Auto Fastbridge

Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.

by AgentChicken · on CurseForge

The Auto Fastbridge mod automatically makes you sneak when standing at the edge of a block, helping you bridge faster and safer.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

When you stand on the edge of a block, the mod automatically enables sneak mode to prevent falling — perfect for fast bridging. You no longer need to press the sneak key yourself. The mod can be toggled easily by pressing the G key, keeping your gameplay smooth and your fingers relaxed — ideal for PvP or quick building sessions!
