Apps similar to shpool include tmux, which is free and open source. Other options are Herdr, WezTerm, GNU Screen and RMUX. You can choose from more than 10 Terminal Emulators like shpool for Linux, Mac and Windows.
tmux is a terminal multiplexer: it enables a number of terminals (or windows), each running a separate program, to be created, accessed, and controlled from a single screen. tmux may be detached from a screen and continue running in the background, then later reattached.
Handle multiple coding agents in real terminals with instant status tracking, persistent sessions that survive disconnects, SSH/mobile reattachment, keyboard and mouse controls, plugin support, and lightweight operation as a Rust binary for enhanced workflows.

dtach is a tiny program that emulates the detach feature of screen, allowing you to run a program in an environment that is protected from the controlling terminal and attach to it later. dtach does not keep track of the contents of the screen, and thus works best with programs...
abduco provides session management i.e. it allows programs to be run independently from their controlling terminal. That is programs can be detached - run in the background - and then later reattached. Together with dvtm it provides a simpler and cleaner alternative to tmux or...
