Welcome to the browser for Minecraft: Java Edition client- and server-side mappings!

You can move through this site by following links to specific versions/packages/classes/... or use the nifty search field in the top right corner (appears when in a versioned page!).

It is possible that there are errors in mappings displayed here, but we've tried to make them as close as possible to the runtime naming.
If you run into such an error, please report it at the issue tracker!
