MInetest is very very good game.

Minetest is an amazing open-source game with built-in modding support
Great performance and very easy to use in a local network.
It is a better clone than the others. It is kinda bad, but it has enough blocks to be kinda good. The shading looks meh
actively developed and by far the most popular open-source minecraft alternative.
Very similar but better moddability and code performance. Thus in some respects better than Minecraft.

MineClone 2 vs Minecraft opinions
is buggy and the world is too small
Experience very similar. Many Minecraft features are there.
An alternative to the Java web game "Minecraft Classic" that was listed on the official Minecraft site but taken down in 2016-2017.
ClassiCube vs Minecraft opinions
Based on the style of classic Minecraft, this game is really neat, has a lot of potential, is fun, and hits close to home for those who have played classic Minecraft. I definitely recommend ClassiCube, even as it's own game overall.
It has fun servers, and I found it when I was searching for a similar game for Chromebook.
Free "Creative Mode" (though outdated).
