Pick the current Fabric 26.3 build or the older 26.2 one. Both are a single file with nothing extra to install.
Current release — Fabric 26.3. The whole overlay is here for Minecraft 26.3: room revealing, secret counts, a live score readout, star mob finding, wither door highlighting and run logs. Installing it works the same as ever — one JAR into your mods folder, then /fmap in game.
Fabric 26.2. The older build, still offered for anyone not on 26.3 yet.
Download the 26.2 BuildFirst get Fabric Loader onto your Minecraft 26.3 install, or 26.2 if you are using the classic build. The official Fabric site has the installer.
Use the download button above to save the mod's JAR file.
Move the JAR into your .minecraft/mods folder. On Windows, Win+R then %appdata%\.minecraft\mods takes you straight there.
Boot the game on the Fabric 26.3 profile, or 26.2 for the classic build. The mod loads on its own; type /fmap in game to adjust it.
