What Structra is

Structra is a free server plugin for Paper and Purpur that loads and saves schematics asynchronously over time. Its standalone block queue processes changes in batches, which the project describes as a way to help prevent server lag. Structra is not a WorldEdit addon. Commands let you use a wand to set two positions, save the selected region under a name, paste a saved structure, paste from history, and delete a saved structure. An optional batch-size setting controls how many blocks are handled per period; the default is 50. Developers can also use the plugin’s API. The project lists Paper 1.17 or newer and Java 16 or higher, with no dependencies required. Installation involves downloading a release, placing its plugin file in the server’s plugins folder, and restarting the server. Structra is licensed under GPL-3.0, and its project directs support questions to Discord servers. It is distributed as a server plugin with a free plan.
