Download HexChat – IRC client for Windows, macOS & Linux

Overview

HexChat is a free, open‑source Internet Relay Chat (IRC) client that brings the classic XChat experience to modern operating systems. Built on the same codebase as XChat, HexChat retains the familiar multi‑channel interface while removing the licensing fees that once restricted casual users. Whether you’re a veteran of early‑day chat rooms or a developer looking for a lightweight, scriptable IRC client, HexChat offers a secure, customizable environment that runs on Windows, macOS, and most Unix‑like systems. The program supports multiple simultaneous server connections, a powerful plug‑in system, and a range of UI themes that let you tailor the look and feel to your taste. Because it is released under the GPL, you can inspect, modify, and redistribute the source code without any legal hurdles, making it an ideal choice for tech‑savvy communities that value transparency and control. In an age where proprietary messaging platforms dominate, HexChat stands out as a community‑driven alternative that stays true to the core principles of IRC: openness, simplicity, and real‑time communication.

macOS

1. Download the macOS .dmg package from the HexChat download page.

Once connected, you can use familiar IRC commands: /msg nick message for private messages, /nick newname to change your nickname, and /list to browse available channels on the server. The settings dialog (accessible via Settings > Preferences) lets you tweak fonts, colors, and notification behavior to suit your workflow.
