Juggler

Yes, it's another AI coding agent. The industry definitely needed one more.

If Juggler has an angle, it's that it's for people who want to be more hands-on over what the LLM is doing to their codebase. It gives you a visual workbench: inspectable tool calls, branching threads, editable context.

And here's the TL;DR:

• It is a proper GUI. This is not a console app. It's all about graphical visual navigation, inspection, and control.
• The session is a tree, not a doom-scroll. It's a Yjs document, not a transcript. Create sub-threads, drill down, backtrack, compare, and edit.
• Everything important is visible. Tool calls, approvals, thread structure, item properties, raw context — laid out in Finder-style Miller columns instead of buried in collapsible chat.
• It's plugins all the way down. Context items, slash commands, LLM loop strategies, and their UIs are JavaScript extensions you can inspect, fork, or replace.
• It runs locally, remotely, or both at once. Use the same session with the same UI in the native desktop app, and/or browsers. Multiple clients can attach to the same session.
• It talks to the usual model zoo. Claude Code (via CLI or API), OpenAI (codex plan or API), Gemini, Ollama, OpenRouter, Z.AI, Deepseek, etc.
