KustBots  /  Telegram bot development

Telegram bots, built to run for years.

We design, build and operate custom Telegram bots, from a single support bot to fleets that sit in 81,300 groups. The engineers who write the code are the same people who keep it running.

What we build

  • Moderation and anti-spam — link removal, raid protection and per-chat rules, with an audit log.
  • Music and voice chat — streaming into voice chats with queues, seeking and failover.
  • Payments — crypto, Razorpay, UPI and cards inside the chat, never charged twice.
  • AI sales and support agents — answers from your own data, bookings and lead capture.
  • Mini Apps — full web interfaces inside Telegram, with wallet connections.
  • Referral, giveaway and community tools — the growth machinery around a bot.
  • Multi-tenant clones — one codebase running as thousands of isolated customer bots.

Bot API when it is enough, MTProto when it is not

Most bots only need the Telegram Bot API, and we use it wherever it does the job. When a product needs user sessions, voice chats or bulk history, we drop down to MTProto and handle it directly rather than through a fragile wrapper.

Built for scale from the first commit

A bot that works in ten groups can fall over in ten thousand. We design for the problems that only appear at scale: flood limits that escalate the harder you retry, backlogs of stale updates after a restart, broadcasts that must be paced, and sessions that expire silently.

Our link remover runs in 81,300 groups and moved from Python to Go in a single 10–15 second restart. The same thinking goes into every bot we build.

How an engagement works

  • You send one message on Telegram describing what you need.
  • We agree the scope in writing and send a quote, valid for 30 days.
  • We build, test against real traffic, and deploy with health checks and a watchdog.
  • We keep operating it: monitoring, updates, and a direct line to the engineer who built it.

Moderation & Filtering
01 / 12

Moderation & Filtering

Spam, massive raids, and malicious link floods handled directly inside the group before any members read them. We use per-chat policies and heuristic rules that can be updated on the fly without a redeploy. Every removal is strictly recorded in an immutable audit log.

Bot Cloning
04 / 12

Bot Cloning

One robust codebase deployed dynamically per customer with securely isolated config, encrypted tokens, and separate storage. A new feature ships to thousands of instances simultaneously, but a configuration mistake reaches none of the others.

Secure Payments

Frictionless crypto and fiat card flows integrated directly inside chat. Native invoices, rigorous webhook cryptographic verification, daily reconciliation, and battle-tested retry loops that are mathematically guaranteed to never charge a user twice.

Mini Apps & Web UI

Full-stack Telegram Mini Apps bridging the gap between rich web interfaces and chat. We build deeply integrated, native-feeling UIs directly inside the messenger with seamless crypto wallet connections and smooth, 60fps animations.

Questions

Asked and answered.

How much does a custom Telegram bot cost?

Every quote is per project, based on the scope we agree in writing. Message @kustbhai on Telegram with what you need and you will get a clear price and timeline, with nothing added afterwards.

Do you host and maintain the bot after it is built?

Yes. We build it and then we run it: hosting, monitoring, updates and fixes. Operating what we build is the core of how we work.

Can you take over or rebuild an existing bot?

Yes. We regularly migrate existing bots, keep their data and settings, and rewrite the parts that break under load.

Which languages do you build Telegram bots in?

Go for high-load services, Python for MTProto and AI work, and JavaScript or TypeScript for Mini Apps and edge services.
