Walyro is a live wallpaper app for Mac. Instead of pulling from an online gallery, it turns your own videos into animated desktop wallpapers and keeps everything on your device.
Drop in an MP4 or MOV and it plays as your background, up to 4K. You can preview a clip on each display before applying it, build playlists that rotate on their own, and control each screen from the menu bar or a Now Playing widget in the sidebar. A few built-in videos are there if you want something running in one click.
What it does
It's a native Swift and SwiftUI app, not an Electron wrapper, so it stays light. Playback pauses when an app goes fullscreen and eases off on battery or Low Power Mode.
Your library never leaves the Mac. No cloud storage, no account.
Walyro is free to download. No subscription.

Most Mac wallpaper apps hand you a gallery to browse. Walyro starts from your own footage instead. You point it at your MP4 or MOV clips and it plays them as live wallpapers up to 4K, with a different one on each display. The whole library stays on your Mac, with no online catalog, no account, and no tracking. It's a native Swift and SwiftUI app, so it pauses on fullscreen and eases off on battery to stay light on the CPU.
Walyro's answer:
Choose Walyro if you want your own videos on your desktop rather than a prebuilt gallery, and if you'd rather keep everything on your Mac. Nothing uploads, there's no account, and there's no subscription: you download it free and pay once to unlock the full app. It still covers what the others are known for, per-display wallpapers, up to 4K, and playlists that rotate on their own, while staying native and light on the CPU. If what you want is a large online catalog of ready-made wallpapers, a gallery-first app may suit you better. Walyro is for people who want to use their own clips.
Walyro's answer:
Mac users who want their desktop to feel personal and who care about keeping files on their own machine. That includes people coming from Wallpaper Engine on Windows who want a native Mac option, multi-monitor setups that want a different scene on each screen, and anyone with their own clips (footage they shot, renders, or edits) who would rather use those than pick from a stock library. The common thread is wanting control over the wallpaper without sending anything to the cloud.
Walyro's answer:
I wanted my own videos living on my desktop without uploading them to someone's cloud or making yet another account. The Mac apps I tried were built around their own galleries, and Wallpaper Engine, the app people always point to, doesn't run on Mac at all. So I built the one I wanted: point it at your own clips, keep the whole library on the device, and make it feel native instead of a web wrapper. That starting point shaped the rest, from previewing each display before you apply a wallpaper to pausing playback the moment you go fullscreen or switch to battery.
Walyro's answer:
Walyro is a fully native macOS app, with no Electron or other cross-platform runtime. It's written in Swift with SwiftUI and AppKit for the interface, Combine for state, and AVFoundation and AVKit for video playback. In-app purchases use StoreKit 2, and launch-at-login uses ServiceManagement.
Walyro's answer:
Walyro is a consumer app used by individual Mac users, so there are no named business customers to list.
