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.

ExpressJS features and specs

  • Fast Setup
    ExpressJS provides a minimal and flexible framework that allows rapid setup and development of web and mobile applications.
  • Middleware Support
    ExpressJS has a robust middleware system, allowing developers to add reusable functions to the request-handling pipeline.
  • Extensibility
    ExpressJS is highly extensible through third-party libraries and built-in functionality, catering to the needs of various applications.
  • Performance
    Due to its minimalist core, ExpressJS provides efficient performance and is capable of handling a high number of requests per second.
  • Community and Ecosystem
    A large and active community provides extensive documentation, support, and a wide array of open-source packages to extend functionality.
  • Flexibility
    Compared to full-stack frameworks, ExpressJS gives developers the freedom to structure their applications as they see fit.
  • Compatibility
    ExpressJS works seamlessly with various template engines, databases, and other frameworks, making it versatile for different project requirements.

Possible disadvantages of ExpressJS

  • Minimalist Core
    The minimalist nature of ExpressJS may require additional time and effort to integrate required plugins and libraries for specific features.
  • Learning Curve
    While ExpressJS is straightforward, mastering the middleware pattern and effective usage can have a learning curve for new developers.
  • Callback Hell
    Developers can encounter 'callback hell' due to nested callback functions, though this can be mitigated using Promises and async/await in modern JavaScript.
  • Lack of Convention
    Unlike opinionated frameworks, ExpressJS lacks conventions, which can lead to inconsistent code structure and maintenance challenges across different projects.
  • Security
    ExpressJS does not have built-in security features and relies on third-party solutions, requiring developers to be vigilant about applying best security practices.
  • Scalability
    While ExpressJS can handle high traffic, building and maintaining a highly scalable application might require significant additional effort, particularly in terms of codebase organization and resource management.

Overall verdict

  • ExpressJS is a highly recommended option for building web applications with Node.js. Its simplicity, extensive middleware options, and strong community support make it a solid choice for both beginners and experienced developers. However, it might not be the best fit for highly complex applications that require more opinionated frameworks with more built-in features.

Questions & Answers

As answered by people managing ExpressJS 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.
