native ios & android

A real native app.
Not a web wrapper.

Talk to any session with text, voice notes, photos, or files. Push notifications land the moment an agent needs input or review — and it all feels like an app, because it is one.

  • Real push notifications when a decision is needed
  • Voice, photos, files — straight into the session
  • Full web app too — same sessions from any browser

always-on sessions

You leave.
It doesn't.

meanwhile, on your machine

▸ bun test — 212 passed ▸ edit src/channels/web/session.ts ▸ commit “wire session resume” ▸ opening review — waiting on you

Sessions live on your box, not in a browser tab. Walk out the door and the work keeps moving — each session in its own git worktree, on its own branch.

review & control

It asks.
You decide.

When an agent finishes, you get a push. Read the full diff, comment inline, approve or send it back — from any screen you're holding. You choose how every session finishes.

  • Full diffs with inline comments, from the phone
  • Explicit finish flow: merge, PR, keep, or discard
  • Every session isolated on its own branch until you say so

One control plane, four agents

Run them side by side — supermux speaks all four dialects and gives you one fleet, one review flow, one way to ship.

No vendor cloud in the middle

supermux runs on hardware you control. Your source, session state, and memory stay on your machine — no account, no analytics, no hosted control plane.

Isolation by default

Every session gets its own git worktree and branch. Nothing touches main until you finish it on purpose.

desktop + mobile + server

Get supermux everywhere.

Install the desktop app, open it, and pair your phone with a QR code. The Mac and Linux apps can host your agent sessions directly; Windows connects as a desktop client. No terminal setup or supermux account required.

The built-in relay lets your devices stay connected away from home without exposing your computer to the public internet. Your agent CLIs, credentials, and work remain on the host you control.
