Minecraft Tools FAQ

Are the tools free?
›

Yes. Every tool is free, runs in your browser and needs no account or download.

Which version of Minecraft are they for?
›

They follow Java Edition 1.21 rules. Most of the maths (portal coordinates, circles, beacon and anvil costs) is the same on Bedrock; the Stronghold Finder needs the facing angle from the Java F3 screen.

Do the calculators work on phones?
›

Yes. All of them work on a phone or tablet, and the generators let you zoom and tick off blocks as you build.

Can I suggest a tool?
›

Yes please. Use the “Found a problem on this page?” link at the bottom of any page to tell us what you would like next.
