Minecraft and open source?


There's no denying that Minecraft is a favorite game for millions. And being written in Java enables it to run on a variety of platforms, including Linux. With a huge modding community, there are countless Minecraft tinkerers out there who would love to be able to get under the hood and play around with the source code themselves. Unfortunately, the source is not available to the general public.


But there's good news. Minecraft's popularity has led to many attempts to recreate the game, and others in a similar vein, as open source software. Interested in a free Minecraft alternative? Here's a quick look at some clones and derivatives out there that you really ought to check out.


These projects are in widely varying levels of completion and serve a number of different goals. Some seek to duplicate the Minecraft experience completely, or to at least provide a very similar experience. Others are taking the voxel-based gaming concept in entirely new directions, and still others are really more of a framework to help you build your own game or creation.


The first game on our list is Minetest. Minetest is perhaps the most complete alternative to Minecraft, which is billed as a "near-infinite-world block sandbox game and a game engine." It supports multiplayer games and subgames, and features a number of terrain generators and different default biomes. It also features a very user-friendly API for creating mods in Lua.

Minetest is open source under the LGPL, and is written primarily in C++ so it's fairly fast compared to some others written in scripting languages. Minetest runs on Windows, OS X, Linux, Android, FreeBSD, and possibly other operating systems as well. Check out the source code on GitHub.

Terasology might win the award for the most beautiful rendering engine in the pack; its shadows are both ominous and spectacular. What started out as an experiment in procedural terrain generation has turned into a full-featured game, complete with multiplayer and a number of add-on modules installed by default to let you try out different gameplay mechanics.

Terasology is written in Java and made available under an Apache 2.0 license. Because of its Java-based system, it ought to run on just about any platform with sufficient power, so long as you have a Java 8 virtual machine installed.

The odd one out in this list is Voxel.js; unlike the others, it's not a game at all and doesn't claim to be. Instead, Voxel.js is a JavaScript library enabling you to build your own Minecraft-style games, renderings, or other interactive widgets in JavaScript and HTML, enabling easy embedding on any webpage with no special plugins needed for any browser that supports WebGL.

Voxel.js is put together as a number of related projects, meaning you can use as much or as little of the code as you wish when you craft your perfect game. The main library, voxel-engine, is a fairly basic engine for rendering boxy scenes, but there are over 200 additional add-onsavailable. Check out the gallery for some ideas of what others have built with the engine. The main engine is released under a BSD-style license; other add-ons may be licensed differently, so it's worth checking before you make assumptions.

TrueCraft is written to be very close to the original game. It is described as a Minecraft "implementation," as opposed to a clone, and is compatible with official Minecraft server releases. The author of TrueCraft seeks to implement beta version 1.7.3 of the original game, a time in Minecraft's development he deems "nearly perfect." A snapshot intentionally frozen in time, TrueCraft seeks feature-parity with Minecraft.

Because it is so close to the original, TrueCraft has taken great pains to avoid copyright issues by allowing code only from developers who have not decompiled or otherwise had access to the original game's source code, though those who have are welcome to contribute in other ways. TrueCraft is written in C# and is open source under an MIT license.

Craft is another open source voxel engine in the style of Minecraft. Development seems to have slowed or stopped, but there are over 200 forks, many (such as the school project not2bad-craft) with major improvements. Craft's simplicity may appeal to you if you're interested in building a game similar to Minecraft but aren't sure where to start: the game engine resides in just a few thousand lines of C code and uses OpenGL for rendering. It uses simple algorithms for terrain generation and other tasks, and everything is stored in an SQLite3 database. There's also a Python-based multiplayer server which is worth giving a try.

Craft is made available under an MIT license.

Other great options

Some other notable mentions you should try:

  • Freeminer is another sandbox game inspired by Minecraft and based on Minetest. As a fork, the authors seek to "make the game fun while trading off some bits of perfectionism." It has installers for Linux, Windows, and Android.
  • ClassiCube is a Minecraft Classic clone written in C#. It is open source under the OpenTK license, and installs on Linux, BSD, Solaris, Windows, Mac OS, and in a browser.

And there you have it. This list is far from comprehensive; there are many other options out there just waiting for you to explore, and as time goes on we'll undoubtedly see more choices emerge as enthusiasts fork these games or strike out on their own. Which one is your favorite, and which one did we leave off that you wish we had covered?

Interesting article Jason. There are a number of schools and libraries that are promoting Minecraft in their classrooms and maker spaces.

