Hello Linux Geeksters. As you may know, Telegram is a an instant messaging service similar to WhatsApp. While there isn’t any official Telegram client for Linux systems, the users can use Telegram via the Unity Webapps Telegram Application (on Ubuntu 14.04 and Ubuntu 13.10 only) or via Sigram, a Telegram client developed in Qt.
Also worth mentioning, the Telegram developers are working at a special Telegram Client for Ubuntu Touch, which will have GUI matching Unity 8.
For GSoC (Google Summer of Code) 2014, Alexandr Akulich, a third-party developer is working at Telegram Connection Manager, an open-source plugin that brings Telegram support to Telepathy, a multi-protocol instant messaging software similar to Pidgin, but used by default on KDE. Also, being DE-independent Telegram Connection Manager should work for Jolla, Empathy and other multi-protocol IM clients.
Telegram Connection Manager is still in early development, so we can’t know when it will be usable, but I will keep you posted if anything new comes out. For more information, follow the developer’s blog.
