Possible disadvantages

  • Dependency on Internet
    Since the tool is web-based, it requires an internet connection, which may not be available in all situations, potentially limiting accessibility.
  • Scope Limited to Operators
    The tool focuses solely on JavaScript operators, which might not cover all the needs of a developer looking for comprehensive JavaScript resources or help with other language features.
  • Potential for Outdated Information
    There is a potential risk of the information becoming outdated if the tool is not regularly maintained and updated to reflect the latest changes in the JavaScript language.
  • Lack of Interactive Examples
    While the tool provides examples, the absence of interactive coding environments means users cannot test operators directly within the tool.
  • Multi-Monitor Support
    Automatically spans and manages live wallpapers across multiple displays with individual control per screen.
  • Battery-Aware Mode
    Optionally pause wallpapers when on battery and resume automatically when plugged in.
  • Display Manager

What's the story behind your product?

Wallper's answer:

Wallper started as a weekend project. After switching from Windows, we couldn’t believe how limited macOS was when it came to live wallpapers — there just wasn’t a clean, native solution like Wallpaper Engine. We built the first version just for ourselves, to bring our desktops to life again. But as we shared it with friends and online communities, it quickly turned into something much bigger. What began as a personal fix is now a fully featured app used by thousands of Mac users around the world.

Which are the primary technologies used for building your product?

Wallper's answer:

Wallper is built entirely in Swift & SwiftUI. Everything is optimized for macOS with no Electron or cross-platform layers.
