Command Book is a native macOS app built with SwiftUI that gives your long-running terminal commands a permanent home. Instead of juggling terminal tabs for dev servers, background workers, Docker containers, and log tails every morning, Command Book lets you save each command once with its working directory, environment variables, and pre-commands, then run them instantly whenever you need them.

The app includes auto-restart on crash (nicknamed "Honey Badger mode") to keep dev servers running through file change errors, a โŒ˜K command palette for keyboard-first workflows, automatic URL detection that keeps your dev server addresses accessible regardless of output scrolling, and a full CLI for running saved commands directly from the terminal. At 21 MB with no Electron or Chromium, it stays lightweight and fast.

Free personal license available. Pro edition is a one-time $14.99 purchase with no subscription, no account required, and no tracking. No VC, no enterprise upsell. Feedback welcome. Windows version is under consideration.

Questions & Answers

As answered by people managing Command Book and iTerm2.

Which are the primary technologies used for building your product?

Command Book's answer

Swift and SwiftUI for a fully native macOS experience.

What makes your product unique?

Command Book's answer

Command Book is a dedicated command/process manager for developers, not a terminal emulator. Instead of replacing your terminal, it works alongside it as a companion for long-running commands. It's a native macOS app built with SwiftUI at just 21 MB. No Electron, no Chromium. It combines a GUI with a full CLI, so you can manage commands visually or from your terminal.

Why should a person choose your product over its competitors?

Command Book's answer

Terminal emulators are great for interactive work but terrible as process managers. Command Book fills that gap. You save a command once with its working directory, env vars, and pre-commands, then run it forever without remembering the setup. Auto-restart keeps crashed dev servers running. URL detection means you never lose track of your dev server's address. And at 21 MB with no subscription or tracking, it's lightweight in every sense.

How would you describe the primary audience of your product?

Command Book's answer

Developers who juggle multiple long-running processes every day. Web developers running dev servers and background workers, data scientists kicking off training runs, DevOps engineers managing Docker containers and log tails. Anyone who opens 4-6 terminal tabs each morning just to get their environment running.

What's the story behind your product?

Command Book's answer

After years juggling commands for dev projects, I was tired of rebuilding my terminal setup every morning. Five or six tabs, each needing the right directory and env vars, and when something crashed mid-day I'd hunt through tabs to find it. I looked for a tool that managed long-running commands as saved, reproducible, auto-restarting processes. It didn't exist, so I built it for myself. It was such a delight, I turned it into a product.
