p2pmux vs Shpool

p2pmux is a free peer-to-peer terminal multiplexer for connecting people and machines to one shared session. Each pane runs a real shell on the machine of the person who opened it, using that host's tools and environment. Shared sessions can have up to 8 members, 9 tabs, and 8 panes per tab, with nested splits. Terminal streaming is end-to-end encrypted and peer-to-peer, with an iroh relay available when NAT requires it. If the coordinator laptop closes, panes on other machines continue running, but layout changes and new joins pause. Processes and credential files remain on the pane host rather than being uploaded to peers. The agent inbox can show detected coding agents and 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. The project supports macOS and Linux, not Windows. Linux builds require glibc 2.35 or newer, while musl systems must build from source. It is released under the MIT license.

Shpool is free, open-source software for keeping named shell sessions alive when connections drop. It targets users who want persistence without terminal multiplexing features such as split windows or tiled panes, preserving native terminal scrollback and copy-paste. For SSH, Shpool runs on the remote host and needs no additional client software. Users reconnect with `shpool attach`; the terminal state is redrawn after reattachment. The command line can list, detach, or kill sessions, and `--ttl` sets a session lifetime. Variables in session names and attach options can redirect terminals to newly named sessions when values change. Bash, zsh, and fish support automatic session-name prompt prefixes. The README documents SSH configuration, shell-function patterns, Cargo installation through crates.io, and Homebrew installation on macOS. Shpool supports Linux, macOS, SSH, and command-line shells. It is licensed Apache-2.0, reports zero advisories, and allows only one client per session.
