Jail Logic – Unofficial Update
by Abdo9616
Jail Logic – Unofficial Update is a server-side Fabric mod that lets staff imprison players in a virtual prison, blocking their interactions with the world until release.
What it does
An imprisoned player cannot use blocks, interact with entities, or empty and fill buckets with lava or water. Staff choose how long each jailing lasts, and the player is released automatically when that time runs out, or an admin can release them by hand. Each jailing records a reason, and when none is given it is shown as Unknown reason. Imprisoned players can check how much time remains, and staff can see every jailed player with their remaining time and reason through the jail list.
This is an unofficial community-maintained fork of the original Jail Logic mod, kept working on later Minecraft releases and adding a few optional refinements. The original project appears inactive, and its author is no longer releasing updates. The mod requires Fabric API and can optionally integrate with BanHammer. The fork is redistributed under the MIT License, and the original source code is released under CC0. Offline players can be released by name or UUID, and their jail status is cleared immediately while the saved state is restored on their next join. Issues with the fork should be reported to this project, not to the original developer.
Key features
Temporary imprisonment
Staff jail a player for a chosen span of time, during which the player cannot use blocks, entities or items such as lava and water buckets.
Automatic and manual release
A player is released when the set time ends, or an admin can release them early by hand.
Imprisonment reasons
A reason can be attached to each jailing, and omitted reasons default to Unknown reason.
Remaining time command
Imprisoned players can check how long remains until they are released.
BanHammer-style messages
Jail messages use player names in red, staff names in gold, and reasons and durations in yellow, with announcements that include the reason and duration.

BanHammer is server-side for Fabric and Quilt across 1.16.5 – 26.3 under the GNU Lesser General Public License v3.0 only, and it is the mod this fork can optionally integrate with.
