Instant messaging (IM) is a form of real-time communication between two or more individuals based on typed text. The text is conveyed via devices connected over a network such as the Internet.
There are so many different instant messaging clients available, some software supports multiple protocols, others confine themselves to supporting a single protocol only.
This chart provides our recommendations. We only feature open source software here.
To provide an insight into the quality of software that is available, we have compiled a list of 15 high quality open source Linux IM clients. Hopefully, there will be something of interest here for anyone who wants to converse with their family, friends, colleagues, and clients.
An increasing number of instant messaging clients use Electron, a framework for creating native applications with web technologies such as JavaScript, HTML, and CSS. Signal, Franz, Wire, and Rambox (as well as Discord) all deploy this framework.

While we are strong proponents of open source software, it’s only fair to also recommend no-charge closed source software provided it’s sufficiently high quality. And the applications below are certainly highly respected software with huge user bases.
Telegram’s client-side code is open-source software, whereas its server-side code is closed-source and proprietary.
While Discord is an extremely popular VoIP chat tool among the gaming community, it’s instant messaging functionality is particularly impressive. Discord uses Markdown, a simple plain text formatting system that helps you make sentences stand out. Discord also supports code blocks.
Skype revolutionized the communications world with its supreme internet telephony / instant messaging / videoconferencing functionality. There’s a lot of animosity towards Microsoft, in part because they did not embrace an open source model for Windows, but more because of their predatory tactics. But the fact that Skype is powered entirely by Microsoft-operated supernodes doesn’t mean it should be excluded from this group test.
No-Charge Instant Messaging Tools | |
---|---|
Telegram | Cloud-based instant messaging and voice over IP service |
Discord | A hugely popular all-in-one voice and text chat - not only for gamers |
Skype | Make free phone calls and communicate with good instant messaging support |
The massively popular messaging app WhatsApp surprisingly doesn’t provide a native desktop client for Linux although a web version is available.

Never trust Signal. They even post a misleading Android download link. They tell you to go to ______ and then Google Spy and Track shop opens up. Hello ??? Security? I don’t need this sly cunning crap. I am just frank and outspoken and if anyone feels insulted, then they may have a valid reason for hiding truth.
