// the take
Fabulor is a GTK4 IRC client for Windows 11+, built on .NET 8, positioning itself as a modern successor to XChat/HexChat/ZoiteChat with IRCv3 support and scripting in C#, Python, and Tcl. It's aimed at power users who want a classic multi-channel IRC UI with real plugin extensibility rather than a web-based chat client.
Three first-class scripting languages (C#, Python 3.14, Tcl) each with their own plugin authoring guide and API reference, which is more scripting surface than HexChat ever shipped. IRCv3 is called out explicitly rather than bolted on as an afterthought. There's an actual CI pipeline (Windows build, tests, lint) rather than just a solo dev pushing binaries. The docs go deep on Windows-native integration specifics (DPI awareness, tray behavior, notification architecture) that most cross-platform GTK ports skip or get wrong.
One star, zero forks, first release cycle — there's no evidence yet this has been run outside the maintainer's machine, and a desktop IRC client with a plugin system executing C#/Python/Tcl has a real attack surface that needs field testing. The installer is unsigned with no active code-signing certificate, and the project has explicitly dropped pursuing SignPath, so every install trips SmartScreen indefinitely — a hard adoption tax for a Windows-only tool. Windows 10 is 'best-effort and unsupported,' which cuts out a sizable chunk of the potential user base for no stated technical reason. Security hardening is credited to AI-assisted review (OpenAI Codex) plus CodeQL/Gitleaks, which the README itself flags as not equivalent to independent certification — reasonable as a floor, not a substitute for a real audit given the plugin execution surface.
