Stamp
Stamp is a client-side Fabric utility that repeats sign text on signs placed after the first one, for players who write the same lines often.
What it does
A player writes text on a sign by hand and presses Done. The mod keeps those lines in a cache. The next sign that opens is pre-filled with the cached lines, and the mod submits it on its own after a 500 millisecond wait. The delay is meant to keep bursts of sign packets below rate limits that some high-frequency server filters apply, which the author names as the reason for the wait on anarchy servers such as 2B2T.
Chat commands control the mod. Typing .stamp on enables it and readies the cache, .stamp off disables it and clears the active cache, and a help message is printed locally. Re-enabling the mod starts with an empty cache. Stamp intercepts these commands before they reach the server, so nothing is sent to the server for them. The mod is open source under the MIT License and is published for Fabric only, in 11 release versions covering 1.21.1 – 1.21.11.
Key features
Cached sign text
Lines written and confirmed on a sign are stored, then applied to the next sign the player places.
Automatic submission
A pre-filled sign is submitted after a fixed 500 millisecond cooldown, so the player does not confirm each one.
Chat command switch
The .stamp on and .stamp off commands turn the behavior on or off, and turning it off clears the cache.
Local help output
Typing the command help prints usage instructions in the local chat only.

Use cases
Repeated sign text
A player placing many signs with the same lines, such as shop labels or marker text, can fill them with one written sign.
Servers with packet filters
The cooldown spaces out submissions, which is the stated purpose on servers that drop rapid sign packets.
Who it’s for: Players who place many identical signs on servers or single-player worlds. Server owners do not need to install anything, because the mod runs only on the client.
How it compares
EGLUTierList is a Fabric client mod for 1.21 – 1.21.11 under All rights reserved, so its code is not open source. Sync Sign Notice is also client-side only and open source under the MIT License, but it is published for 1.21 – 1.21.4 and does not repeat sign text. Signit- A mod to sign anything! is a server-side Fabric mod for 1.21.1 only, so it needs installing on the server instead of the client.

A minimal, client-side Fabric utility mod for Minecraft 1.21.1 designed for automated sign text repetition on anarchy servers like 2B2T.
