Things to Explore

More than a watch party. A virtual space.

RatCat is a 2D world you can walk around in. Code together, watch videos in sync, and talk to nearby people — all in one place.

2D Virtual Space

Walk around a virtual office or lounge using WASD or arrow keys. Different zones have different vibes — standup areas, pair programming pods, and chill corners.

Proximity Voice

Voice chat activates automatically when you walk close to someone. Move away to fade out. No buttons, no joining channels — just walk up and talk.
