Telegram
Cloud-based messaging app
Telegram — Official Website
Quick Take: Telegram
Telegram is the most feature-rich messaging platform available. The native Mac app is fast, the cloud sync is instant, and the combination of channels, groups, bots, and file sharing creates a communication ecosystem that no competitor matches. The tradeoff is privacy: regular chats aren't E2E encrypted, and Telegram can access your messages if compelled. If you accept this tradeoff, Telegram is the best messaging experience on macOS. If you don't, use Signal for private conversations and Telegram for everything else.
Best For
- •Developers who follow open-source channels and participate in tech communities
- •Content creators who need a channel + community platform
- •Teams that want free, unlimited messaging with full history and file sharing
- •Power users who want the richest messaging feature set available
What is Telegram?
Telegram is a messaging platform that treats messaging as a feature, not the product. The product is a cloud-based communication system that includes personal messaging, group chats up to 200,000 members, public channels with unlimited subscribers, a full bot API, file sharing up to 2GB, voice and video calls, and a built-in app platform (Mini Apps) that lets developers build entire applications inside Telegram. It's used by over 1 billion monthly active users worldwide. For Mac users, Telegram offers the best desktop messaging experience of any chat platform. The macOS client is a native Swift app that's genuinely fast—it starts in under a second, scrolls through years of chat history without lag, and handles media-heavy chats without the memory bloat you get from Electron-based competitors. Messages sync instantly across all your devices because everything is stored on Telegram's cloud servers. There's no 'link your phone' ritual—sign in on your Mac, your iPad, your web browser, your work computer, and every message is everywhere immediately. The privacy picture is complicated. Telegram's regular chats are not end-to-end encrypted—they're encrypted in transit and at rest on Telegram's servers, but Telegram can technically read them. Only 'Secret Chats' (which are one-on-one only and don't work on desktop) use E2E encryption. Telegram's founder Pavel Durov has argued that cloud-based messaging with server-side encryption is secure enough for most users and that E2E encryption prevents useful features like cloud sync and multi-device access. You can agree or disagree with this philosophy, but you should understand it: Telegram prioritizes features and convenience over maximum privacy. If you want E2E encryption by default, use Signal. If you want the richest messaging platform available, Telegram is it.
Install with Homebrew
brew install --cask telegramDeep Dive: Telegram's Identity as a Platform, Not Just a Messenger
Most people think of Telegram as 'WhatsApp but with more features.' That undersells it. Telegram is closer to a communication operating system than a messaging app.
History & Background
Telegram was founded by Pavel Durov and his brother Nikolai in 2013. Pavel had previously founded VKontakte (VK), Russia's largest social network, and left Russia after refusing government demands to hand over user data. Telegram was built with anti-censorship and anti-surveillance as core values. The platform grew rapidly in markets where government surveillance was a concern—Iran, Russia, Hong Kong—and expanded globally through its feature advantages. By March 2025, Telegram reached 1 billion monthly active users.
How It Works
Telegram's architecture is cloud-first. Messages are stored on Telegram's distributed server infrastructure, not on user devices. This enables instant multi-device sync, server-side search, and permanent message history. The infrastructure is designed for scale—200,000-member groups and channels with millions of subscribers require sophisticated message fanout and delivery systems. The MTProto protocol handles encryption (server-client for regular chats, E2E for Secret Chats) and is optimized for mobile networks with poor connectivity.
Ecosystem & Integrations
Telegram's ecosystem extends far beyond messaging. The Bot API powers millions of bots handling everything from news aggregation to payment processing. Mini Apps (WebApps) turn Telegram into an app distribution platform—developers build web applications that run inside the Telegram interface with access to user authentication, payments, and social features. Telegram Payments let bots accept credit card payments through integrated payment providers. Sticker creation and distribution has its own creator community. The combination of channels + groups + bots + Mini Apps creates a platform that competes with Slack, Discord, Substack, and even simple e-commerce tools.
Future Development
Telegram is expanding its monetization through Premium subscriptions, advertising in public channels, and the Mini Apps platform (which could introduce revenue sharing with developers). Feature-wise, Telegram continues to add AI-powered features including the AI Editor for text translation and transformation, AI summaries for channel posts, message translation, voice transcription, and real-time chat translation. The bot and Mini Apps ecosystem remains where the most development energy is focused.
Key Features
Channels
Telegram Channels are one-to-many broadcast feeds with unlimited subscribers. News organizations, content creators, software projects, and communities use channels to push updates to their audience. Subscribers can react and comment (if enabled) but can't post. Channels support text, images, video, files, polls, and quizzes. Many open-source projects use Telegram Channels as their primary announcement feed—it's faster than email newsletters and reaches users on a platform they already check daily. The Mac app displays channels in a dedicated section with full media support.