What a great addition, thanks for the suggestion!

Just wanted to give folks a heads up, there's a great Reddit thread going on about this topic if anyone wants to chime in over there. And welcome to our visitors who came over from the /r/linuxgames subreddit, feel free to comment in here as well!

This is great to know. I am hopeful that Microsoft doesn't mess up Minecraft too much but already a system that ran Minecraft just fine in Windows 7, could not run the base Minecraft in Windows 10 except their Windows 10 beta, which is based on the Mobile version.

Puts a crimp in any plans of playing on the same worlds between PC-based and Mobile-based. Not to mention, how long will it continue to be free (with a Mojang account)?

Interesting , how the game just keeps "morphing" game to game ... Come to think of it , LINUX became the powerhouse OS it is today in much the same fashion ...

Awesome article and many great choice. Most of them are yet to try for me but for the ones looking for some addition Jet Miner(http://www.minecraft-free-games.com/jet-miner) is great option.

Honestly, I think Minecraft (the original game) will always prevail, its the brand that is so valuable. Community hosted servers like https://www.dancraft.net/server/skyblock are also a great way Minecraft keeps fresh new content on their game without updating. Their most recent update (1.12.2 for PC), was just bug fixes and that was months ago

Thanks for sharing these great choices with us.
However, from my opinion.. I think Minecraft is the best.

Terasology is actually developed the way that it even has support for minecraft mods porting. It gives it lot of power as OpenSource game/platform.

Interesting Article, Minecraft has lots of alternatives. But still Minecraft is the best option according to me.

I've NEVER tried minecraft, but I tried Minetest , it's very good & enjoying.

Minecraft this is a never-ending topic ! Love playing Minecraft

Pretty sure you can just decompile it with MCP and then mess with it.

Can you play on a multiplayer server

I love minecraft, are there any RPG + voxel combo games?

I didn't know Terasology - it's truly beautiful!

Interesting article Jason. There are a number of ways people promoting Minecraft

Intresting Article

I have not played Minecraft yet. I want to play this game on console. I think that Minecraft team should work on other platforms.

It's time to build a better boss monster. No longer will you have to endure your players poking at your monsters' unearthedarcana
ankles until their hit points are whittled away, and the creature dies from a fatal blow to its big toe. Instead, your heroes can search a near-invincible foe for a weakness, try to exploit it, and fight hard to keep striking the monster where it hurts as it tries to protect its vulnerability. This house rule is great for gaming groups that want a more dynamic and thoughtful D&D combat experience—perhaps your group has very few combat encounters and you want them to be meaningful, or perhaps your game has lots of battles and you want your boss encounters to stand out from the trash mobs.

Because of the prevalence of weak point mechanics in video games like The Legend of Zelda, Shadow of the Colossus, and literally hundreds of other examples, this house rule may make your D&D game feel more like a game than a simulation of fantasy life. This doesn’t have to be the case: fantasy and mythology are flush with stories of legendary warriors and monsters with fatal physical flaws. Consider Achilles and his famous heel from The Iliad, the heavily armored Imperial walkers that could only be defeated by ensnaring their legs in The Empire Strikes Back, and the mighty dragon Smaug’s only vulnerability in The Hobbit.

Before using this house rule in your game, consider telling your players outright that your boss monsters will have a weak point that they can seek out to make defeating it easier.


Really intersting game I used to play back in 2019 but for now PUBG is best

its a really interesting game...

Minecraft has been a go-to game of mine for years and I look forward to trying out these open-source alternatives as well. They seem really amazing.

I'm a fan of open source games.

I exactly needed this , cuz i have recently shifted from win 10 to ubuntu .
I was not a hardcore minecraft gamer , but i played then.

Thanks Homie..

Thanks for giving great kind of information. So useful and practical for me. Thanks for your excellent blog, nice work keep it up thanks for sharing the knowledge GHD SPORTS

good article

Really interesting article

the best game so far at least for me ...

i don’t play and i still looooooooooove it

thanks, this is the list i was looking for

love but not played


Nice to see Terasology getting some publicity. I still can't believe that everyone prefers Minecraft when the aesthetics are so much better on Terasology.

Thanks for sharing, this is awesome. Would love to see more of these. <a href="https://gbmod.net/download-gbwhatsapp-apk/">GBwhatsapp APK</a> is the best app right now?

I would suggest viva tv for this kind of entertainment. Anyway thanks for bringing it up!


Best game for me
