A space tocode together.
Jump into an open space
Public coding and chill rooms are visible here so logged-in people can discover active spaces.
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.
Coding Rooms
Create a coding-type room with a GitHub repo link. Walk into the Pair Programming Pods zone and press E to open the repo. Pair program, review PRs, or grind DSA together.
Watch Together
Enter the Watch Hall or Review Theater and hit E to jump into the watch room. Everyone's video stays frame-perfect with auto-sync correction every few seconds.
Getting started
Create a Room
Pick Coding or Chill. Add a GitHub link for coding rooms.
Share the link
Anyone with the code or link can join instantly.
Enter the Space
Navigate with WASD. Walk into zones to see what they do.
Collaborate
Talk to nearby people, code together, or watch videos in sync.
Works With Your Media
Drop in links or files from the platforms you already use.
No noisy dashboard here. Just bring the video source you have, and RatCat keeps playback clean and in sync.
Everything in one space. All together.
A 2D virtual world with proximity voice, synced video, coding rooms, and real-time chat — built to feel like being in the same room.
