About this Mod

PlayerBatch 🤖

PlayerBatch is a lightweight Minecraft mod for Fabric + Carpet that lets you spawn, manage, and control large groups of fake players with a much cleaner command workflow.

Instead of dealing with messy repeated fake-player commands, PlayerBatch gives you batch spawning, selection tools, kits, presets, formations, and testing utilities for PvP practice, server testing, automation, technical setups, and large-scale scenes.

Frequently Asked Questions

PlayerBatch 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 PlayerBatch compatible with fabric?

PlayerBatch officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with PlayerBatch – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if PlayerBatch 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.
