Description
Juggler is a desktop workbench for AI coding agents. Tool calls, approvals, thread structure and raw context are laid out in Finder-style columns. Conversations branch into sub-threads. Every tool is a JavaScript plugin. Free, open-source, one Go binary.

Could you build this?
Partial While the Miller columns desktop UI can be built with Electron or Tauri, creating an extensible, persistent tree-based agent execution harness with client/server synchronization and robust sandboxed plugin execution requires intricate systems architecture.
What it would actually take: The architecture involves a Go backend managing process lifecycles, WebSocket synchronization across clients, session persistence via SQLite or a bespoke DAG store, and a sandboxed JavaScript runtime (like goja or v8) for tool execution. The hard part is managing non-linear branching LLM conversation state, process approvals, streaming token diffs, and context window pruning without state desynchronization.
