integrate with TON?
Yes. We scope TON functionality and TON Connect integration around current Telegram rules. Products handling assets also need decisions about custody, permissions and user verification.
What happens after launch?
We agree on access, documentation and a support arrangement. Feedback, analytics and product goals guide the next steps: fixes, new journeys and further integrations.
