Platform

dev.architectury.platform.Platform

A static utility for asking about the running game: which loader, which environment, where the game's folders are, and what mods are loaded.

Loader detection

if (Platform.isFabric()) {
    // Fabric-specific path
} else if (Platform.isNeoForge()) {
    // NeoForge-specific path
}

You rarely need this in common code - the whole point of Architectury is to avoid loader checks - but it's there when a behavior genuinely differs.

Game folders

All return an absolute, normalized java.nio.file.Path:

Method	Folder
getGameFolder()	The Minecraft instance root.
getConfigFolder()	The config folder.
getModsFolder()	The mods folder.

Path config = Platform.getConfigFolder().resolve("mymod.json");

Environment

Env env = Platform.getEnvironment();   // Env.CLIENT or Env.SERVER
boolean dev = Platform.isDevelopmentEnvironment();
String mcVersion = Platform.getMinecraftVersion();

getEnvironment() returns Architectury's Env; getEnv() returns the platform's EnvType if you need it. To run code only on one side, use EnvExecutor.

Querying mods

if (Platform.isModLoaded("jei")) {
    // integrate with JEI
}

Mod mod = Platform.getMod("mymod");                 // throws if absent
Optional<Mod> maybe = Platform.getOptionalMod("jei"); // empty if absent

Collection<Mod> all = Platform.getMods();
Collection<String> ids = Platform.getModIds();

getMod / getOptionalMod return a Mod container with the mod's metadata.

Accessing the server

dev.architectury.utils.GameInstance

MinecraftServer server = GameInstance.getServer();

Returns the currently running MinecraftServer, or null when none is running (for example, on the title screen of a client). This is the cross-platform way to reach the server from anywhere.
