What it is: OPDSy is a comic & ebook reader for Android that connects to your own self-hosted OPDS servers — Ubooquity, Komga, Kavita and Calibre-Web and merges them into a single library with per-source colour badges. I built it because Kuboo (the client I used to rely on) died and nothing reliable replaced it.

Features:

• Add multiple OPDS servers, browse them as one library; each source loads independently so one broken server never takes the whole library down
• Comics stream page-by-page (OPDS-PSE) with smart prefetch — paged/continuous/webtoon, LTR/RTL, dual-page spreads, fit-width/screen, pinch-zoom
• Ebook reader with adjustable fonts/themes (incl. sepia) and text-to-speech
• Offline downloads and continue-reading that follows you across sources
• Optional cross-device sync of library/favourites/reading progress to your own Google Drive, end-to-end encrypted — I never see your data
• File support: comics CBZ, CBR (also CB7, CBT); ebooks EPUB, MOBI, AZW3, FB2; plus PDF

Privacy: No account, no ads, no analytics or tracking at all. Server credentials stay in Android's secure storage.

Coming soon: a local reader mode, open books and comics stored directly on the device, not just from a server so it works standalone too.

I use this personally on a daily basis so im always iterating on it and adding features.
