psmux — psmux brings native tmux functionality to Windows, built in Rust for high performance.

Analyzed by · Developer Tools · CLI · View on GitHub

What It Is

psmux is a terminal multiplexer for Windows, much like 'tmux' is for Linux and macOS. It allows you to run multiple terminal sessions within a single window, splitting it into panes and tabs, and detaching/reattaching to sessions without losing your work. Unlike other solutions, psmux is built natively in Rust for Windows, avoiding the need for WSL, Cygwin, or other compatibility layers.

This matters because it brings a powerful and familiar developer workflow to Windows users who often juggle multiple command-line tasks. It solves the pain point of context switching, losing terminal state, or being forced into less efficient workflows when working on Windows. For developers, it means a more productive and organized terminal environment.

Sai Pavan Gopularam's Take

As an immigrant founder, I appreciate tools that bridge OS gaps and solve real developer pain. psmux is a solid native tmux for Windows, saving countless developers from clunky workarounds. A premium plugin manager or cloud sync service for this could easily fetch $10/month per user.
