Piggy Build
by porkyoot
Piggy Build is a Fabric utility for Minecraft 1.21.1 that speeds up block placement and breaking in creative building.
What it does
Piggy Build offers a shape selector and block placement tools aimed at creative building. Directional placement locks a block's orientation to a chosen face, which suits logs, pillars and pistons that need a specific facing. Diagonal placement lets a builder lay blocks at an angle, and fast placement keeps placing blocks while the use key is held. Fast breaking removes blocks more quickly, but only in creative mode. Keys for these tools can be rebound from the controls screen.
The mod is client-side only, so only the client needs it and servers run without it. It is open source under the CC0 1.0 Universal license, with public source code and an issue tracker. Files target 1.21.1 for Fabric alone, with the latest build, 2.0.1, published on 2026-04-25. The mod was first published on 2025-12-07 and last updated on 2026-04-25. Settings are reachable through Mod Menu. The author describes the project as a personal one, with regular fixes planned.
Key features
Directional placement
Locks the placement direction to the block face the cursor is on, for aligned builds across a surface.
Diagonal placement
Places blocks diagonally, so angled sections can be built without rotating each block by hand.
Fast placement and breaking
Holding the use key places blocks in quick succession, and creative-mode breaking removes blocks faster.
Shape guides and overlays
Visual overlays show the shape a placement will fill before the blocks are set down.

Use cases
Who it’s for: Players who build in creative mode on Fabric 1.21.1 and want placement tools that go beyond the default. Single-player and multiplayer clients can run it alone, since no server installation is needed.
How it compares
BlockRotationLock is a Fabric client mod for 1.21.10, released under the CC0 1.0 Universal license and open source, so it covers a different version than Piggy Build. RedstonePlacement+ is a Fabric client mod for 1.21.11 under the MIT License and not open source. Modder's Piggy Bank targets Fabric and NeoForge for 1.21 – 1.21.1 under the MIT License and is open source, so it reaches NeoForge where Piggy Build does not.
