The AI coding agent built for the terminal.
AI Development Tool
Summary
Juggler is an open-source GUI workbench for AI coding agents that displays tool calls, branching threads, and raw context in a Miller column layout. It runs as a single Go binary locally or remotely, with all LLM-facing tools and context items as JavaScript plugins.
Highlights
- Miller column layout presents tool calls, approvals, thread structure, and raw context as an inspectable document rather than a terminal log
- Sessions are recursive trees with branching sub-threads supporting navigate, drill down, backtrack, duplicate, delete, and undo/redo
- All LLM-facing tools, context items, loop strategies, and slash commands are JavaScript plugins that can be inspected, forked, or replaced
- Supports simultaneous local and remote client views (desktop app and browser) all synced to the same session state
- Supports Claude Code, OpenAI, Gemini, Ollama, OpenRouter, and Deepseek as LLM providers
