Double Doors Server

Double Doors Server

A Bukkit/Spigot plugin that opens mirrored double doors together, with low-latency syncing and optional compatibility handling for common server stacks.

Documentation

For detailed documentation, see the documentation.

Features

• Same-tick partner door sync
• Strict mirrored pair matching for doors:
  • same door type
  • same facing direction
  • opposite hinge
  • side-by-side only
• Optional recursive opening support for non-door openables (fence gates/trapdoors)
• Per-player toggle: /doubledoors toggle
• LuckPerms-friendly permission nodes
• GriefPrevention compatibility check for linked-door claim access
• Duplicate interaction debounce (helps packet duplication patterns seen with some Bedrock/Geyser flows)
• Translation support via JSON language files (built-in + custom)

Official sources

• GitHub
• Modrinth
• Hangar

Compatibility

• Supports Minecraft Java Edition 1.21.x, 26.1.x, 26.2.x, and 26.3.x.
• Java 25+ Runtime

Geyser / Floodgate

• Plugin declares soft-depends on Geyser-Spigot and floodgate.
• A short duplicate-interaction debounce window is used to avoid rapid duplicate toggles on the same block.

LuckPerms

• Works through standard Bukkit permissions, so LuckPerms applies automatically.
• Use doubledoors.use to allow/deny linked opening behavior.

GriefPrevention

• Plugin declares a soft-depend on GriefPrevention.
• When present, linked-door interaction is checked against claim build permission before toggling the partner door.

Platform Artifacts

• Use doubledoors-paper-<version>.jar on Paper, Purpur, or Folia. Paper downloads its SQL libraries when the plugin starts.
• Use doubledoors-bukkit-<version>.jar on Bukkit or Spigot. It includes all runtime libraries.

Proxy Setup (Multi-Server)

DoubleDoors includes an optional Velocity proxy plugin for Geyser/Floodgate environments with multiple backend servers.

Proxy Features

• Shared SQL heartbeat/presence tracking across multiple proxies
• Automatic detection of Geyser/Floodgate clients
• Support for SQLite and MySQL databases
• Connection pooling via HikariCP for efficient SQL resource usage
