panex

A terminal UI for running multiple processes in parallel. Like Turborepo's TUI, without the monorepo.

Features

- Split-pane TUI - See all your processes at once
- Full PTY support - QR codes, colors, interactive prompts work
- Scroll pinning - Freeze output to inspect, toggle with g
- Zero config - Just pass commands as arguments
- Cross-platform - macOS, Linux, Windows
- Native binary - Fast startup, no runtime dependencies
- Wrapped lines - Optional line wrapping per pane (:w label suffix)
- Interactive mode - Focus a pane for full interactivity (with Mouse support)

Installation

``bash


Run directly with npx or bunx

npx panex "npm run api" "npm run web"
bunx panex "bun run api" "bun run web"

Or install globally

npm install -g panex
`

Usage

$3

`bash


Run multiple commands

panex "npm run api" "npm run web" "npm run mobile"

With custom names

panex -n api,web,mobile "npm run api" "npm run web" "npm run mobile"

Full key passthrough for TUI apps (append ! to name)

Esc and Shift-Tab forwarded to process, click left panel to exit

panex "tui" "npm run dev" -n "tui!,server"

Enable line wrapping (append :w to name)

panex "npm run build" -n "build:w"

Combine suffixes (either order works)

panex "helix" "npm run build" -n "helix!:w,build:w"

Custom shutdown timeout (default: 500ms)

panex -t 1000 "npm run dev" # 1 second graceful shutdown
