A native tmux for Windows built without knowing C
A developer with no C experience built tmux-win, a native Windows terminal multiplexer on win32 and ConPTY, with Claude Code writing the low-level code.

The full story
The maker wanted tmux on Windows without the overhead of WSL or the mess of Cygwin, but did not know C or low-level win32 programming. The result, tmux-win, is a native multiplexer built on the win32 API and ConPTY, with a client-server design that uses named pipes.
Claude Code handled the win32 structures and process management, and turned the maker's description of how sessions and panes should work into system calls. ConPTY debugging took many iterations before rendering was stable. Vertical and horizontal splits work, and sessions can be detached and reattached.
