Questions
 
FAQ
 
 
 
  Is it really 100% free?   
Yes. No trials, no premium tier, no ads, no sign-up. Build as many addons as you want.
 
  Which Minecraft version is supported?   
The exporter generates files for Minecraft Bedrock 1.20 – 1.21. Bedrock addons (.mcaddon) work on Windows, mobile, console and tablets.
 
  Do I need to install anything?   
Nothing. The builder runs entirely in your browser. The export is a single .mcaddon file you drop into Minecraft.
 
  How is this different from MCreator?   
MCreator requires a 1GB+ Java install and runs locally. We do the same job entirely in the browser, with no install and no limits.
 
  Can I share my addon with friends?   
Absolutely. Send them the .mcaddon file. They double-click it and it's installed in seconds.
