Cocon
A rainy window is one of the most pleasant things to have in the corner of your eye while you work. On a Mac, there are three common ways to get one. They are not equal: the difference is mostly about where the rain lives on your screen, and what it costs.
1. A rain video in a window
The simplest option: open one of the many long “rain on a window” videos, put it in a browser window or a small player, and let it run.
Good: free, endless choice of scenes, sound included.
Less good: the video needs a window, and that window is either in front of your work or hidden behind it. Video decoding in a browser keeps the processor busy, which shows on a laptop battery. Ads can interrupt at the worst moment. And a video loops: after an hour you start to recognise the same thunderclap.
Best for: the occasional evening session on a desktop Mac plugged into power.
2. A live (video) wallpaper
Several apps let you set a video as your desktop wallpaper. The rain is now behind all your windows, which is much better.
Good: the scene stays out of the way of your work; some apps pause the video when a full-screen app covers it.
Less good: it is still a video. It replaces your wallpaper rather than adding to it, it plays the same clip over and over, and the picture does not react to anything — there is no “a bit more rain” or “a bit less”. Sound is often a separate concern, or absent.
Best for: people who want a specific scene as a wallpaper, and are happy to change their background for it.
3. An overlay drawn behind your windows
The third approach is what Cocon does. Instead of playing a video, it draws the rain live on the GPU in a transparent layer that sits just above your own wallpaper and below every window. Your desktop stays your desktop, with rain falling over it.
Good:
- Never in front of your work. Every window you open covers it. It never takes a click.
- Your own wallpaper stays. The rain falls over whatever background you already have.
- It reacts. One slider moves from drizzle to downpour, and the sound follows: Cocon moves between real rain recordings instead of turning one up.
- It does not loop. Drops, gusts and splashes are generated as they fall, so the scene never repeats exactly.
- It rests when hidden. When a full-screen app covers the desktop, or the screen sleeps, drawing pauses.
Less good: the scene is always “over your desktop” — it is not a photograph of a rainy street. And it is a Mac-only app (macOS 14 and later).
Best for: long working days, laptops, and anyone who wants the rain to be part of the room rather than something to watch.
What about sound only?
If you mostly need to cover noise, a sound alone can do the job, and many apps and sites offer rain sounds. The visual adds something different: a sense of place when you look up from the screen, and a reason for the sound to be there. If you are curious why steady sounds like rain help at all, see why the sound of rain helps you focus.
Trying it
Rain, Snow and Fireplace are free in Cocon, with a volume control. Storm — lightning that lights up the sky and thunder that follows each strike — is part of Cocon Pro, and you can preview it for 30 seconds before deciding.
