Its README acknowledges JUCE, Google Material Design Icons, colormap-shaders, je2be-core, libminecraft-file, and Android SDK sources, but does not describe third-party service integrations. Release tags are marked as signed with the committer’s verified signature. The project pages reviewed do not state a support policy or contact. The repository’s Security and quality section provides no security or compliance details in the project description.

Prismarine Viewer is a free, web-based viewer for Minecraft servers and bots, available through API, self-hosted, and web use. Mineflayer mode serves a page showing a bot’s surroundings in first or third person and provides drawing functions; lines and displayed primitives can be replaced or erased by ID. Standalone mode visualizes a world without a bot, while headless mode renders a bot’s view for streaming to a file or over TCP. The project lists Minecraft support from 1.8.8 through 1.21.4; other versions in the same major use textures and models from the closest supported version. Online-mode servers can show wide or slim skins and capes when skin data is sent. Examples connect Mineflayer with proxies, Electron, Python, and WebSocket proxies, and export world areas as screenshots or 3D models. Server maps, live updates, and a 3D map view are supported. Install with `npm install prismarine-viewer`; the repository uses the MIT license. Mineflayer and standalone default to six chunks and port 3000.
