Silly's Bedrock Breaker
by sillyygoober
Silly's Bedrock Breaker lets a piston break bedrock, a block normally unbreakable in survival, by replacing the destroyed piston on the same tick.
What it does
When a piston pushes against bedrock, the mod breaks that bedrock block. The piston it was pointing at is then replaced by a headless piston, which updates redstone in the same tick so the circuit keeps working. Pistons can be broken from any direction, and the mod works from the top base of a piston as well.
The mod takes pistons from the player's inventory automatically, so they do not have to be held in the offhand. It is a client-side only mod: only the client needs Fabric API and this mod, and the server does not have to run it. It is distributed under CC0 1.0 Universal and is not open source. Files are published for Fabric alone, for 1.21.11 only, with version 1.0.1 for 1.21.11 as the latest file, dated 2026-09-15.
Key features
Bedrock breaking
Pistons break bedrock, which players cannot otherwise remove in survival, opening paths through bedrock layers.
Same-tick piston replacement
A destroyed piston is replaced by a headless piston on the same tick, so redstone updates without a gap.
Inventory piston swap
Pistons are swapped in from the inventory automatically, so no piston needs to be held in the offhand.
Trapdoor crawl setup
A trapdoor and piston setup can be used to crawl through a passage that the mod opens in the bedrock.

Use cases
Bedrock bypass on multiplayer servers
Players on large servers can open routes through bedrock without server-side changes, since the mod runs entirely on the client.
Who it’s for: Players who build piston contraptions in survival and want to break bedrock with redstone rather than with creative mode or commands.
