About this Mod
This mod connects Minecraft directly to OBS Studio using the OBS WebSocket plugin, allowing the mod to automatically capture almost every kill using the Replay Buffer. The mod organizes all clips in player-specific folders and sorts them.


Kill detection works in two modes:
Packet Mode listens directly to Minecraft network packets to detect when a player dies, but it depends on the server sending complete data. If the damage source or attacker entity is missing, the mod will not function
Chat Mode watches the Minecraft chat for specific kill messages sent by the server.
Dependencies
- Cloth Config API
- Fabric api

KillClipper server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.
Is KillClipper compatible with fabric?
KillClipper officially supports fabric for Minecraft 1.21.11, 1.21.10, 1.21.9. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with KillClipper – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if KillClipper consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
