Running your community on Telegram or Discord with no control over who joins, no way to verify members, and no monetisation layer of your own?
Growing an audience on a platform that can ban your channel, change its algorithm, or shut down your community with no appeal?
How to Build an App Like Telegram
Telegram became the default platform for crypto communities, independent media, creator audiences, and professional groups that wanted more than WhatsApp could offer. Groups up to 200,000 members, broadcast channels with unlimited subscribers, a bot API that developers worldwide have built on -- these features make Telegram a community operating system, not just a chat app.
This guide is for founders who want to build a community platform, a creator tool, or a niche network where they own the data, the monetisation, and the relationship with members -- not developers.
Channels and broadcast publishing to unlimited subscribers with engagement analytics
Large group chats with moderation tools, admin hierarchy, and member verification
Bot framework for automated workflows, member onboarding, and content delivery
File sharing up to large sizes with organised media libraries and search
Building a community or messaging platform like Telegram costs $70,000--$160,000 depending on features. Core modules include channels, large group chats, a bot framework, file sharing up to large sizes, and member management. A minimum viable platform ships in 14--20 weeks. RaftLabs builds community platforms at fixed cost.

Why owning your community platform matters
Telegram has 900 million monthly active users. Communities that built their audience on Telegram did so on infrastructure they do not own. Platform rule changes, account bans, and policy shifts have wiped out communities built over years.
The business case for owning your community platform is straightforward. You control the membership terms. You control the monetisation -- subscriptions, paid tiers, premium content, sponsored posts, direct sales. You control the data, which means you know who your members are and can communicate with them outside the platform. You control moderation without depending on a policy team in another country.
For crypto projects, creator businesses, professional associations, investment research networks, and media brands, a private community platform is a direct business asset. Telegram is a distribution channel. Your own platform is infrastructure.
What makes Telegram work
Telegram's technical advantage is speed and reliability at scale. Its MTProto protocol handles large file transfers efficiently and maintains connections on poor mobile networks. Groups scale to 200,000 members without the performance degradation that affects other platforms.
The bot API is Telegram's moat for communities. Bots handle member verification, content scheduling, quiz delivery, access control, payment collection, and automated moderation. The community owner defines the workflow; the bot executes it automatically.
Channels separate broadcasting from conversation. A channel creator publishes to all subscribers without receiving replies in the channel feed. Discussion groups linked to channels give subscribers a place to respond. This separation -- broadcast and discussion as distinct spaces -- is what makes large community management tractable.
Core features you need to build
Broadcast channels
One-to-many publishing where the channel owner posts to all subscribers and subscribers cannot reply directly in the channel feed. Subscribers receive posts as they would receive a newsletter, but in real time on their phone.
Post formats support text, images, video, audio clips, polls, and file attachments. Scheduled posting lets content teams prepare a week of posts in advance and publish them at configured times. Channel analytics show subscriber growth, post reach, and engagement rate per post.
Linked discussion groups attach a community chat space to a channel. Subscribers who want to discuss a post join the linked group. This separates the broadcast experience from the conversation without losing the connection between the two.
Large group chats
Group chats that support thousands of concurrent members with real-time message delivery and no visible performance degradation. Admin hierarchy with multiple admin levels and configurable permissions per level -- some admins can ban members, others can only pin messages.
Moderation tools include slow mode (rate-limiting how often any member can post), keyword filters that automatically remove or flag messages, a join request approval queue for private groups, and the ability to restrict media sharing to admins only.
Member verification workflows connect to external services or custom logic. A crypto project can require wallet ownership verification before a member gains access to a premium group. A professional network can require LinkedIn profile confirmation.
Bot framework for automation
A bot runtime that executes automated workflows inside your platform without requiring members to leave the app. Bots send scheduled messages, collect form responses, issue access tokens, process payments, deliver files, and route questions to human agents.
The onboarding bot is the most commonly used pattern: a new member joins, the bot sends a welcome message, asks qualification questions, assigns the member to the right sub-group based on their answers, and sends a welcome pack with key resources.
Bots can be triggered by member actions (joining a group, posting a keyword, clicking a button), by schedule (daily digest at 9am, weekly summary on Friday), or by external webhooks from your other systems. This is the workflow automation layer that turns a chat platform into a product.
File and media sharing
File sharing that supports large attachments -- documents, presentations, video files, ZIP archives, and raw data exports -- without forcing users to external storage links. Files shared in a group are indexed and searchable. Members can find a document shared three months ago without scrolling through thousands of messages.
Media libraries organise shared images and videos by channel or group. Admins can pin key resources to a dedicated Files tab that members access directly.
