StringDuper
StringDuper is a lightweight Minecraft plugin that enables controlled string duplication through a smart, tick-based farm system. No client installation required — works for all players including Bedrock via Geyser.
Features

• Tripwire-based string farm — uses only vanilla blocks, no new items or crafting recipes
• Player proximity check — farm automatically pauses if no player is within 64 blocks, preventing entity spam when you walk away
• Performance optimized — structural validation is cached and throttled; water checks are lightweight per-tick reads
• Farm cap — hard limit of 8 concurrent farms to prevent server lag or griefing
• Multi-world safe — hooks are tracked per world, no cross-world false positives
• Bedrock support — fully compatible with Geyser, Bedrock players can build and use the farm

Requirements

• Paper or Spigot 1.13+
• Java 17+

Notes

• Server-side only — no client mod needed, works for all players out of the box
• Compatible with most plugins that do not override tripwire block behavior
