What is Minecraft?

Minecraft is a popular sandbox survival game that is based on voxel blocks world. In Minecraft players can build anything from a simple home, gardens, castles, and camps.

Minecraft was originally designed back in 2009, as it gains popularity, many developers attempt their own free, open-source versions of it.

In this article, we will provide you with a quick list of open-source Minecraft alternatives for gamers, and developers.

1- Minetest

Minetest is our first pick, not just because it offers a solid experience similar to Minecraft, but because it has a rich content library (Content DB) which contains many user-generated mods, games, and texture patterns.

Minetest comes with its easy-to-use package manager which user can install and run mods and games. It also allows users to run different worlds, with custom mods.

Users can choose to host a server, or join an existing one without having to worry about complex setup or extensive instructions.

Developers on the other hand, can create custom mods, worlds, or even their own game using Lua scripting language, later on they can submit their creations to Minetest Content DB (Content Database).

Minetest also allows players to join dozens of servers, install mods, and games, environments in seconds. It is an ideal especially for kids and teens to explore and build their own structure.

Veloren works seamlessly on Windows, Linux, and macOS. Furthermore, it does not require heavy resources, and it can work on old machines as well

Although, it does not offer many customizations like Minetest, it is not suitable for children, (my son was terrified with a tiger attack).

However, it requires an account which you can create at https://veloren.net/, but keep in mind that you can reset your password through email.
