What Prismarine Viewer is
Prismarine Viewer is a free web-based viewer for Minecraft servers and bots, with modes for inspecting a bot’s surroundings, viewing a world without a bot, and rendering a bot’s view without a browser display. Mineflayer mode serves a web server that shows the bot’s surroundings in first or third person. It also provides drawing functions, including adding lines and replacing or erasing displayed primitives by ID. Standalone mode serves a view of a world without requiring bot mode. Headless mode renders a bot’s view and can stream it to a file or over TCP.
The project lists Minecraft version support from 1.8.8 through 1.21.4. Other versions within those major versions 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 show connections with Mineflayer, a proxy, an Electron app, a Python script, and a WebSocket proxy; other examples export world sections as screenshots or 3D models. Server maps, live map updates, and a 3D map view are supported. Install with `npm install prismarine-viewer`. PrismarineJS is named as the package author, and GitHub identifies the repository license as MIT.
