Telegram Mini App development

We build a connected product inside Telegram: Mini App, bot, backend and admin tools. The starting point is the user journey and the team's operations, so entry points, notifications and data work together.

From the problem to launch

01
Design the Telegram journey
Establish where users arrive, which steps belong in the bot or the app, and where the team needs manual controls.
02
Build a connected system
Agree contracts between the Mini App, bot and backend. Progress and access decisions are enforced on the server.
03
Prepare for traffic
Test actual Telegram clients, slow connections, reopening and dependency failures. Define the expected workload and load-test scenarios.

What determines cost and timing

Number and complexity of user mechanics, notifications and admin operations.
Payments, external services and whether a wallet journey is required.
Expected workload, real-time events and abuse-prevention requirements.

/ questions

What to know before starting

Does a Mini App need a blockchain or token?

No. It can be a conventional web product with a bot and backend. TON Connect or another Web3 integration belongs in the scope only when it serves a specific user requirement.

When is a bot alone insufficient?

Bots work well for messages and simple commands. A Mini App helps when users need tables, interactive screens, a profile or complex selection. In many products the two complement each other.

Can you guarantee a particular concurrent user count?

Capacity depends on workloads, request frequency, data size and infrastructure. GrandCombat experience helps us ask the right questions, but that project's results do not automatically guarantee capacity for a different product.
