The open-source workspace for coding agents.

supermux runs Claude Code, Codex, and other coding agents on your own computer or server, many sessions at once, 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.

  • 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.
Claude Code finds what billing-api needs to start and saves it to ~/.mux/domains/billing.md. A Codex session started afterwards reads the note and writes .env.example. Recorded on the demo host; long waits are shortened.

Editor, terminal, and ports on every device

The same workspace runs on desktop, tablet, and phone.

  • 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

Move a Claude Code or Codex session that hits its limit to another account and continue.

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.
