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 ⌘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.

Alacritty features and specs

  • Performance
    Alacritty is known for its excellent performance and speed, leveraging GPU acceleration to deliver a faster terminal experience compared to many other terminal emulators.
  • Simplicity
    Alacritty aims to be simple and focuses on providing a straightforward terminal experience without unnecessary features. This makes it easier for users who prefer minimalistic design.
  • Cross-Platform
    Alacritty is cross-platform, supporting various operating systems including Linux, macOS, and Windows, which makes it versatile for users across different environments.
  • Customizable
    Despite its simplicity, Alacritty offers a range of configuration options through a YAML file, allowing users to tweak the terminal to their preferences.
  • Active Development
    The project is actively maintained, ensuring that it receives regular updates, new features, and bug fixes.

Possible disadvantages of Alacritty

  • Lack of Native Tabs and Splits
    Alacritty doesn't natively support tabs or splits, which might be a limitation for users who rely heavily on these features in other terminal emulators.
  • Configuration Complexity
    While the configuration is powerful, it uses a YAML file which might be intimidating for beginners who are not familiar with YAML syntax.
  • Limited Out-of-the-Box Features
    Alacritty's philosophy of simplicity means it lacks some advanced features available in other terminal emulators, such as built-in SSH integration and terminal multiplexing.
  • No GUI for Configuration
    Alacritty does not offer a graphical user interface for configuration, which may be a drawback for users who prefer a more visual approach to setting up their terminal.
  • Potential GPU Compatibility Issues
    Since Alacritty relies on GPU acceleration, some users may encounter compatibility issues or suboptimal performance on specific hardware or driver configurations.

Analysis of Alacritty

Overall verdict

  • Yes, Alacritty is considered a good terminal emulator for those who prioritize speed and efficiency. Its minimalist design and modern features meet the needs of users who demand high performance from their terminal applications.

Why this product is good

  • Alacritty is well-regarded because it is a GPU-accelerated terminal emulator, which makes it extremely fast and efficient. It is also lightweight, open-source, and cross-platform, supporting macOS, Linux, and Windows. The emphasis on simplicity and performance, along with a focus on providing a seamless and snappy user experience, makes it a popular choice among developers and power users.

Recommended for

    Alacritty is recommended for developers, programmers, system administrators, and power users who need a fast and reliable terminal emulator that can handle demanding workloads efficiently. It is particularly suitable for those who appreciate minimalism and prefer customizable environments.

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 Alacritty 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.

  • Faking the tmux experience on Windows using AutoHotkey
    I chose Alacritty for this. Why? Because it's written in Rust. Is there any other reason? It also has a pretty simple and has an easy to understand settings page and uses TOML. It also has built in support for vi motions. All wins. It's pretty easy to install as well, just follow the link above. I went with the portable version. Just make sure you note where it is going to look for the configuration files. - Source: dev.to / almost 2 years ago
