## What it is
The official open-source Telegram Desktop messenger client, built on the Telegram API and MTProto secure protocol. It is a full-featured cross-platform chat application written in C++ with Qt, available for Windows, macOS, and Linux.

## Use cases
- use telegram on my desktop
- open source messaging app for windows mac and linux
- chat app with encrypted messaging on desktop
- sync telegram messages between phone and pc
- send files and make calls from desktop
- privacy-focused messenger client
- telegram client for linux snap or flatpak

## When to choose
- you want the official Telegram experience on a desktop with full sync to mobile
- you need a native, actively maintained client for Windows, macOS, or Linux
- you want to inspect or build the client from source under GPLv3
- you need voice/video calls, file sharing, groups, and channels on desktop

## When to avoid
- you need a library or API to build your own Telegram bot or integration - use a Telegram API/MTProto library instead
- you need end-to-end encryption by default for all chats (only secret chats offer E2EE, and secret chats are mobile-only)
- you require a web-based client without installation - Telegram Web may fit better
- you need support for very old operating systems like Windows XP or macOS 10.12
