Humbug: GUI-based agentic dev platform built with only 3 dependencies

Humbug is a GUI-based agentic development platform built with only three dependencies, designed for developers who want to rapidly prototype and orchestrate AI agents through a visual interface without heavy framework overhead. It is interesting because it challenges the trend of bloated tooling by proving that a functional, interactive agent platform can be created with minimal external code, making it lightweight, easy to understand, and ideal for experimentation or education.