Bot Platform and API
Telegram's Bot API is one of the most powerful messaging platform APIs available. Bots can send and receive messages, handle inline queries, process payments, manage groups, create polls, send custom keyboards, and serve Mini Apps (web applications that run inside the Telegram interface). Developers build bots in any language using the HTTP-based Bot API. Bots power everything from @gif (search and send GIFs), to @wiki (Wikipedia lookups), to custom automation for team workflows. The API is free, well-documented, and has a massive developer community.
Groups up to 200,000 Members
Telegram groups can have up to 200,000 members—orders of magnitude beyond WhatsApp's 1,024 limit. Groups support admin hierarchies, granular permissions (who can post, who can add members, who can pin messages), anti-spam bots, slow mode (limiting message frequency), and topic-based threads for organized discussions. Large groups function more like forums than chat rooms. The Mac app handles large groups well—message loading is fast because history is stored on Telegram's servers, not your device.
File Sharing up to 2GB
Telegram lets you share files up to 2GB each—any file type, no restrictions. Documents, videos, APKs, ISOs, ZIPs—if it fits under 2GB, you can send it. Files are stored on Telegram's cloud permanently (unless you delete the message), so recipients can download them anytime without the sender needing to re-upload. This makes Telegram a practical file-sharing tool for teams that don't want to set up a shared drive for quick transfers.
Secret Chats (E2E Encrypted)
Secret Chats provide end-to-end encryption using Telegram's MTProto 2.0 protocol. Messages in Secret Chats are device-to-device—they don't pass through Telegram's cloud and can't be forwarded. They support self-destruct timers (from 1 second to 1 week) and screenshot notifications. The catch: Secret Chats are one-on-one only, don't sync across devices (they exist only on the device where you started them), and are not available on the desktop app. This limitation is by design—E2E encryption prevents cloud sync, and Telegram chose cloud sync as the default.
Telegram Premium
Telegram Premium ($4.99/month) adds quality-of-life features: 4GB file uploads (vs 2GB), faster download speeds, exclusive stickers and reactions, no ads in public channels, voice-to-text transcription, AI Editor for message translation and transformation, profile customization (animated avatars, extended bio), and the ability to follow up to 1,000 channels (vs 500). Premium is entirely optional—the core messaging experience is free. The paid features are mostly about convenience and cosmetics, not core functionality.
Native macOS Performance
Telegram's Mac app is written in Swift and Objective-C, not Electron. It launches in under a second, uses 100-200MB of RAM under normal use, and renders chat history, media, and animations smoothly. Search is fast—you can search across all your chats, channels, and messages by keyword, date, or sender, and results appear almost instantly because the index is maintained server-side. The app supports macOS features like Quick Look (spacebar to preview files), drag-and-drop file sharing, and native notification integration.
Mini Apps (Web Apps Inside Telegram)
Telegram Mini Apps are web applications that run inside the Telegram interface. Developers build them with standard web technologies (HTML, CSS, JavaScript) and access Telegram-specific APIs for user authentication, payments, and sharing. Mini Apps can be full-featured applications—games, e-commerce stores, booking systems, or productivity tools—accessible from a chat with a bot. This transforms Telegram from a messaging app into an app platform, particularly popular in markets where mobile web adoption is high.
Who Should Use Telegram?
1The Developer Following Open-Source Projects
You follow 15 open-source projects on Telegram channels: Homebrew releases, Swift updates, Kubernetes announcements, and niche tools you use daily. Each channel pushes updates as they happen—new versions, security advisories, breaking changes. You read them on your Mac between tasks, with the native app's fast scrolling and media loading. You also participate in three developer community groups where you ask questions, share solutions, and occasionally get scooped into heated debates about programming languages.
2The Content Creator Managing an Audience
You run a Telegram channel with 50,000 subscribers where you share industry analysis, tool recommendations, and career advice. You compose posts on your Mac (full keyboard, proper text editing), schedule them for optimal times, and monitor engagement through polls and reactions. You also run a smaller private group for paying subscribers where you answer questions and share exclusive content. Telegram's channel + group combination creates a content distribution and community system without needing a separate newsletter tool.
3The Team Using Telegram for Quick Coordination
Your small team of five uses Telegram instead of Slack because it's faster, free, and everyone already has it. You share files up to 2GB without a paid plan limit. You created a bot that posts deployment notifications from your CI/CD pipeline. The search function lets you find any message, file, or link shared in the past year. And unlike Slack's free tier, Telegram doesn't hide old messages behind a paywall—your entire history is searchable forever.
4The Privacy-Aware User Making Tradeoffs
You understand Telegram's encryption model and accept the tradeoff: cloud-based chats synced everywhere vs. E2E encryption limited to Secret Chats. For sensitive conversations, you use Signal or Secret Chats. For everything else—group discussions, channel subscriptions, file sharing, bot interactions—Telegram's feature set and performance are unmatched. You've configured two-step verification and active sessions review for account security.
