Stax

Stop typing long commands by hand. Stax is an in-game command builder: press K, fill in the fields, watch the command build itself with live syntax colors, then copy it or run it with one click.

✨ What's new in 1.2

• 🧩 Now on 1.21.11, 26.1, 26.2 and 26.3
• ⭐ Favorites: star a command and keep it forever.
• 🎯 Selector builder: click @ to build @e[type=...,distance=..10,limit=1] without typos.
• 📍 Coordinates button: fill in the block you're looking at (or your position) in one click.
• ▣ Command block button: get a command block already loaded with your command.
• 🎨 New pixel-art icon.

What came in 1.1

• 🐎 Passenger trees, MCStacker style: any entity can carry several riders, and every rider can carry its own. Build stacks visually in a tree, add/duplicate/reorder/delete riders, and edit each one with its own properties.
• 🎨 Redesigned UI: card layout, color-highlighted command preview over three lines, scrollable command list.
• 🕘 History: the last 50 commands you copied or ran, one click to load them back.
• ⌨️ Shortcuts: Ctrl+Enter executes, Ctrl+Shift+C copies.
• 🏷️ More entity properties: custom name, tags, No AI, never despawn, plus armor stand options (invisible, small, marker, arms, base plate).

Features

• Visual editor: every command is split into clear fields instead of one long line.
• Registry pickers: search items, blocks, entities, effects, particles and sounds instead of remembering IDs.
• Passenger editor: tree of riders with presets (armor stand, text/item/block display, falling block, item). Existing Passengers data is loaded back, and unknown NBT is preserved.
• Custom names & lore: style text with colors and formatting, no JSON by hand.
• Live preview with a 256-character counter, so you know when you need a command block.
• Import: paste an existing command and keep editing it.
• Copy or execute instantly.
