Welcome to MCStacker for Minecraft 1.21.3. This website will help you generate many commands for Minecraft Java Edition. The syntax for commands containing items changed significantly in recent versions. Fortuanately, MCStacker can convert most of your 1.20.4 style commands and output them in the new format. Most of the specific options available for entities, items and blocks can be generated with this tool. MCStacker began in 2014 and many new features have been added regularly ever since. I continue to implement new functionality and keep it up-to-date to the latest version of Minecraft.
Development of this site relies on your ongoing support. You can help support me by purchasing the Installable Deluxe Edition of MCStacker. Or you could support me on Patreon. That also gets you the offline edition. Or if you want to, an occasional donation on Ko-fi is also appreciated.
There are key differences in the three flavors or MCStacker. Before purchasing, please make sure you're getting the edition which best meets your needs.
