Developing your own Hytale plugin: the server basics

Reviewed October 26, 2026 1 min read

If you write plugins, the official manual gives you two things: a Maven repository with the server jar, and advice on crash reporting during development.

From the official manual

  • The server jar is published to Maven: release at https://maven.hytale.com/release and pre-release at https://maven.hytale.com/pre-release, as com.hypixel.hytale:Server. Jars are provided for the last five releases.
  • Disable Sentry crash reporting (--disable-sentry) during active plugin development, so your development errors aren't submitted.
  • Packet definitions and the protocol structure are available inside HytaleServer.jar, under com.hypixel.hytale.protocol.packets.
Develop on a copy

Test plugins on a separate server or a copy of your world, never on the one your players are using.
