Manga readers use KamiYomu to build a private, self-hosted library: it fetches chapters from the websites they already follow, archives them locally, and serves everything back through a clean web reader on any device. The discovery flow runs on Crawler Agents, small plugins that teach KamiYomu how a particular source site lists series, chapters, and pages, so searching and fetching metadata happens inside the same interface as reading. Downloads land in a structured local archive, and reading picks up where you left off with history, filters for your library, and weekly views that surface new chapters and fresh releases. When a series is complete, export it as CBZ, PDF, or ZIP and take the files anywhere, no account or cloud library involved. Your e-reader and phone apps join through the built-in OPDS catalog, the same standard used by Moon+ Reader and KyBook, while a Swagger-documented API exposes the collection to your own scripts. Scheduled jobs keep watched series current in the background, checking sources and pulling new chapters without you babysitting tabs.
