ExpireNoMore
by TejasIsCool
Players whose usercache.json entries expire too soon can use ExpireNoMore, a Fabric mod that pushes those expiry dates further into the future on a Minecraft server.
What it does
On startup, the server reads its usercache.json file, which maps usernames to UUIDs and stores an expiry date for each entry. ExpireNoMore checks each entry and, when the date is less than 50 years away, moves it forward by another 100 years. Entries that already lie further out are left alone.
The mod was written because player statistics are saved under each player's UUID, while the server displays names from the cache. When a name dropped out of the cache, stats could not be shown with it. Running the mod once, the first time it starts, is enough to extend the existing expiry dates, and the server can then run without it.
ExpireNoMore runs on the server alone, so players join without installing anything. It is built for Fabric and needs Fabric Loader above 0.15.1 and Java 8 or newer. Its latest file, 1.2.0, targets 1.21.11 and was published on 2026-01-28.
Key features
Expiry date extension
Each usercache.json entry whose expiry lies less than 50 years away is pushed forward by 100 years.
Runs once at startup
The change is applied when the server starts, so no ongoing process runs during play.
Stats display fix
Keeping names in the cache lets player statistics show the usernames of members who have not logged in recently.
Offline mode support
Offline-mode servers store names and UUIDs in the same file, so the same expiry extension applies there.

Use cases
Long-term server archives
Servers that keep worlds for years and track statistics for members who return rarely.
Recovering missing names
Owners whose stats pages show raw UUIDs for players who dropped out of the cache.
Who it’s for: Server owners running Fabric who want cached usernames to stay available for much longer, especially on servers that display player statistics.
How it compares
Online UUID Fix is a server-side only mod for 1.21.11 under the GNU General Public License v3.0 only, and it is open source. It addresses UUID handling rather than cache expiry. Cosmorph is a client-side only Fabric mod for 1.21.10 – 1.21.11 under the CC0 1.0 Universal license, so it does not run on a server.
