Sync Sign Notice
by BaicaiBear
Sync Sign Notice keeps signs in a Minecraft world showing the newest items from a configured database, so a single sign can act as a live news board.
What it does
Signs built from a chosen wood type pick up their text from a database connection that the mod opens when the world starts. Each sign is set up by writing a fixed format on its lines: a notice heading on line 1, the news item number on line 2, and custom text on line 3 if left blank in the database. The number counts from 1 for the newest item, up to the configured maxNewsCount, so the oldest entries are the last to appear.
The mod is a client-side only Fabric mod, so the server side needs nothing, and only players with the client installed see the synchronized notices. Files exist for 1.21 – 1.21.4 on Fabric, and the latest build is 1.0.0 for 1.21.4, released on 2025-06-29. The code is open source under the MIT License, and the project's wiki and issue tracker hold setup instructions and troubleshooting notes.
Key features
Database-driven sign text
Signs show news items pulled from a database, which updates the text without editing each sign by hand.
Format-based sign lines
Line 1 carries the notice heading, line 2 selects the news item by number, and line 3 holds custom text when the entry is left blank.
Configurable item count
The number of news items shown is set by maxNewsCount, so the sign cycles through as many entries as the configuration allows.
Automatic database connection
The configured database is connected when Minecraft starts, so the sign data refreshes without a manual step each session.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Who it’s for: Players who run a notice board in their own single-player world or on a client they control, and people who want signs that update from an external source. The mod does not run on servers, so it cannot push updates to players who do not have it installed.
How it compares
Clickable Signs is a server-side only Fabric mod, released under the MIT License, that makes signs interactive and is published for newer builds. NoticeExpress is also a Fabric mod under the Apache License 2.0, but the server needs it and clients may leave it out, with builds for 1.21.7 – 1.21.11. Sync Sign Notice is client-side only and works on 1.21 – 1.21.4, so it suits players who want the display on their own client.
