Juggler - Open-source GUI coding agent with editable conversation trees

Show HN: Juggler – an open-source GUI coding agent, by the creator of JUCE

Juggler is an open-source GUI coding agent designed for developers who demand hands-on control over their LLM interactions. Unlike traditional chat-based agents, it offers a visual workbench where conversations are structured as editable trees rather than linear transcripts. Built by the creator of JUCE, it features a native desktop app with multi-client architecture, allowing seamless collaboration across browsers and devices. Users can inspect tool calls, manage branching threads, and extend functionality via JavaScript plugins, all while supporting major models like Claude, OpenAI, and Ollama.

"It is a proper GUI. This is not a console app. It's all about graphical visual navigation, inspection, and control."
