Total.js Messenger: Chat app inspired by Slack

Messenger is an open-source web application and it's a small alternative to Slack. Total.js messenger is powerful micro application for each company with open source-code.

  • Try our Chat support built on Total.js messenger:

What are the benefits? You can extend the messenger easily by custom bots, custom behaviours or custom functionality. You can provide it on your own Linux server with minimum requirements.

New future

I have prepared a components mechanism for Total.js Messenger, so the messenger will be extended very easy by new and custom functionality without changing the core code.


It's unbelievable, but minimal requirements are:

  • 1 CPU, 60 MB RAM and 60 MB of free space on HDD
  • Linux/macOS/Windows
  • Node.js platform v6+
  • Total.js framework v2.4+

What's the cost?

For downloading Total.js messenger source-code you have to have a Premium Total.js account.
