WhatBlock
Lightweight client-side HUD that shows the block you’re looking at: icon + localized name + registry ID. Auto-hides when you aren’t looking at a block.
⬇ Download on ModrinthWhatBlock — Know what you’re looking at
Tap into instant block info without the clutter. WhatBlock is a tiny HUD that pops in only when you aim at a block—showing [icon] Localized Name | registry:id—then politely disappears. It’s the “just enough info” tool you’ll actually keep installed.
Why players love it
Instant clarity. Icon + proper name + minecraft:id at a glance.
Stays out of your way. Auto-hides on sky/air and when any GUI is open.
Reads your language. Uses your current locale for names.
Featherweight. One small overlay, negligible overhead, no keybinds or setup.
Modpack friendly. Works with vanilla and most Forge mod blocks.
Perfect for builders, pack makers, content creators, and anyone who goes “wait, which block is that?”
What you see
A clean pill near the top of the screen:
Icon of the block (when available)
Localized block name
registry:id for quick searching or commands
