McpeTool vs WorldPainter

McpeTool is a free, offline utility for reading and writing Minecraft Bedrock Edition world data. Its command-line interface and local HTTP API provide get, put, and delete operations. Database commands list, retrieve, write, and delete key/value pairs in a world’s LevelDB store. Level-data commands retrieve or replace level.dat contents using JSON, YAML, hex dump, base64, or binary formats. NBT data can be converted to JSON and YAML, and relevant commands accept or produce base64 and binary data. The API starts a local HTTP server and handles GET, PUT, and DELETE requests for database keys. The tool runs on Linux, macOS, and Windows and can be self-hosted or used through its API. It is MIT-licensed and intended as a basic access layer for people building more capable world editors. McpeTool cannot be used while Minecraft is running the world because LevelDB allows only one process at a time. The maker calls it a work in progress, says input validity is not currently checked, and advises backing up worlds before changes.

WorldPainter is a free map generator for Minecraft Java Edition, available on Windows, macOS, and Linux. It lets you sculpt terrain and paint materials and landscape details such as trees, snow, and ice, then export a generated world directly to your Minecraft saves directory. It is designed mainly for making maps; changing an existing map is limited to Import and Merge operations. You can use custom mod blocks, with fully qualified names for Minecraft 1.15 and later and numeric IDs for versions 1.12 and earlier. Custom object layers can load BO2, BO3, schematic, or NBT objects. WorldPainter cannot create Minecraft structures itself, but it can direct Minecraft to generate them during population. The software requires Java 17 or later. The download page provides SHA256 checksums for installer files, and the maker points users to its official subreddit for support. There is no proper user manual yet, though the maker links to documentation for controls, FAQs, plugins, and scripting. One stated limitation is that it cannot customize biomes while leaving Minecraft to generate all the land according to those biomes.
