Branding & Compatibility

Papyrus identifies itself as Papyrus by SushiMC at runtime while remaining API-compatible with Paper plugins.

Server brand

Property	Paper	Papyrus
Display name	Paper	Papyrus
Brand ID	papermc:paper	sushimc:papyrus
Maven group	io.papermc.paper	io.papermc.paper (unchanged)
Gradle modules	:paper-api, :paper-server	Same names; dirs are papyrus-*
Release jar	paper-*.jar	Papyrus-<mcVersion>.jar
CI / local jar	paperclip-*.jar	papyrus-paperclip-*.jar

Startup message:

Loading Papyrus <version> for Minecraft 26.1.2

ServerBuildInfo

Use Paper's ServerBuildInfo API instead of hard-coded brand checks:

import io.papermc.paper.ServerBuildInfo;

ServerBuildInfo info = ServerBuildInfo.buildInfo();

if (info.brandId().equals(ServerBuildInfo.BRAND_PAPYRUS_ID)) {
    // Papyrus-specific logic (sushimc:papyrus)
}

// Preferred for Paper-targeted plugins — works on Paper and Papyrus
if (info.isBrandCompatible(ServerBuildInfo.BRAND_PAPER_ID)) {
    // Paper-compatible server
}

Plugins that call isBrandCompatible("papermc:paper") are supported on Papyrus.

Update checker

Papyrus disables the PaperMC update checker by default (update-checker.enabled: false in new configs). Fork builds are distributed via GitHub Releases and CI.
