NoirPanther is a native reading app for the books and comics you keep on your own server. EPUB, PDF and comics, offline downloads, reading progress that follows you across devices — and nothing between you and your library.
Built natively for each platform and designed around long reading sessions.
Native Readium-based reader: themes, fonts, typography, margins, columns, scroll or pages, table of contents, bookmarks, highlights and notes.
Paged, vertical and horizontal modes, double-page spreads, pinch-zoom, tap zones, page slider with thumbnails. Manga opens right-to-left by itself — the reading direction comes from the file.
Download books and read with no network. Files are encrypted at rest, with keys kept in the system secure storage (Keychain on iOS and Mac, Keystore on Android). A server owner can allow offline reading even for people who may not download files.
Positions read offline are queued and delivered later. If the server moved on meanwhile, you choose what to keep.
OPDS 1.2 and 2.0 feeds with browsing, search and authentication — alongside your main server.
Discussions with reactions, replies and message editing, right next to the book.
iOS home and lock-screen widget “Reading now” — jump straight back into the book.
Four dark and two light themes. The default is Vibranium — violet on near-black, the one you are looking at.
Phone, tablet and a true desktop layout on Mac and wide iPad: master–detail browse and two-column book pages.
The app connects to the NoirPanther server — an open-source fork of the Stump media server. You install it wherever you like: a home server, a NAS, a VPS. Your books never leave your machines.
ghcr.io/vint1024/noirpanther for amd64 and arm64 — up and running in minutes; the server tells you when a new release is out
A public demo server with a small library: public-domain classics in English and Russian, PDF picture books and comics. Open it in the browser, or add it in the app as a server.
https://demo.noirpanther.kuvshinov.indemodemo1234The demo account is read-only and its reading progress is reset once a day. Please do not enter any personal data there. The books are in the public domain (Standard Ebooks, Wikisource, Internet Archive, Wikimedia Commons); the Pepper&Carrot comic is by David Revoy, licensed CC BY 4.0.
We do not hide where things come from. The server is a fork of an open-source project and stays open. The mobile app is original, closed-source code.
Yes. NoirPanther is a client: it reads the library from a NoirPanther (Stump-compatible) server that you or someone you trust runs. To look around first, use the public demo server.
Yes. Turn on “Stump compatibility” in the app settings: the app then uses only the standard Stump API and hides what exists only in our fork — encrypted offline reading without download permission, book clubs, series merging and the per-book reading direction. So you are free to run either server: the original Stump (source on GitHub) or the NoirPanther fork.
No. There is no analytics, advertising or tracking SDK in the app, and we run no backend that the app reports to. Server addresses and credentials are stored only on your device. See the Privacy Policy.
EPUB, PDF and comic archives (CBZ/CBR and similar) — whatever the server can serve. EPUB files can also be imported and read without a server.
Pricing will be announced with the store release. The server is free and open-source.
No. NoirPanther is an independent project. The server is a fork of Stump; the app is written from scratch and is not affiliated with the Stump project.
