Luanti is the leading free, open-source alternative to Minecraft: a 150 MB voxel engine with hundreds of downloadable game modes that runs on low-end hardware and cannot be shut down. It is a platform rather than a finished game, so the default experience is sparse — install a game mode first. Minecraft remains more polished out of the box, but it costs money and has no free tier.
Luanti (formerly Minetest) is the free, open-source voxel option, and comparing it to Minecraft directly is slightly misleading — it is an engine with hundreds of games on it, not a single game. That distinction determines whether you will like it.
| Luanti | Minecraft | |
|---|---|---|
| Price | Free, open-source (LGPL) | Paid, no free tier beyond a browser demo |
| What it is | Engine plus a content browser of game modes | One finished, curated game |
| Out-of-box experience | Sparse — install a game mode first | Complete and polished immediately |
| Install size | ~150 MB | ~1 GB+ with assets |
| Hardware demands | Runs on very low-end machines and Raspberry Pi | Needs considerably more |
| World size | Effectively unlimited, larger vertical range | Large but bounded |
| Modding | Lua, first-class, in-game browser | Java, third-party toolchains needed |
| Multiplayer | Self-hosted servers, no account required | Official realms or third-party servers |
| Longevity | Open-source — cannot be shut down | Depends on Microsoft |
You want it free and permanent, you are running modest or old hardware, you enjoy configuring your own experience, or you want first-class Lua modding.
You want a finished, polished game with no setup, you care about the specific content and progression Mojang designed, or your friends already play it.
Commercial, published by Mojang. Not in the PlayBound catalog — it is not free.
Official siteLuanti stopped being a Minecraft alternative a long time ago—and that's exactly why we picked it. What began as a simple voxel experiment has evolved into an open platform where completely different games can live inside the same engine. The sheer amount of player-made content makes it feel less like one game and more like a tiny open-source game ecosystem.

Luanti is free and open-source under Open Source (LGPL-2.1). Minecraft is a commercial product and is not free, which is why it is not in the PlayBound catalog.
