FreeMinecraftMods decision guide
This mod is most relevant to players looking for Map and Information, Server Utility on NeoForge, Fabric, Forge. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.
The source record was updated on Jun 26, 2026, which is a recent freshness signal. A recent date does not guarantee support for every loader or Minecraft version, so still inspect the current file list.
What to verify before choosing a file
- Confirm that the file is published by the credited creator on the linked official source.
- Match the Minecraft version exactly instead of relying only on a broad category label.
- Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
- Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
- Back up worlds and configuration files before testing the project in a long-term save or public server.
