## What it is
Teamgram Server is an unofficial open-source MTProto 2.0 server implementation written in Go that is compatible with official Telegram clients. It enables self-hosted Telegram-style messaging with private chats, basic groups, and contacts, backed by MySQL, Redis, etcd, Kafka, and MinIO.

## Use cases
- self-host a telegram-compatible messenger server
- run a private MTProto server in golang
- deploy my own chat server that works with telegram clients
- host an internal messaging platform for my company
- replace telegram server with an open source implementation
- set up a self-hosted IM server with docker

## When to choose
- you want full control over your messaging infrastructure while keeping Telegram client compatibility
- you need a self-hosted messenger for privacy or compliance reasons
- you are building on or studying the MTProto protocol in Go

## When to avoid
- you need full Telegram feature parity such as channels, secret chats, or bots
- you want a simple chat server without heavy dependencies like Kafka, etcd, and MinIO
- you require a production-proven, officially supported Telegram server
