∴ rex

Rex is a terminal kanban for parallel AI coding-agent sessions. Two binaries: rex (CLI and TUI) and rex-daemon (PTY supervisor). You run many agent CLIs at once; Rex tracks state, transcripts, and input prompts.

Requires Go 1.26.10+ to build from source. Targets macOS, Linux, and Windows 10 1809+ / 11.

Install

From a checkout:

./install.sh
export PATH="$HOME/.local/bin:$PATH"
rex setup

Or:

make install PREFIX=$HOME/.local
export PATH="$HOME/.local/bin:$PATH"
rex setup

On Windows (PowerShell, from a checkout):

powershell -ExecutionPolicy Bypass -File .\install.ps1   # installs to ~\.local\bin, adds it to your user PATH
rex setup

Agents run on ConPTY. Claude Code's state hooks need Git for Windows (Claude runs hooks in Git Bash), and the echo test tool needs bash on PATH.

Or without a clone:

go install github.com/tristanbietsch/rex/cmd/rex@latest
go install github.com/tristanbietsch/rex/cmd/rex-daemon@latest

Install both binaries. Put the install directory on PATH.

Use

rex daemon start
rex new "hello rex" --tool echo --model short --slug demo
rex ls
rex status

rex ls prints a session table. rex status prints one summary line. Run rex with no arguments for the board.

Go source wins when documentation disagrees with behavior.
