What Prismarine Viewer is

Prismarine Viewer is a free web-based viewer for Minecraft servers and bots. Mineflayer mode serves a web page showing a bot's surroundings in first or third person, with drawing functions for lines and displayed primitives that can be replaced or erased by ID. Standalone mode serves a world view without requiring a bot, while headless mode renders a bot's view for streaming to a file or over TCP.

The project lists Minecraft versions 1.8.8 through 1.21.4; other versions of the same major use textures and models from the closest supported version. On online-mode servers, players can appear with wide or slim skins and capes when the server sends skin data. Examples connect the viewer with Mineflayer, a proxy, an Electron app, a Python script, and a WebSocket proxy; other examples export world sections as screenshots or 3D models. It supports server maps, live map updates, and a 3D map view. Installation uses `npm install prismarine-viewer`. The repository is identified as MIT licensed. Mineflayer and standalone modes default to six chunks of view distance and port 3000.
