## What it is
ScreenCat is an open-source Electron app for screen sharing and remote collaboration over WebRTC, letting a remote user view your desktop and control your mouse and keyboard. It supports connecting from a normal browser via an invite code, using Chromium's screen media source and a small lobby server for signaling.

## Use cases
- share my screen with someone over webrtc
- let a colleague remotely control my mac mouse and keyboard
- free open source screen sharing app for mac
- remote desktop support via browser without installing client
- pair programming with shared screen and remote input

## When to choose
- you want an open-source, self-hostable alternative to commercial screen sharing on macOS
- the remote viewer should connect from a plain browser with just an invite code
- you want to hack on or fork a WebRTC screen sharing app

## When to avoid
- you need a polished, production-ready remote desktop tool
- you need Windows or Linux support out of the box
- you expect active maintenance - the project is alpha status and last released in 2016
