<strong>The open-source workspace for coding agents.</strong><br>
supermux runs Claude Code, Codex, and other coding agents on your own computer or server, many sessions at once,<br>
and lets you work with them from your desktop or phone.

---
## Run many sessions at once
- **Parallel sessions:** Run as many agents as you need, each in its own git worktree.
- **Know who needs you:** Get notified when a session finishes or asks a question.
- **Review before merge:** Read the diff, comment inline to the agent, then merge, open a PR, or discard.
- **Mix agents:** Change the agent, model, reasoning level, or fast mode per session.
## Shared memory across agents
Each agent CLI keeps what it learns to itself. supermux gives them one shared memory as Markdown files on your machine.
<p align="center"><img src="assets/readme/memory.gif" alt="Claude Code saves what billing-api needs to start to ~/.mux/domains/billing.md, and a Codex session started afterwards reads it and writes .env.example"></p>
- **Write once:** Sessions save what they learn to a file per topic.
- **Read everywhere:** Every new session starts with the topic index, whichever agent runs it.
- **Same for context:** Set up instructions, skills, plugins, and MCP servers once for every agent.
## Editor, terminal, and ports on every device
The same workspace runs on desktop, tablet, and phone.
<p align="center"><img src="assets/readme/phone.png" alt="Chat, code editor, and terminal with a key bar on a phone" width="760"></p>
- **Code editor:** Edit any file with syntax highlighting, search, and language-server completion.
- **Terminal:** Open a full terminal in any workspace, with a key bar for phone keyboards.
- **Expose ports:** Turn any port on your machine into a private or public link.
- **Files both ways:** Send photos and files to a session, and get screenshots, documents, and videos back in the chat.
## Keep going when you hit a usage limit
- **Several accounts:** Sign in to work and personal accounts per agent and see all usage in one place.
- **Auto-switch:** Move a Claude Code or Codex session that hits its limit to another account and continue.
- **Your subscriptions:** No API keys and no supermux account.
## Nothing to install first
- **Agents installed for you:** Pick your agents and supermux installs their CLIs.
- **Guided sign-in:** Sign in to each agent from the desktop or your phone.
## Also included
- **Desktop and server:** Run it on macOS, Windows, Linux, or a headless server, and see every machine's sessions in one app.
- **Always on:** Sessions survive closed laptops, dropped connections, and reboots.
- **Search:** Find any message across every chat on every machine.
- **Voice:** Dictate into the composer and have replies read aloud.
## Where your code and traffic go
- **Stays local:** Repositories, credentials, and session history stay on your machine.
- **Relay when away:** Reach your machine through the supermux relay, or turn it off and use your own VPN or proxy.
- **Pairing, not accounts:** Pair devices with a single-use code. Each install belongs to one person.
- **Anonymous usage events:** Your broker sends which agents, models, apps and features you use, never prompts, code, paths or names. [See every field](./TELEMETRY.md), or turn it off with `MUX_TELEMETRY=0`.

The first launch of a desktop app sets it up and shows a QR code. Scan it with the phone app.
### Headless Linux and servers
```sh
curl -fsSL https://supermux.dev/install.sh | sh -s -- --native
```
Installs `supermux` as a user service and prints a pairing QR. Docker and source installs are in the [setup guide](./SETUP.md).

## FAQ
**Is supermux an agent?**
No. It runs the agent CLIs you already use, like Claude Code and Codex, and it is where you work with them. It is not a cloud service either.
**Is it free?**
Yes. supermux is open source under the MIT license, and it runs on the agent subscriptions you already have.
**Can my team share one install?**
Not yet. Each install belongs to one person. Each teammate runs their own.
**Does Windows need WSL?**
No. The Windows app runs agents natively.
