MCreator is now open source

After months of work on all the things needed for this to happen, MCreator is finally open source. We hope this will make this project even better than ever. Read on!

I hope that by open-sourcing, more developers will help me with development and thus move things faster. Based on the survey I put out a while ago, this is the case, so I can't wait to see how things will go!

The new repository is located on the MCreator GitHub organization page under the following URL:

Make sure to star the project on GitHub ;)


If you are interested in helping with MCreator development, you are welcome to support this project by opening pull requests. Even if you do not code, you can help by contributing translations, in-app tips, or by donating. Read more on contribution on

A new forum section was opened for discussions on features and changes for the developers. This way we can coordinate new features so we can keep things streamlined and prevent two people from doing the same thing. The other place for coordinations will be the issues page on GitHub and pull request drafts.

Due to a lot of work still waiting for me to complete the open-sourcing process (especially changes on the website), I might not be able to reply instantly to early pull requests and issues, but it should get better after the initial changes.

Issue tracker

The issue tracker will be moved from MCreator's website to GitHub. The current tracker will remain archived, but will soon close for any new tickets. Existing tickets will be migrated to GitHub.

Some other changes on the website to reflect open-sourcing will happen in the upcoming days. Issue numbering will restart from #1 after the move too, existing numbers will not be affected.

Big thanks to our trial moderator Shocking Artist who designed the issue templates for the new GitHub issue tracker.


Some of the code is documented, but most of it not yet. I will try to improve this as much as possible relative to the time I will have, of course. To help you get started, I will post pages in GitHub Wiki occasionally with some guides on where to find things in the code and how the MCreator is structured and how things work.


Releases will remain on the website. Anyone can build their own variant anytime, but officially verified binaries supported by Pylo and maintained will be downloadable on this website as it always was.

Please let us know what you think about this major change in the comments. Also, leave any suggestions and concerns here so we can discuss it. Also, who will be the first contributor, we are waiting? ;)

To be serious a few seconds, it will help a lot the software for a lot of reasons. The community will be bigger, the software will be bigger. This thing will definitively change MCreator forever. now, nobody can say that MCreator or its code is bad because they are able to change it for a better thing. It was a lot of work, but it will be a good help for it. Continue your awesome work Klemen (and Matej too :))!

For feature request will this be opened as issues or is there going to be some kind of alternate way to submit feature requests to you still, or are you just dropping support for this all together. Because I feel like this was one of the reasons why the community has come so close is that we can ask for features and the devs listen to the requests unlike many developers out there.

Now I just need to practice 1.16 modding and datapacks then I will try to add them.

Donate to MCreator

By donating to developers you can speed up development, as with more resources, we can dedicate more time to MCreator. It is a free project made by developers working on it in their free time.
