Luanti review

Luanti, which used to be called Minetest, is the most open choice on this list. Its FAQ answers the price question in one word: nothing. The project describes itself as a free and open-source voxel game engine with its own content platform, and the home page lists maps of 62,000 blocks in each direction, solo, local and online multiplayer, texture packs and several map generators. Instead of one fixed game, you pick from many games and mods in the client, and ContentDB holds over 3,200 open source mods. Builders who want to go further can use the Lua API to make mods or whole voxel games without writing their own rendering or networking. Version 5.18.0 shipped on October 29, 2026, for Windows, macOS, Linux, BSDs and Android. It ranks below Roblox and Fortnite because there is no iPhone or iPad version and first-time setup takes a few more steps. For anyone who wants block building with no store at all, it is the best value here.
