LimeChat for Mac is a free and open source IRC client for macOS developed using RubyCocoa, intended to provide both novices who have very little knowledge of how online chat networks work and seasoned users with tools that can make their online communication as easy, as stable and versatile as possible. Created with the effort of the single developer Satoshi Nakagawa in 2007, this app originally run on RubyCocoa programming language and was in 2010 ported to Objective-C. With great user interface and free access under GPL software license, anyone can install this small and lightweight app on their Mac and become fully in control over their IRC chat.

Visually, LimeChat for macOS has a look of a very simple application that is more focused on providing functional breakdown of server and room status, than on pleasing users with its eye-catching design. App has only single window separated into several section that cover everything you will ever need. Because of the lack of the visual style, majority of its services and functions can be activated only via keyboard shortcuts, which represents only a bonus for professional users who are more used to solve all of their problems without using mouse.

Even though this app has almost zero on-screen tools for managing current IRC chat sessions, it has a fairly comprehensive Preferences screen that housed dozens of tweaks that make your chat sessions more attuned to your needs and tastes. Configuration options cover everything between text highlighting, interface options, themes, events and several advanced tools.

Some key features of LimeChat:
  • One window for multiple servers.
  • Rich keyboard shortcuts for your comfortable operations.
  • Light speed and stable.
Note: Requires 64-bit processor.
