Packet Spy

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): it stopped at org.java_websocket.server.WebSocketServer, a class from a jar nested inside the mod; Kiln does not unpack nested jars yet.

What it needs from Kiln

Mixin
net.fabricmc.fabric.api.client.event.lifecycle.v1.ClientLifecycleEvents
net.fabricmc.fabric.api.client.event.lifecycle.v1.ClientLifecycleEvents.ClientStopping
net.minecraft.network.protocol.Packet
net.minecraft.network.protocol.PacketType
net.minecraft.network.protocol.game.ServerboundMovePlayerPacket

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)

In the author's words

A client-side Fabric mod that lets you inspect Minecraft network packets live through a simple web interface.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file PacketSpy-2.4+mc26.3.jar. The scan reads the mod's classes; it does not run them.
