There while you work.

SIDEY stays at the edge of your screen while you work. Glance over to see what your friends are up to, and say something when they cross your mind.

  1. Keep doing what you're doing

    You can keep clicking and using the app behind SIDEY like you normally would.

  2. See what they're up to

    Walking, dozing, and sleeping show whether your friends are around.

  3. Say something when you want

    Open SIDEY to send a short message or trade a small bit of mischief.

Standing still would be boring.

Friends walk when they're online, doze when they're away, and sleep when they're offline. You can mess with each other a little, too.

Everyday presence

Walking, dozing, sleeping.

Online, away, or offline—their character changes with their presence.

Bring SIDEY to your desktop.

SIDEY is available for macOS and Windows. Pick the version that matches your computer and install it.

Questions you might have.

A few things worth knowing before you start.

What is SIDEY?

SIDEY is an invite-only desktop messenger where your closest friends hang out along the edge of your screen as tiny pixel characters. Each private group can have up to 12 people.

Which computers are supported?

SIDEY runs on Apple silicon Macs with macOS 26 or later, and x64 PCs with Windows 11 25H2 or later. Intel Macs are not currently supported.

How do I invite friends?

Create a private group and send the invite code directly to your friends. A group can have up to 12 members, and each person can join up to five groups.

Does SIDEY watch what I do on my computer?

No. SIDEY does not collect your screen, open apps, keystrokes from other apps, pointer location, files, microphone, or camera. Typing status is only sent while you type in SIDEY's own message box.

How long are messages kept?

Recent messages are kept for three days, then permanently deleted.

Will SIDEY show over every game and fullscreen app?

Not always. SIDEY stays visible during normal desktop use, but it may not appear over secure screens, DRM-protected apps, elevated apps, or some exclusive-fullscreen games.
