# <img src="icons/nbtworkbench.png" width=48> NBT Workbench

### [Downloads & Releases here!](https://github.com/RealRTTV/nbtworkbench/releases)

NBT Workbench is an [NBT](https://minecraft.wiki/w/NBT_format) editing application,
the successor to [NBT Studio](https://github.com/tryashtar/nbt-studio),
which is in turn the successor to [NBTExplorer](https://github.com/jaquadro/NBTExplorer).
NBT Workbench is written completely from scratch in [Rust](https://www.rust-lang.org/) and designed to be as performant and efficient as possible.\
<small>Please note that this is my first "big" project, so bug reporting really helps me out here!</small>
