Start the embedded Svelte web application and JSON API for a startup archive:
zim serve <file.zim-or-library-name>The server uses server.host, server.port, and the configured timeouts. The startup file may be outside the configured library, but later HTTP library selections are limited to that file or canonical .zim files beneath library.path.
zim serve simple-wikiPress Ctrl+C to shut down gracefully. zim ui <file> is a deprecated compatibility alias and runs exactly the same server.
The web UI supports library selection, lexical search, optional semantic search, article navigation, and archive resources. Article HTML is isolated in a sandboxed iframe rather than inserted into the application document.
