Open-Source Alternatives to Mario Kart: SuperTuxKart and More

Mario Kart has been the benchmark for arcade racing since 1992, and it is still the game every kart racer gets measured against. But the formula underneath it — cartoon drivers, weapon pick-ups, drifting round impossible corners, four friends on one screen — is not something Nintendo owns. The free and open-source world has been building its own versions for twenty years, and a few of them are genuinely good. Here is what you can play instead, what each one actually does well, and how they compare to the blue shells and banana peels you are used to.

What Makes a Kart Racer Work

Strip Mario Kart back and there are only four things that matter: readable tracks, tight controls, a weapon system that creates chaos without deciding the race outright, and local multiplayer that does not fall apart the moment someone takes the lead. That is a surprisingly short list, and it is why the open-source options split so cleanly — some nail the arcade feel, others go straight for simulation and physics, and one or two do something else entirely in a racing skin.

SuperTuxKart — The Closest Thing to Mario Kart

SuperTuxKart is the obvious first answer and the one that actually delivers the Mario Kart experience. It has been in development since 2004, it is in the repositories of nearly every Linux distribution, and it runs on Windows, macOS, Linux, Android and iOS. You race cartoon characters — Tux and friends — around themed tracks, collecting power-ups and weapons to knock rivals off the road.

• Game modes that mirror the original — Grand Prix, Time Trial, single races, and a football mode the game calls Soccer. Egg hunts and a benchmark mode arrived with version 1.5 as well.
• Multiplayer both ways — four-player split-screen on one machine, plus online and LAN play when you want a bigger grid.
• Adjustable difficulty — the AI scales from easy enough for a child to genuinely testing, so it works as a family game and as a challenge.
• Light on hardware — it runs smoothly on modest machines and integrated graphics, which is more than can be said for most modern racers.
• Free in every sense — the code is GPL-3.0 and the artwork uses Creative Commons licences. No ads, no in-app purchases, no telemetry, and it works fully offline.

The current stable release is SuperTuxKart 1.5 (October 2025), and the project has announced SuperTuxKart Evolution as its next major version, described as the biggest content release in the game’s history. See the SuperTuxKart listing for the full feature breakdown, or download it from the official site.

Extreme Tux Racer — Arcade Downhill Racing With Tux

If what you like about Mario Kart is the speed and the arcade feel rather than the karts specifically, Extreme Tux Racer is the next stop. Tux belly-slides down snow and ice courses, weaving between trees and rocks, grabbing herring along the way, and crossing the finish line before the clock runs out. It continues the original Tux Racer by Jasmin Patry from 2000 through the PlanetPenguin Racer fork, and has been maintained by the Extreme Tux Racer team since 2007.

• Terrain actually matters — ice is fast but slippery, snow gives you grip, and rocky patches or a tree cost you speed. The course physically changes how Tux handles.
• Two ways to play — Practice for a free run on any course, and Events, where you unlock the next track by finishing high enough.
• A full move set — steer, brake, jump, paddle for extra ground speed, and flap in mid-air to stretch a jump.
• Editable courses — tracks ship as plain data directories, so you can tweak the bundled ones or build your own.
• Very light on hardware — a small OpenGL/SDL engine that stays smooth on old laptops and even single-board computers.

Version 0.8.4 is current, shipping as extremetuxracer in Debian and Ubuntu and as a Flatpak on Flathub. It is GPL-2.0, with native builds for Windows, macOS and Linux. See the Extreme Tux Racer listing.

Armagetron Advanced — Tron-Style Lightcycle Racing

Not a kart game, but one of the purest arcade racers on Linux. Armagetron Advanced is the “Tron clone in 3D” whose tagline it has carried from the start: you ride a lightcycle that never stops and never slows down, turning only at right angles and leaving a solid wall of light behind you. Touch any wall and you are out; the last cycle moving wins the round.

• Authentic lightcycle physics — no braking, lethal trails, and a “rubber” grace period that a server can tune from twitchy duels to forgiving arenas.
• Online multiplayer built in — an in-game server browser lists public servers by name, mode and player count. No account, no matchmaking queue.
• Host your own server — a headless dedicated server binary ships for Linux, macOS and Windows, so a persistent community server can run on a small box.
• Actively developed — version 0.2.9.3.1 landed in October 2026, with commits in the same month.

It is GPL-2.0, and if you have ever lost an evening to a lightcycle arena, this is the best version of it. See the Armagetron Advanced listing.

Speed Dreams and TORCS — When You Want Real Racing Physics

Mario Kart deliberately throws physics out of the window. If you want the opposite — a racing game where the tyre model is the point — the open-source world has two long-running simulators worth knowing about.

Speed Dreams started in 2008 as a fork of TORCS and has grown into one of the most complete open-source racing sims: 82 finely tuned cars in 16 balanced sets, 21 high-quality tracks, several selectable physics engines, four distinct AI opponent implementations, a career mode spanning multiple seasons, real-time weather, and support for racing wheels with pedals. It can even run headless for AI research. See the Speed Dreams listing.

TORCS — The Open Racing Car Simulator — predates it, starting in 2000, and ships 114 circuits alongside a documented Robot Module Interface that lets custom AI drivers read the full simulation state and control steering, throttle, brake and gears. Like Speed Dreams it supports headless batch racing, which is why both have spent two decades as teaching and research tools as well as games. See the TORCS listing.

Neither is a Mario Kart replacement, and neither pretends to be. They are what you graduate to when the arcade handling stops being the fun part.

X-Moto — 2D Physics Motorcycle Trials

Worth a mention for the same reason Armagetron is: it is a racing game where the challenge is mastery rather than speed alone. X-Moto puts you on a motocross bike seen from the side, balancing throttle, brakes and body rotation across levels built from floating islands, collecting every strawberry before touching the sunflower to finish. Two decades of user-made levels, in-game world-record lists, replay recording, and a level editor built on Inkscape and SVG. See the X-Moto listing.

Multiplayer and Self-Hosting

This is where the open-source options beat the console original outright. SuperTuxKart ships split-screen for four players on one machine and supports online and LAN play without an account or a subscription. Armagetron Advanced has a proper dedicated server binary you can run yourself. All of these games require no vendor account, no phone-home check, and no subscription — and several of them can keep running on hardware a modern console would never touch.

How to Choose

• You want Mario Kart, free, today: SuperTuxKart. Install it, race a Grand Prix, and you will forget you are not on a Nintendo system.
• You want a party game for one screen: SuperTuxKart split-screen, four players, one PC.
• You want arcade speed without karts: Extreme Tux Racer for downhill, Armagetron Advanced for lightcycles.
• You want to learn to race properly: Speed Dreams, then TORCS when you want to write your own AI driver.
• You want a five-minute skill challenge: X-Moto.

The Bottom Line

There is no single “open-source Mario Kart”, but SuperTuxKart comes remarkably close: it has the karts, the weapons, the split-screen and the online play, and it is free under the GPL with no catch attached. Extreme Tux Racer is the pick when you want the arcade thrill with a lower hardware bar, and Armagetron Advanced is the one to play when you want a racer that feels like nothing else. Together they cover almost every reason someone goes looking for a Mario Kart alternative — no console, no licence fee, no lock-in, and a game you actually own.
