Jocala Catalog — Calibre Library Browser

Browse your Calibre ebook library from your Windows, macOS, or Linux PC. Find a book fast, see its details, then read it on your Kobo: open a book already on the device, or sync a missing one over with one click.

Features

• ★ Read on Kobo — open a book directly on your Kobo, or sync it to the device if it is not there yet.
• Fast library grid — scroll thousands of books with covers. Tested against a 6,755-book library.
• Search that helps — by title, author, series, or tag, with a form that fills the dropdowns for you.
• Book detail — cover, author, publisher, ISBN, and description at a glance before you read.
• Live Calibre library — reads your Calibre database on your PC or over the LAN. No import step, no duplicates.
• Windows, macOS & Linux — same app on all three platforms. Same features, same flow.

Build from source

One tree, three targets. Qt Widgets shell (qt/) over the Rust engine (crates/catalog-core + crates/catalog-ffi); crates/catalog-cli is a headless acceptance harness.

• Windows (static Qt 6.11.1): mirror qt + crates/ + Cargo.toml/Cargo.lock, run qt/build-catalog-windows.ps1, then qt/package-catalog-windows.ps1.
• Linux (system Qt via qt6-base-dev): run qt/build-catalog-linux.sh, then qt/package-catalog-linux.sh (TGZ).
• macOS (static Qt 6.11.1): run qt/build-catalog-macos.sh (universal app), then qt/package-catalog-macos.sh (signed + notarized DMG).

Verify: cargo test --workspace, cargo clippy --workspace --all-targets -- -D warnings.
