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.

sysvinit features and specs

  • Simplicity
    SysVinit is known for its straightforward and simple design, making it easier to understand and manage for system administrators who are familiar with its traditional approach.
  • Mature and Stable
    SysVinit has been around for a long time, which means it is well-tested and stable. Many of its behaviors are well-documented, and there is a wealth of community knowledge available.
  • Compatibility
    Due to its long history, SysVinit is compatible with a wide range of Unix-like operating systems, making it a reliable choice for legacy systems.
  • Flexibility
    SysVinit allows users to write custom scripts for managing services, offering flexibility for specialized needs or environments.

Possible disadvantages of sysvinit

  • Lack of Parallelization
    SysVinit does not natively support starting services in parallel, which can lead to longer boot times as it starts services sequentially.
  • Complexity in Large Setups
    Even though SysVinit is simple, managing a large number of startup scripts can become complex and unwieldy as configurations grow.
  • Limited Dependency Handling
    SysVinit has a limited ability to handle dependencies between services, potentially resulting in issues during system startup if services are started in the wrong order.
  • Manual Configuration
    SysVinit requires more manual intervention to manage services, which can be time-consuming compared to more automated solutions like systemd.

Analysis of Command Book

Overall verdict

  • Command Book appears to be a niche productivity tool designed to help users store, organize, and quickly access frequently used commands, scripts, or shortcuts (such as terminal commands, keyboard shortcuts, or code snippets). Without hands-on, up-to-date access to verify current features, pricing, and user reviews, I can't provide a fully verified assessment. I recommend checking recent user reviews, the official site's feature list, and trying any free trial before committing.

Why this product is good

  • Likely helps reduce time spent searching for or re-typing frequently used commands
  • May offer organization features like tagging, categories, or search for quick retrieval
  • Could be useful for developers, sysadmins, or power users who rely on repetitive commands
  • Potentially lightweight and focused, avoiding bloat found in larger note-taking apps

Recommended for

  • Developers who frequently use terminal or CLI commands
  • System administrators managing multiple scripts or configurations
  • Power users who want a centralized reference for shortcuts and commands
  • Teams looking to standardize and share command references
  • Anyone who wants to verify current features and reviews before adopting a niche productivity tool

Questions & Answers

As answered by people managing sysvinit and Command Book.

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.

    It's a plus because Gentoo fully supports the choice of Systemd or OpenRC. It also has minit, dumb-init, sysvinit, cinit in tree for the more adventurous. No one was calling the AUR bloat, the parent comment just mentions that Gentoo has an equivalent project, GURU. Source: about 4 years ago
