What p2pmux is
p2pmux is a free peer-to-peer terminal multiplexer that lets users and machines connect to a shared session. Each pane runs a real shell on the machine of the person who opened it, using that host’s tools and environment. Sessions support up to 8 members, 9 tabs and 8 panes per tab, with shared layouts and nested splits. Terminal streaming is end-to-end encrypted and peer-to-peer; an iroh relay can be used when NAT requires it. If the coordinator’s laptop closes, panes on other machines keep running, although layout changes and new joins pause. Processes and credential files remain on the pane host and are not uploaded to peers. The agent inbox lists detected coding agents and can open a pane for terminal input. Anyone with a join code or ticket can see every pane and interact with terminals. Join codes last six hours; a rendezvous outage can trigger a service-free ticket fallback. The MIT-licensed project supports macOS and Linux, not Windows. Linux builds require glibc 2.35 or newer; musl systems must build from source.
Good
- Shared sessions support up to 8 members.
- Terminal streaming is end-to-end encrypted.
- Processes and credential files stay on pane hosts.
- MIT licensed and free.
Watch out
- Windows is unsupported.
- Join codes or tickets grant control of every pane.
- Linux requires glibc 2.35 or newer.
- Musl systems must build from source.
Who it suits
It suits users who want to share terminal sessions across machines and collaborate in real shells. It is aimed at macOS and Linux command-line users, including those working with coding agents.
Verdict
p2pmux provides shared terminal layouts while keeping processes and credentials on their host machines. Its broad session access makes join-code and ticket handling important, and Windows users cannot use it.
