McpeTool vs Snowstorm

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.

Snowstorm is a custom editor and generator for Minecraft Bedrock Edition particle files. Its web app is available at snowstorm.app, and a Visual Studio Code extension provides another way to edit particle files; that extension requires the name pattern *.particle.json. A Quick Setup tab offers preset particle motions and appearances to get a project started. Files can be added to Minecraft Bedrock resource packs and used in experiences. The project repository identifies JannisX11 as owner, lists a GPL-3.0 license, and says the web app can be hosted locally using a preferred local server. Snowstorm is free, with a listed free version at free. The supplied platform listings include Android, iOS, Linux, macOS, web, Windows, and extension. Snowstorm is also described as a decentralized microproxy network, with client and volunteer-peer uses for censorship circumvention. Microsoft Learn says it is provided by external contributors, not Mojang or Microsoft.
