Platforms

Host clients attach to sessions kept by ubiquitty-host. The macOS app can also run its own shell; the Linux GTK frontend runs local shells only. The table distinguishes transports and rendering support. See Install and build for prerequisites and commands.

macOS	Local PTY, Local host socket, SSH, QUIC	Yes	Yes
iPhone and iPad	SSH, QUIC	No	Yes
Linux	Local PTY	Yes	No
Web browser	WebSocket (development bridge)	No	Yes
ubq and agents	Local host socket, SSH	No	Yes
UbiquittyKit	Embedder's PTY, Local host socket, SSH, QUIC	Yes	Yes
Emacs	Host attach bridge	No	Yes
Neovim	Host attach bridge	No	Yes

Transport is how the client reaches a session. Local host socket is the host’s owner-only Unix socket on the same machine. Host attach bridge runs ubiquitty-host --attach and talks over its standard input and output. SSH runs the host on another machine over your SSH connection; QUIC then carries the session after SSH has authenticated it. Depends means the embedding application draws, and decides.

The host

ubiquitty-host. The daemon every client attaches to. It owns the shells, the panes and the layout, and keeps them when no client is attached. Runs on macOS; static Linux builds for x86_64 and arm64; other POSIX systems from source. See Multiplexer and sessions.
