Muxin review

Muxin is an open-source desktop app, written in Rust by Lumary Labs, that puts your computers in one window and runs agent CLIs on them. We read the vendor's site, docs and GitHub pages on 12 November 2026. We did not install it or run it, so everything here is the vendor's account.

You add a Mac, Linux box or Windows PC that answers over ssh. According to the docs, Muxin uses your ssh keys and config, installs a small helper there, and starts sessions on it. The README lists twelve agent CLIs, among them Claude Code and Codex CLI. The vendor says sessions keep running on the machine after you close the app, like tmux. Each one shows its branch, changed lines and pull request, and its work can be handed to another agent or machine (Windows machines are not a hand-off target).

More than a terminal

Age and cost

The desktop app is free under Apache-2.0. The repository was created on 8 October 2026, v0.13.0 came out on 10 November, and the GitHub API showed 456 stars on 12 November. It is five weeks old and pre-1.0. The vendor says the apps have no analytics or telemetry, though alerts, shares and pairing pass through muxin.dev. The separate iPad app (iPad only, no iPhone version) has a free demo, but reaching your own machines costs $15 a month in the US, and it is not open source.

Rough edges

The Windows installer is unsigned. On Windows machines, boxes, Docker workspaces, Docker runners and virtual monitors are not available yet, and the desktop view of a Linux machine needs X11. The README says boxes run agents with permission prompts off, inside a container whose network is not restricted, and a box uses your GitHub login, so it can push branches and open pull requests. The home-page FAQ still names six agents; the README and docs name twelve, and boxes support only six of them.

Facts: platforms, price and licence

platforms
macOSWindowsLinuxDesktop app: macOS 12 or later (Apple silicon and Intel, dmg), Windows 11 (x64 and Arm installers and zips), Linux with glibc 2.35 or newer (x86_64 and aarch64: AppImage, deb, rpm, Arch pkg, tar.gz; the vendor site also lists an AUR package (muxin-bin) and a Homebrew cask from the vendor's own tap). The separate Muxin for iPad app is not listed in platforms because the schema has no iPad value: it is iPad only, iPadOS 18 or later (App Store page says 'Compatible with iPad'); no iPhone or Android app was found. The Windows installer is not signed yet (v0.13.0 release notes and the home page). Machines it manages can be Macs, Linux machines and Windows PCs reachable by ssh; remote desktop works on Linux only with X11 (Wayland-only not yet supported).
price
FreeDesktop app for macOS, Linux and Windows: free, open source, Apache-2.0 (site FAQ). Muxin for iPad: free to download with a demo; reaching your own machines needs the Muxin Monthly subscription, $15 a month in the US (site FAQ and iPad docs; the App Store shows local price). All seen 2026-11-12. The desktop app is free; the paid item is only the iPad companion app.

Muxin strengths

  • Free Apache-2.0 desktop app with release assets for macOS, Windows (x64 and Arm) and Linux (x86_64 and aarch64), plus a Homebrew cask from the vendor's own tap
  • Agent sessions (twelve CLIs listed in the README; boxes support six; Windows machines are not a hand-off target) keep running on the remote machine like tmux, with per-session branch, diff and pull request status, notifications, and hand-off to another agent or machine
  • Same capabilities exposed through an MCP server (90+ tools per the site) and a CLI where every command takes --json
  • Reaches machines with your own ssh keys and ~/.ssh/config, including ProxyJump, then installs a small agent there; optional direct QUIC connection and Tailscale; the vendor's privacy page states the apps have no analytics, telemetry or crash uploads (alerts, shares and pairing still go through muxin.dev)

Muxin weak points

  • Very new and pre-1.0: the repository was created 2026-10-08, 22 releases were published from v0.2.0 to v0.13.0 (v0.13.0 on 2026-11-10); a v0.14.0 tag already existed on 2026-11-12, and it was called Muxen before 0.5.1
  • Windows has gaps: the installer is unsigned, and Windows machines cannot yet run boxes, Docker workspaces or Docker runners or get virtual monitors; Linux remote desktop needs X11
  • The iPad app is a separate subscription ($15 a month in the US) and is not open source; it is iPad only, does not read ssh config or use jump hosts, and cannot make VMs or share sessions
  • The README says boxes run agents with permission prompts off inside a container whose network is not restricted, and a box uses your GitHub login so it can push branches and open pull requests; host workspace commands are not sandboxed

Who Muxin is for

best for
People who own several machines (desk Mac, Linux box, Windows PC, cloud VMs) and want to run and watch coding agent sessions on them from one free open-source app, or let their own agents do it through MCP.
look elsewhere if
Probably not the right fit (our reading, not a vendor statement) for anyone who wants a classic SSH/SFTP client with a saved-host library, an iPhone or Android app, or a mature 1.0 product.