How to Install Telegram on Mac
Telegram for macOS is available via Homebrew, the Mac App Store, or direct download.
Install via Homebrew
Run `brew install --cask telegram` in Terminal. This installs the native macOS app. Note: there's also `telegram-desktop` (the Qt-based cross-platform version)—you want the `telegram` cask, which is the Swift-based macOS-native version.
Sign In
Open Telegram and enter your phone number. You'll receive a verification code via SMS or through the Telegram app on another device. Enter the code and you're signed in. Unlike WhatsApp, there's no QR code linking—you sign in directly.
Enable Two-Step Verification
Go to Settings → Privacy and Security → Two-Step Verification. Set a password that's required in addition to the SMS code when signing in from a new device. This prevents account takeover via SIM swapping.
Customize Notifications
In Settings → Notifications, configure per-chat and per-channel notification preferences. Mute noisy groups, enable alerts for important channels, and set notification sounds. The Mac app supports macOS Focus mode integration.
Pro Tips
- • Install the `telegram` cask, not `telegram-desktop`. The former is the native Swift Mac app; the latter is the cross-platform Qt version that feels less native.
- • Use the keyboard shortcut Command+K to open the quick chat search—jump to any conversation by typing its name.
- • Enable 'Passcode Lock' in Settings → Privacy for an extra layer of security on shared Macs.
Configuration Tips
Use Chat Folders to Organize Conversations
In Settings → Chat Folders, create folders like 'Work', 'Communities', 'Channels', and 'Personal'. Assign chats and channels to folders. Folders appear as tabs at the top of the chat list. This is essential if you follow many channels and participate in several groups—without folders, your chat list becomes unmanageable.
Review Active Sessions Regularly
Go to Settings → Privacy and Security → Active Sessions to see every device currently logged into your Telegram account. Terminate sessions for devices you no longer use. This is important because Telegram allows simultaneous logins on unlimited devices, and a forgotten session on an old computer is a security risk.
Set Auto-Delete Timer for New Chats
In Settings → Privacy and Security → Auto-Delete Messages, set a default timer (1 month is reasonable) for all new one-on-one chats. This keeps your message history from growing indefinitely without manual cleanup.
Customize Notification Sound Per Chat
Long-press (or right-click on Mac) a chat and select 'Mute' or 'Custom Notifications'. Set different notification sounds for important contacts and mute noisy groups. You can also set exceptions so certain contacts always notify you even during Focus mode.
Alternatives to Telegram
Telegram competes with messaging apps that have different privacy and feature philosophies:
Signal
Signal is the privacy-first alternative with E2E encryption on everything by default. It has much fewer features (no channels, no bots, small group limits, 100MB file limit) but is the gold standard for private messaging. Choose Signal when privacy is the priority; choose Telegram when features and community are the priority.
WhatsApp has E2E encryption by default and a larger user base (2 billion vs over 1 billion). But it lacks channels, bots, large group support, and 2GB file sharing. WhatsApp groups cap at 1,024 members. Choose WhatsApp if your contacts are there; choose Telegram for community features and file sharing.
Discord
Discord serves communities with voice channels, screen sharing, and bot integrations. It's stronger for real-time voice communication and gaming communities. Telegram is stronger for asynchronous text-based communities, broadcasting via channels, and file sharing. Many communities maintain both.
Slack
Slack is the workplace standard with integrations, threads, and search. But Slack's free tier hides messages older than 90 days. Telegram keeps your entire history forever for free. Small teams that want free, unlimited history often use Telegram instead of Slack.
Pricing
Telegram is free for all users with no feature restrictions on messaging, calling, file sharing, channels, groups, or bots. Telegram Premium ($4.99/month) adds 4GB uploads, faster downloads, exclusive stickers, no ads in public channels, and extended limits. Premium is optional and doesn't gate core functionality. Telegram is funded by Pavel Durov's personal investment and increasingly by the Premium subscription and advertising in public channels (non-Premium users see sponsored messages in channels with 1,000+ subscribers).

- ✗Channel ads for non-Premium users in large channels
- ✗The privacy model is confusing—many users incorrectly believe all chats are E2E encrypted
- ✗Moderation in large groups can be challenging even with bot assistance
Community & Ecosystem
Telegram's community is massive and diverse. Developer communities thrive in Telegram groups covering every programming language, framework, and platform. Open-source projects use channels for announcements. The bot developer community is particularly active—Telegram's Bot API documentation is excellent, and there are frameworks in Python (python-telegram-bot), Node.js (Telegraf), Go (telebot), and dozens of other languages. Telegram Mini Apps have created a sub-ecosystem of web developers building applications within the platform. Country-specific communities are large in Russia, Iran, Brazil, India, and Southeast Asia. The platform's developer documentation is available at core.telegram.org and is some of the best API documentation in the messaging space.
