Four courses, four ways to get hit
Each course has its own music, scenery and a hazard borrowed from Mario Kart 64.
Green Hills
Farm fields, cows, barns and the Monty Moles that pop out of the road.
Sunset Speedway
A city highway with traffic: buses and trucks that you have to weave around.
Frosty Peaks
Snowmen to dodge, sheet ice that keeps you sliding, and penguins on the ice.
Dusty Canyon
A desert with a jump ramp and a steam train crossing the road. Wait for it.

Racing feel and items
Racing that feels right
- Powerslides with a hop, and a yellow then red mini-turbo if you toggle the stick.
- Rocket start if you hit the throttle just before the light turns.
- Slipstream: tuck in behind a rival for a burst of speed.
- Rubber-banding AI in Easy, Medium and Hard, with 50cc, 100cc, 150cc and a mirrored Extra class.
- Light, Medium and Heavy karts that really do shove each other differently.
- Lakitu starts the race, shows your lap and fishes you out of the water.
14 items. Zero fairness.
Mushrooms, bananas, green and red shells, triple shells, the blue spiny shell, a star, lightning, a fake item box and a Boo. Hold a banana behind you as a shield, fire shells backwards, or toss bananas ahead.
Every icon is drawn from a few polygons and circles in code.
Race your friends online
Up to 4 players over the internet, on any mix of macOS, Windows and Linux. Everyone needs the same GoKart version.
1. Open the ONLINE screen
Press O on the select screen and type your name. It's saved, and it floats above your kart in everyone else's game.
2. Quick Match
Drops you into any open public room. The race starts 20 seconds after a second player joins, or right away once 4 are in.
3. Or a private room
Create a room to get a 4-letter code on the course you picked, and send it to your friends to Join. The host presses START NOW when 2 or more players are in.
4. Race
3 laps with item boxes on. Shells, bananas and fake boxes show up in every game, the results board updates live, and you'll see a notice if someone leaves.
How it works
- Peer-to-peer. gokart.games only runs a small lobby that groups players into rooms and passes along the connection handshake. The race itself goes straight between the games over WebRTC, with no game server in the middle.
- Your kart, your call. Each game drives its own kart and sends its position about 30 times a second. Other karts are shown 0.1 s behind so they move smoothly, and the host syncs the 3-2-1 start.
- Fair hits. Your game rolls and fires your own items. When something hits you, your game decides it, so you never get spun by a shell that missed on your screen.
- Finish order comes from each player's own race time.
If you can't connect
Players find each other through public STUN servers (Google and Cloudflare). There is no relay server yet, so a very strict firewall or router (symmetric NAT, some office and mobile networks) can stop two players from connecting. Trying a different network usually helps.
On Windows and Linux, keep the libwebrtc_native file next to the game: online play needs it. On macOS it's inside the app.
Platforms
The same code runs on all of them, and players on different systems race each other online. No Godot install needed: macOS is one app, and Windows and Linux are the game plus the small online-play library that sits next to it.

Built by an AI agent, in the open
GoKart was written by Agent! running Auto-Pilot on one goal: make a Mario Kart clone. Every track, kart, effect and sound is generated from code, and the repo carries a unit suite of over 14,000 checks. The blog post tells the whole story, including where it got stuck.
GoKart is an independent fan project inspired by Mario Kart 64. It is not affiliated with or endorsed by Nintendo.
