ComicCatcher is a desktop OPDS (v2.0 and v1.2) browser and comic reader. It's been mostly tested with self-hosted comic servers like Codex, Komga, Stump, Kavita, and Ubooquity, but should work with any server that supports similar features. Comics can be streamed page-by-page, or downloaded and read offline. Written in Python and runs on Linux, Windows, and macOS. ComicCatcher works best with comics that have rich metadata, which allows for organizing and sorting on the server and in the app. OPDS v2.0 servers provide a better experience.
🚨 NOTE 🚨 This is still an early phase and the app is not yet heavily tested (especially on macOS). If you encounter issues, or something doesn't make sense, please don't hesitate to report it. 🙈
- Streamed Reading Support: Read page-by-page with no download. (Depends on server support of OPDS v2.0 Digital Visual Narratives Profile (DiViNa) or OPDS-PSE (v1.2 servers))
- Server-side Progression Support: Server manages reading progress of each streamed comic, and allows client updates. (Depends on sever support for OPDS v2.0 Progression (proposal))
