Client-side Minecraft Forge mod for 1.20.4 that provides real-time inspection and replay of outgoing serverbound packets. Uses a Mixin to hook into Minecraft's network layer, intercepting every packet sent from the client to the server before it is transmitted.
Captured packets are decoded and displayed in a custom in-game GUI built on Minecraft's native screen system. The overlay is toggled via the Insert key and lists all captured packets in a scrollable view. Selecting a packet populates a side panel with each field's name and current value.
Fields are editable, and the mod can reconstruct and resend a modified packet, supporting the full range of 1.20.4 serverbound game packets.
