Gopherbook is a lightweight, single-binary, self-hosted web comic reader and library manager written in Go.
It is designed for people who want full control over their digital comic collection (CBZ/CBT files), including support for password-protected/encrypted archives, per-user libraries, tagging, automatic organization, and a clean modern reader.
This is free and open source software.
Features include:
- Upload & read .cbz (ZIP-based) or .cbt (TAR-based) comics directly in the browser.

- Supports 8 Megapixel images at 512MB memory limits.
- Full support for password-protected/encrypted CBZ files (AES-256 via yeka/zip) or CBT files (AES-256-CFB Openssl).
- Automatically tries all previously successful passwords when opening a new encrypted comic.
- Persists discovered passwords securely (AES-encrypted on disk, key derived from your login password).
- Extracts ComicInfo.xml metadata (title, series, number, writer, inker, tags, story arc, etc.).
- Automatic folder organization: Library/Artist/StoryArc/Comic.cbz.
- Manual reorganization via UI if needed.
- Powerful tagging system with custom colors and counts.
