Command Block Delay
Command Block Delay lets server owners set a delay on command blocks, so a command runs after a chosen wait instead of at once.
What it does
The mod adds delay command blocks that hold a command for a set time before it executes. A new box beneath the Command Console sets the input delay, and a button makes the execute run only on the first tick when repeating command blocks are used. The delay blocks are meant to behave exactly like their Bedrock Edition counterparts.
Installation needs Fabric. Only the server requires the mod, so players can join a server that runs it without installing anything, though the client may add it. Command Block Delay is published for Fabric alone, with a single build, 1.0.0, for 1.21.11. It is released under the MIT License and is not open source.
Key features
Delay command blocks
Delay command blocks hold a command for a set time before it executes, so timed sequences can be built without extra redstone.
Delay input box
A box beneath the Command Console sets the input delay that a command waits before it runs.
First-tick repeat option
A button makes a repeating command block execute only on its first tick, which controls when a repeat fires.
Powered after pulse
An option keeps a command block running after a pulsed power source such as redstone ends, so the delayed command still completes.

Use cases
Timed build sequences
A map maker can stage a build or effect so that each command fires after a fixed wait, without stacking many redstone clocks.
Adventure and event scripting
Server owners can space out events such as spawns or announcements by delaying their command blocks, without rewriting the commands.
Who it’s for: The mod suits server owners and map makers who script command blocks and want fixed waits between their commands. Players who only join a server gain nothing from installing it.
How it compares
BulbTickFix is a Fabric server-side mod for 1.21.11 under the MIT License and is not open source, so it only runs on the server. Command on Interval is a server-side Fabric mod for 1.21 – 1.21.1 under the Mozilla Public License 2.0 and is open source, so it covers an older version range. Placement Delay is a Fabric mod for 1.21 – 1.21.11 under All rights reserved, and it needs the client, with the server optional.

What the author says
This mod adds a delay to Command Blocks, exactly like in Bedrock Edition! It adds a new box beneath the Command Console to allow to input a delay to when the command runs. There is also a button to make it execute on the first tick, but only for Repeat Command Blocks.
