Juggler is a visual workbench for AI coding agents that replaces linear chat transcripts with an editable, branching tree structure.
Built by the creator of JUCE, it uses a Miller-column interface to allow developers to inspect tool calls, manage sub-threads, and persist session states across restarts.
- 01
Branching session trees using Yjs CRDTs
- 02

- 03
Persistent sessions that survive app restarts
- 04
JavaScript-based extension SDK for custom tools and UI
- 05
Multi-client support (native desktop app and browser sync)
Free
The core software is free and open-source (AGPLv3). While the open-source version supports local and LAN access, official binaries from juggler.studio include additional WAN access modes that may be subject to separate commercial licensing.
Best for
Senior developers and software architects who require granular control over AI tool calls and prefer visual, tree-based project management over linear terminal transcripts.
Not ideal for
Beginners needing simple chat-based assistance, users requiring built-in sandboxing or worktree isolation, and those on locked-down enterprise hardware.
Juggler is a highly promising, architecturally distinct alternative to terminal-based agents, offering a superior visual interface for complex coding tasks, though it currently lacks some mature features like sandboxing.
The project is in active development with frequent releases; recent focus has been on stability, UX refinements, and expanding the plugin-based architecture for tools and strategies.
