We were approached by a team to develop a scalable Telegram Mini App application in the “clicker” genre with a deep referral system and tournaments. The main task was to ensure fault tolerance under high loads and build product mechanics in such a way as to attract users without a direct advertising budget (UA).
We completely designed the UI/UX interfaces, developed a server architecture on a high-load stack and integrated Telegram Stars and crypto wallets. Below we analyze in detail what the cost of such a project consists of and how to avoid unnecessary expenses.
1. What affects the cost of developing a TMA?
Unlike traditional mobile applications for iOS and Android, the development of Telegram Mini App is based on standard web technologies (React, Vue, Node.js, Go), but has a number of key features. The main advantage is that there is no need to undergo lengthy moderation in the App Store and Google Play.
The main factors shaping the final price tag are:
- Complexity of UI/UX design: Custom 3D graphics, complex web animations (Lottie, PixiJS, Three.js) or use of ready-made Telegram UI Kit components.
- Integration with backend: Necessity of connection with CRM systems, internal databases, external payment gateways, smart contracts (TON/EVM) and Telegram Stars.
- Load requirements: Planned DAU (Daily Active Users), resilience under peak viral traffic, and the frequency of client-server data synchronization.
2. Stages and labor estimation
Any commercial project goes through four main stages. Below is the average breakdown of hours and processes for an average busy service.
Important: A common Mini App budgeting mistake is underestimating server capacity during viral growth loops. If the app starts trending, the infrastructure must handle hundreds of thousands of requests per minute.
Stage 1. Design and UI/UX design (40-80 hours)
Development starts with a clickable prototype in Figma, allowing you to test custom scenarios early without coding costs. At this stage, a UX map, UI kit, state animations and adaptations for mobile and desktop versions of Telegram are formed.
Stage 2. Frontend development (80-160 hours)
TMA frontend is a Web SPA running inside the Telegram WebApp SDK. Here screens are laid out, interaction with native Telegram elements (MainButton, BackButton, HapticFeedback) is configured and web 3 wallets (TON Connect) or Telegram Stars are connected.
Stage 3. Backend and Infrastructure (100-220 hours)
The most critical part of a viral app. The backend handles user logic, balance accounting, referral trees, and anti-cheat protection:
- Data authorization and validation.
- Configuring Redis to cache quick actions.
- Building message brokers for the transaction queue.
Stage 4. QA, antifraud and launch (30-60 hours)
Performance testing under simulated load, API security testing, database stress tests and initial optimization before marketing launch.
3. Summary of budgets
Depending on the business objectives, the range of costs and timing is distributed as follows:
| Application Type | Key functionality | Timing | Medium Budget |
|---|---|---|---|
| MVP / Simple Service | Entry form, product catalog, basic referral, Telegram UI Kit. | 2-3 weeks | $3,000 - $5,000 |
| Gaming / Medium difficulty product | Custom 2D design, complex referral networks, leaderboards, Telegram Stars. | 4-6 weeks | $7,000 - $12,000 |
| Highload Web3 / Complex Ecosystem | Custom graphics/3D, TON/EVM smart contracts, anti-fraud, microservice architecture. | 7-12 weeks | $15,000+ |
4. How to optimize your startup budget?
- Use native components: If the task is to quickly test a hypothesis, using Telegram UI can reduce design costs by up to 40%.
- Launch MVP with phased load testing: Don't immediately build a distributed cluster of thousands of servers, but build a microservice architecture to scale the backend as your audience grows.
- Protect the API from day one: The cost of basic antifraud at the start will cost several times less than clearing the database of millions of fake referrals before bonuses are awarded.
