49Agents delivers an open‑source, two‑dimensional IDE that unifies AI agents, terminal sessions, git repos and issue tables on a single zoomable canvas. Users can self‑host on localhost or scale across a cluster with Tailscale, while a hosted version at app.49agents.com is promised soon. The tool replaces tab‑heavy windows with a spatial workspace that persists layout across reboots.

On the canvas, each pane runs a tmux session via ttyd, giving ANSI colors and scrollback. A HUD overlay displays CPU, RAM and Claude API usage, and broadcast mode lets one keystroke type into terminals at once. Connections use WebSocket relays; no terminal I/O is stored server‑side, preserving privacy. Users reach the same layout from laptops, tablets or phones via LAN, Tailscale or a hosted relay.

49Agents ships under the BSL 1.1 license, free for individuals and small teams, and will switch to MIT on 26 February 2030. A quick‑start script clones the repo, runs an interactive setup and launches a cloud server at http://localhost:1071 without any account or token. Whether self‑hosted or later accessed via the upcoming SaaS, developers gain a single spatial view of all CLI‑based workflows.
