SuperTuxKart is the best free alternative to Mario Kart: a free, open-source kart racer with power-ups, four-player local split-screen, online multiplayer and a story mode, available on Windows, macOS and Linux.
Mario Kart requires Nintendo hardware. The free option runs on any PC, supports split-screen for four players locally, and includes a full campaign plus online racing.

SuperTuxKart is a free, open-source kart racer with power-ups, drifting, local split-screen multiplayer, online racing and a story mode. It is the closest free equivalent to Mario Kart that exists.
How it differs from Mario Kart: Open-source mascots rather than Nintendo characters, and handling is slightly floatier. Track design is strong but does not match Nintendo's polish.

SuperTuxKart is the kind of free game that's impossible not to recommend. It's instantly accessible, genuinely fun with friends, packed with tracks and modes, and backed by a surprisingly active community creating new content.
For the same couch-competitive chaos in a turn-based form, Hedgewars is the other great local-multiplayer pick.
The difference: Turn-based artillery, not racing.
Hedgewars is just damn cute. It's immediately understandable, surprisingly deep, and just weird enough to stick in your head. It takes the artillery mayhem of Worms, replaces the soldiers with homicidal hedgehogs, and turns it into a polished free and open-source multiplayer game.
