License

The repository provides the software under the MIT License, which grants permission to use, copy, modify, and distribute it free of charge.Read 7 Oct 2026 · github.com

Build and runtime

The only build dependency is the Rust toolchain, and runtime requires a Unix-like system with a native PTY and a UTF-8 terminal.Read 7 Oct 2026 · github.com

Clipboard

Optional clipboard integration uses wl-copy, xclip, xsel, or macOS pbcopy; remote clipboard image or file uploads have a default 64 MiB limit.Read 7 Oct 2026 · github.com

Clipboard integration

System clipboard integration can use wl-copy, xclip, xsel, or macOS pbcopy, and these tools are optional.Read 7 Oct 2026 · github.com

Compatibility

The documented target is Unix systems with a native PTY and UTF-8 outer terminal; the project says it does not automatically detect GBK or Big5.Read 7 Oct 2026 · github.com

Compatibility limits

The compatibility notes say GBK/Big5 detection, direct TCP listeners, and plugins are outside the current scope.Read 7 Oct 2026 · github.com

Configuration

Configuration supports settings including the default shell, key prefix, scrollback limits, mouse input, refresh rate, and clipboard command.Read 7 Oct 2026 · github.com

Pane controls

Plux supports vertical and horizontal splits, pane focus, zoom, resizing split ratios, and closing panes.Read 7 Oct 2026 · github.com

Pane management

Plux supports vertical and horizontal splits, pane focus, zoom, ratio adjustment, and pane closing.Read 7 Oct 2026 · github.com

Platform limits

The project lists Windows, terminal graphics protocols, and shell restoration after daemon crashes or reboot among its current limits.Read 7 Oct 2026 · github.com

Platform support

The project targets Unix systems with a native PTY and UTF-8 outer terminal; its README says Windows is unsupported.Read 7 Oct 2026 · github.com

Remote access

Remote attach uses SSH as an encrypted bridge and requires a compatible Plux binary on the server.Read 7 Oct 2026 · github.com

Scrollback and search

It provides scrollback, history search, and coordinate selection for copying terminal text.Read 7 Oct 2026 · github.com

Sessions

Named sessions can be detached and reattached, and a new client can take over from the older attached client.Read 7 Oct 2026 · github.com

SSH

Remote attach uses SSH as an encrypted bridge, and the server needs a compatible Plux binary available on PATH or at ~/.cargo/bin/plux.Read 7 Oct 2026 · github.com

Terminal limits

The current implementation does not restore shells after a daemon crash or reboot and does not support terminal graphics protocols.Read 7 Oct 2026 · github.com

Upload limit

The default remote clipboard image and file upload limit is 64 MiB and can be changed with clipboard_upload_max_bytes.Read 7 Oct 2026 · github.com
