Build Undo is a lightweight quality-of-life Fabric mod for builders who sometimes place a block in the wrong spot and want a quick, fair way to fix it.
The mod tracks your own successful block placements and lets you undo or redo them with keybinds. It is designed to feel like a small building helper, not a cheat tool or WorldEdit replacement.
