As answered by people managing Codility and Wallper.
Wallper's answer:
Wallper combines beautiful live wallpapers with native macOS performance. No clunky wrappers, no subscriptions. It just works smoothly and with complete control for every screen.
Wallper's answer:
Most alternatives are either outdated, heavy on resources, or require a login. Wallper is fast, lightweight, fully local, and respects your privacy. Plus, it’s designed specifically for macOS.
Wallper's answer:
Mac users who care about aesthetics, productivity, and simplicity. Creatives, developers, designers - anyone who wants their desktop to feel alive and personal.
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.
Wallper's answer:
Wallper is built entirely in Swift & SwiftUI. Everything is optimized for macOS with no Electron or cross-platform layers.
Wallper's answer:
Used by teams at indie studios and design agencies
