49Agents · Coding · Productivity
49agents IDE is a multi-agent workspace for running and managing AI coding agents across your projects and machines. Think of it as a self-hosted agent IDE. Instead of juggling a stack of terminal tabs, you place every terminal, repo, and agent pane on one infinite, zoomable plane. It works with Claude Code and similar command-line agents. Run AI agents on your own hardware or a cloud box, and it stays free for individuals under the BSL 1.1 license.
About 49agents IDE
What Is 49agents IDE
49agents IDE is a development environment built around a single infinite canvas rather than a tab bar. Each agent you run, whether that's Claude Code, Codex, or a plain shell, gets its own pane on that plane, which keeps every session visible at once. Panes glow blue while an agent is working and pulse vermillion the moment it needs your permission, so you can see the state of a whole fleet of agents at a glance. The feature set targets the specific fatigue of managing many long-running agent sessions at once.
The tool works as an AI coding agent manager, leaning on the machines you already own. You connect your laptop, your desktop, and a cloud server, and then open terminals on any of them directly from the canvas, each with a live CPU and RAM readout. It's aimed at developers who treat AI coding agents as a core part of their workflow and want one place to watch them all. That's the whole pitch. One screen, every agent.
The biggest limitation isn't a missing feature, it's the setup. You self-host by cloning a repo and running two commands, and that requires Node 18 or later, tmux, and ttyd already installed. No login, no token, but also no hand-holding. There's a hosted app if you'd rather skip the install, and multi-user coworking isn't part of the free tier.
So who is this for? Mostly developers already comfortable in a terminal.
Getting Started
- Make sure the machine has Node 18+, tmux, and ttyd installed.
- Clone the repo:
git clone https://github.com/49Agents/49Agents.git, thencd 49Agents. - Run
./49ctl setupto install dependencies and configure the app. - Run
./49ctl start, then open http://localhost:1071 in your browser. No account or token is needed. - Add your other machines from the canvas and open agent terminals on them directly.

Tasks
- Watching long-running agent jobs
- Juggling several repos in parallel
- Monitoring resource use across machines
Scenarios
- Overnight agent runs where you want to check in fast in the morning
- Working from a laptop while a heavier job runs on a remote server
- Onboarding a teammate into your agent workflow
Key features
Infinite agent canvas
Every terminal, repo, and agent you run sits on one infinite, zoomable plane. You pan and zoom instead of hunting through a tab stack, which cuts the mental overhead of tracking what is running where. For anyone juggling more than a couple of agents, this is the core reason to use the tool.
Live agent status
Panes glow blue while an agent such as Claude is working and pulse vermillion the moment it needs your permission. That visual cue means you don't have to poll each terminal to find the one that's waiting on you. Big time-saver. It matters most when several agents run at once.
Multi-machine terminals
You connect the machines you own and open terminals on them directly from the canvas. Laptop, desktop, cloud server. All reachable from one screen, with no separate SSH windows to manage. It effectively turns a handful of boxes into a single workspace view.
Per-machine resource HUD
Each connected machine shows a live CPU and RAM readout on the canvas. When a build or an agent run feels slow, you can see whether the host is actually the bottleneck before you start guessing. No more blind waiting.
Local self-hosting
The app runs on your own hardware through a short setup: clone the repo, then ./49ctl setup and ./49ctl start. It opens on localhost with no account, login, or token. Nothing leaves your machines unless you choose the hosted version.
Hosted option
If you'd rather not self-host, 49agents offers a hosted app at app.49agents.com. Same canvas, no install. That suits developers who want to try it before committing to the local setup.
Coworking and shared canvases
The company tier adds shared canvases and a coworking mode, so multiple people can work on the same plane. Small teams can pool their agents and machines in one view. No separate setups required.
Pros and cons
Pros
- Free for individuals and small teams under the BSL 1.1 license.
- Self-hosting needs no account, login, or token, which keeps your code and agents on your own machines.
- The canvas plus the blue/vermillion status cues make many concurrent agents far easier to track than a tab stack.
- Multi-machine support with per-host CPU and RAM readouts covers home labs and cloud boxes alike.
Cons
- Self-hosting requires Node 18 or later, tmux, and ttyd to already be installed, so it isn't a one-click install for beginners.
- No public API, which means you can't wire the tool into other systems or scripts right now.
- Shared canvases and coworking mode are locked behind the paid company tier, so free users work solo.
