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.

Supervisor features and specs

  • Ease of Installation and Configuration
    Supervisor is relatively simple to install and configure, even for those who may not have extensive background experience. The configuration files are straightforward, making it easier to manage processes.
  • Web-based UI
    It offers a web-based user interface to monitor and control processes, which can be a convenient way to visually manage operations without using the command line.
  • Process Management
    Supervisor allows users to start, stop, and restart processes programmatically and automatically, ensuring processes are running and are restarted if they unexpectedly stop.
  • Extensive Language and Application Support
    Supervisor works independently of the programming language or application, making it a versatile tool for managing a variety of applications and services.
  • Event Notification
    It provides an event notification system, allowing administrators to be notified of state changes or failures, thus improving responsiveness to operational issues.

Possible disadvantages of Supervisor

  • Python Dependency
    Supervisor requires Python to run, which might be a drawback in environments that do not use Python or have restrictions on adding new dependencies.
  • Limited Built-in Security Features
    By default, Supervisor does not include extensive security features for its web interface, which could be a concern in environments requiring robust security measures.
  • Single Host Management
    Supervisor is designed for process control on a single server, so it may not directly support distributed systems or environments requiring multi-host orchestration.
  • Lack of Built-in Process Dependency Management
    Supervisor does not handle dependencies between processes directly, which might necessitate additional scripting or configuration management to ensure proper start order.
  • Resource Intensive for Very Large Number of Processes
    Although generally efficient, managing a very large number of processes with Supervisor may become resource-intensive, which could impact performance.

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 Supervisor 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.

  • Replacing cron jobs with a centralized task scheduler
    Is there a cool lightweight alternative to cron for (at least) a single host? To illustrate what I am looking for, I often end up using supervisord [0] (but I also like immortal [1]) for process control when not on a systemd enabled system. In my experience they are reliable, lightweight and a pleasure to work with. I am looking for something similar for scheduled jobs. - [0] https://supervisord.org/. - Source: Hacker News / 12 months ago

    Supervisor is a powerful process control system widely used to manage background processes.
