## What it is
An open-source C++ server that implements the Telegram Bot API as an HTTP service, built on TDLib. It can be self-hosted to run bots against a local Bot API endpoint with fewer restrictions than the cloud api.telegram.org.

## Use cases
- self-host the Telegram Bot API server for my bot
- download and upload large files through a local Bot API server
- use a local webhook with HTTP and custom ports
- serve file_path as a local path without downloading files
- run Telegram bots with higher file size limits
- move a bot from cloud Bot API to a local server

## When to choose
- your bot needs file uploads up to 2000 MB or unlimited downloads
- you want local file paths and local webhook support
- you need to self-host the Bot API for performance or data control

## When to avoid
- your bot works fine with the hosted api.telegram.org endpoint
- you cannot obtain your own api_id and api_hash
- you need HTTPS directly without a TLS termination proxy

## Facets
- artifact type: service
- maturity: active
- function: http-server, api-framework, chatbot, webhook
- domain: messaging-platforms, chatbots, apis, self-hosted, developer-tools
