Limitless Command
Limitless Command lifts the vanilla 32,768-character cap on Command Block commands, so long fill and clone operations can be entered without errors.
What it does
On Forge, the mod lifts the Command Block character ceiling from 32,768 up to 2,000,000 characters. Large fill and clone operations that would otherwise fail with an error can run once the limit is lifted.
The mod works automatically once installed and needs no configuration. Because it alters networking packets and GUI screens, the mod has to be installed on both the client and the server. Filling hundreds of thousands of blocks in one command can still cause a temporary server lag or TPS drop, depending on the CPU.
Limitless Command is released under the MIT License and is not open source. Files are published for Forge only, for Minecraft 1.20.1, with 1.0.0 as the latest file from 2026-08-06.
Key features

Use cases
Building large areas
Players who fill big regions with one fill command can enter the full command without splitting it into several pieces.
Server build projects
Server owners running construction projects on a shared world can issue long commands that vanilla would reject.
Who it’s for: Players and server owners who use Command Blocks for large builds on Forge 1.20.1 and need commands longer than the vanilla limit.
How it compares
Easy fill is a server-side only Forge mod for 1.20.1 under the MIT License and is not open source, so only the server needs it. /fill Command Unlimited is a client and server Forge mod for 1.20.1 under the MIT License and is not open source, so it must be installed on both sides like Limitless Command.