Storage quotas by member tier enable monetisation -- free members get basic storage, paid members get expanded limits. This is the file infrastructure that makes a community platform a working resource hub rather than just a chat room.
Member management and access tiers
A member directory with profile data, join date, activity metrics, and group membership history. Admins search, filter, and bulk-action members from a web dashboard without touching the mobile app.
Access tiers map to monetisation. Free members access public channels. Paid members unlock premium groups, private channels, or direct bot interactions. Lifetime members get permanent access. Admins configure which content is available at which tier without writing code.
Join links with configurable expiry, single-use codes for controlled invitations, and public join pages for open communities. Invite tracking shows which referral source produced each new member.
Monetisation and payments
Native payment collection for paid community tiers, premium content, and sponsored access. Members subscribe to paid tiers, purchase one-time access passes, or pay for specific content bundles inside the platform without leaving for an external checkout.
Subscription management handles recurring billing, dunning for failed payments, and automatic tier downgrade when a subscription lapses. Creators receive payouts on a configurable schedule minus platform commission.
Digital product delivery -- PDFs, video courses, data exports, research reports -- triggered automatically by a completed payment. The monetisation layer that converts audience into revenue without requiring a separate e-commerce platform.
Business model options
A community platform like Telegram can generate revenue in several ways. Member subscriptions charging monthly or annual fees for access to premium tiers is the most predictable model. Platform commission on creator monetisation -- taking a percentage of every paid subscription or digital product sale that happens on your platform -- scales with your community's economic activity.
Sponsored content tools let brands pay to reach verified segments of your member base. Unlike external ad networks, you control which sponsors appear and what they can promote, which protects community trust.
API licensing lets developers build bots and integrations on top of your platform for a monthly fee. White-label deals sell the platform to other community operators who want your infrastructure under their own brand.
What RaftLabs builds for you
Platform architecture and scoping
Before writing a line of code, we document every workflow in your community platform and define exactly what gets built at what cost. We design the architecture to handle your projected member count at launch and at 10x growth without requiring a rebuild.
You get a fixed scope document and fixed price before signing any development contract.
Web and mobile apps
Browser-based web app and native iOS and Android mobile apps. Members access your community from any device with a consistent experience. The admin dashboard runs in any browser and gives you full control without requiring technical knowledge.
We use React Native for mobile so a single codebase covers both iOS and Android, reducing ongoing maintenance cost.
Bot framework and automation
A bot runtime built into your platform with a visual workflow editor for non-technical admins. Pre-built bot templates for member onboarding, access control, scheduled broadcasts, and payment-gated content.
Custom bot logic for your specific workflows. API webhooks connect your bots to external tools -- your CRM, your email platform, your payment processor.
Payments and subscriptions
Stripe integration for subscription billing, one-time purchases, and creator payouts. Configurable commission splits. Subscription management with automated dunning and tier changes.
Digital product delivery triggered by payment events. Tax handling for international customers if required.
Launch and ongoing support
Production deployment on your preferred cloud infrastructure. Load testing to confirm performance at your expected launch volume. Staff and admin training with documentation.
Post-launch bug fixes included. Monthly maintenance retainer available for feature additions after go-live.
Frequently asked questions
A core community platform with channels, large group chats, file sharing, member management, and mobile apps typically costs $70,000--$110,000. Adding a bot framework, payments, subscription tiers, and creator monetisation typically brings the total to $100,000--$160,000.
Cost depends on the number of concurrent members you need to support at launch, the complexity of the bot automation layer, payment integration requirements, and whether you need white-label or multi-tenant architecture. We scope every project before pricing.
A minimum viable community platform with channels, group chats, file sharing, and member management ships in 14--18 weeks. A full platform with bots, payments, subscription tiers, and admin analytics takes 18--26 weeks.
We deliver in phases. You can launch with core features and onboard your first members while we build the advanced layers.
We build migration tools that import member lists, message history, and shared files from Telegram where the API allows. Complete message history migration is subject to Telegram's export limits.
For most communities, the practical approach is a parallel launch -- announcing the new platform to your Telegram audience and running both for a transition period while members migrate at their own pace.
The architecture decisions we make during scoping determine how your platform performs at 10,000 members versus 500,000 members. We build on proven real-time infrastructure -- Redis for connection state, PostgreSQL or similar for persistence, object storage for media -- with horizontal scaling built into the design from the start.
We have built platforms that handle 300+ simultaneous real-time users and document the capacity planning decisions so your team understands the upgrade path as you grow.
Both options are supported. You configure the membership model -- open (join with any username), email-verified, or fully KYC'd with identity document verification. Different groups or tiers within the same platform can have different identity requirements.
For financial communities or regulated use cases, we integrate identity verification services that confirm member identity before granting access to specific content or groups.
