Features and specs

What each product offers, as listed by its team.

ViewSource.net 5 features
Rectangle 5 features
  • Convenient browser-based access
    I can't browse the site or verify its contents. If ViewSource.net is an online tool for inspecting the HTML/source of web pages, as the name suggests, it would let users inspect a page's source without installing software or using browser developer tools.
  • Useful for learning and debugging
    Online source-viewing tools generally help beginners see how web pages are built and help developers debug markup. Confirm that this site offers these capabilities.
  • No local setup required
    Web-based utilities usually work on any device with a browser, including phones and locked-down computers where dev tools may be unavailable or inconvenient.
  • Potentially simple interface
    Single-purpose tools tend to have a minimal, focused interface that is quick to learn. I have not verified this for ViewSource.net, so check it yourself.
  • Fetching from a remote server
    If the site fetches pages server-side, it may show the raw source without client-side scripts altering it. This can help when inspecting how a page looks to crawlers or other clients.
  • Ease of Use
    Rectangle offers an intuitive user interface that makes window management straightforward and user-friendly.
  • Customizable Shortcuts
    Users can easily configure keyboard shortcuts to better suit their workflow, making window management faster and more efficient.
  • Free
    Rectangle is available for free, making it accessible to anyone without the need for a financial investment.
  • Frequent Updates
    The app receives regular updates, introducing new features and ensuring compatibility with the latest macOS versions.
  • Lightweight
    Rectangle is a lightweight application that doesn't consume many system resources, ensuring smooth performance even on older Macs.

Possible disadvantages

  • Limited Advanced Features
    Rectangle lacks some of the more advanced features found in paid window management applications, such as multiple monitor support and more complex window arrangements.
  • MacOS Only
    Rectangle is only available for macOS, so users of other operating systems are unable to take advantage of its features.
  • Occasional Bugs
    Some users report occasional bugs or unpredictable behavior, which might require troubleshooting or waiting for a future update.
  • Learning Curve for Shortcuts
    While customizable shortcuts are a benefit, there is an initial learning curve for users to memorize and effectively use these shortcuts.
  • Basic Aesthetic
    The app's design and aesthetic are quite basic, lacking the polish and visual appeal found in some other similar tools.
