Show HN: IDE – 2D Canvas for Agents 49Agents has launched 49Agents, an open-source 2D agentic IDE that replaces terminal tabs with an infinite zoomable canvas, supporting multiple terminals, machines, and devices via WebSocket relay with zero SSH. The tool, available for self-hosting or cloud use at 49agents.com, includes features like broadcast input, HUD overlay for CPU/RAM/Claude API usage, and a Monaco editor, with no account or login required. The first 2D agentic IDE. Open source. All agents. All terminals. All projects. All machines. One unified space. 49agents-launch.mp4 | Before | 49 | |---|---| | 14 terminal tabs | One zoomable canvas | | SSH into each machine | All machines, zero SSH | | Alt-tab to check Claude | Claude status on every pane | | Can't work from phone | Any device, anywhere | | Terminal-only, no files | Monaco editor on the canvas | | 🤷 | Git graph | | 🤷 | Interactive issue tables | git clone https://github.com/49Agents/49Agents.git cd 49Agents ./49ctl setup interactive setup one time ./49ctl start start cloud server + agent Open http://localhost:1071 . No account, no login, no token. We recommend self-hosting — it's free, your terminals and files never leave your machine, and setup is two commands. If you just want to try it first, the cloud-hosted version needs no install: 49agents.com https://app.49agents.com Download the latest .dmg from GitHub Releases https://github.com/49Agents/49Agents/releases/latest . After downloading, macOS will block the app because it is not notarized. Run this once to allow it: xattr -cr /Applications/49Agents.app Then open 49Agents normally. It runs as a tray icon — look for it in your menu bar. Updates are delivered in-app: click the tray icon and choose Check for Updates . - Infinite canvas — no tabs, no splits. Place panes anywhere on a zoomable surface - Drag, resize, arrange — your workspace grows with your thinking, not your monitor - Zoom levels — zoom out for the big picture, zoom in to focus - Persistent layout — everything stays where you put it - Real tmux sessions via ttyd — full ANSI color, scrollback, your shell config - Broadcast input — type once, send keystrokes to multiple terminals simultaneously - Zero SSH — connect agents from any machine to one canvas - HUD overlay — live CPU, RAM, and Claude API usage across all connected machines - Any device — laptop, tablet, phone. Same workspace, same layout - Tailscale / LAN / hosted relay — works however you connect - Fully self-hosted — the entire stack runs on your hardware - No data stored server-side — terminal I/O is relayed, never persisted - Tab chords for pane switching - WASD move mode for spatial navigation - Shortcut numbers 1–9 for instant pane focus - Broadcast mode for multi-terminal input ┌──────────────┐ WSS ┌──────────────┐ WSS ┌──────────────┐ │ 🖥️ PC │ ────────►│ ☁️ Relay │ ◄──────── │ 📱 Browser │ │ 49-agent │ │ │ │ │ └──────────────┘ └──────────────┘ └──────────────┘ Self-host or use 49agents.com Multi-machine setup ┌──────────────┐ ┌──────────────┐ │ 🖥️ MacBook │ ─── WSS ───┐ ┌───│ 📱 Phone │ │ 49-agent │ │ │ │ Browser │ └──────────────┘ │ │ └──────────────┘ │ ┌──────────────┐ │ ┌──────────────┐ ├──►│ ☁️ Relay │◄───┤ ┌──────────────┐ │ 🖥️ PC │ ─── WSS ───┤ │ │ ├───│ 💻 Laptop │ │ 49-agent │ │ │ Self-host │ │ │ Browser │ └──────────────┘ │ │ or use │ │ └──────────────┘ │ │ 49agents.com │ │ ┌──────────────┐ │ └──────────────┘ │ ┌──────────────┐ │ ☁️ Azure VM │ ─── WSS ───┘ └───│ 📱 Tablet │ │ 49-agent │ │ Browser │ └──────────────┘ └──────────────┘ Each agent independently connects to the relay via WebSocket.
