Infinite Canvas for Claude Code: How to Use the Open-Source 49Agents IDE

What It Does — A Visual, Multi-Device Workspace

49Agents is an open-source, agentic IDE that introduces an infinite canvas workspace. Unlike traditional IDEs or terminal tabs, it places every component—terminals, git interfaces, notes, and system monitors—into movable, resizable panes on a single, zoomable surface. The key feature for Claude Code users is its ability to connect multiple devices to one shared canvas without SSH, allowing you to see and control your development environment from any browser.

For developers using Claude Code, this means you can run your claude code session in a terminal pane and have it visually co-located with your git operations, a notes pane for your CLAUDE.md, and real-time monitors for CPU, RAM, and—critically—Claude API usage across all connected machines.

Setup — Connecting Your Claude Code Session

Getting started is straightforward, as no local setup is required.

1. Sign Up & Create a Canvas: Go to 49agents.com, sign up, and start a new project. This creates your infinite canvas.
2. Add a Terminal Pane: On your canvas, add a new pane and select the Terminal type.
3. Connect Your Machine: The terminal pane will provide a connection command. Run this command in your local terminal to link your machine to the canvas.
4. Run Claude Code: Within the newly connected terminal pane on the canvas, you can now run claude code as you normally would. Your session is now visible and controllable from the browser.

You can repeat this process from a second machine (like a laptop or cloud instance) to add its terminal to the same canvas, creating a unified view.

When To Use It — Specific Workflows for Claude Code

This tool shines in specific collaborative and oversight scenarios that augment Claude Code's CLI nature.

• Multi-Service Development & Debugging: When using Claude Code to work on a microservices architecture, you can dedicate terminal panes to claude code sessions for different services, alongside panes showing their logs and resource usage, all on one screen.
• Pair Programming & Review: Share your canvas URL with a colleague. They can see your live Claude Code terminal, watch as you implement features with AI assistance, and use a notes pane to provide feedback or edit the CLAUDE.md spec in real-time—all without sharing your screen via Zoom.
• Long-Running Task Supervision: Use Claude Code's new scheduling feature for a recurring task. Instead of checking a disconnected terminal, you can leave the canvas open in a browser tab. You’ll see the task's terminal pane alongside a resource monitor, giving you a passive, ambient view of its status and cost (via the Claude usage monitor).
• Context Preservation for Complex Tasks: For a deep refactoring or research task (like the genealogy projects mentioned), use a notes pane to keep the core project prompt and CLAUDE.md principles always visible next to the active Claude Code terminal, reducing context-switching and keeping the agent on track.

While not a replacement for your primary editor, 49Agents acts as a powerful visual orchestration layer for the agentic workflows you already manage with Claude Code in the terminal.
