What SchemFlow is

SchemFlow is a free, open-source plugin for managing Minecraft server schematics with local or cloud storage. It connects to MinIO, AWS S3, and compatible services such as Cloudflare R2, DigitalOcean Spaces, and Wasabi. Downloaded schematics can also be pasted offline using the `local:name` syntax. The plugin works with WorldEdit and FastAsyncWorldEdit, supports `.schm` and `.schematic` files, and includes flags for entities, air blocks, and biome preservation. Server teams can automate tasks with Skript syntax or an asynchronous developer API for provisioning and disposing of worlds, inspecting schematics, and saving selections as maps. Safety controls include trash and restore, undo and redo integration, and confirmation prompts for destructive actions. The README reports cached tab completion at 50 ms compared with 800 ms before caching, plus a 90% reduction in S3 calls. SchemFlow is released under the Apache-2.0 License. It requires Minecraft 1.21–1.21.11, Java 21+, and WorldEdit 7.2.18+ or FastAsyncWorldEdit; Paper or Purpur is recommended. The project lists build, creative, competition, and survival servers as intended environments.
