I got tired of Calibre's heavy interface when all I needed was browsing my library and sending books to my e-reader. So I built Rulibre, a terminal UI that works directly with your existing Calibre library structure, no migration needed.
Features: - Browse books sorted by author/title with a detail panel (metadata parsed from Calibre's .opf files) - Instant search/filter across author, title, and format - Send books to Kindle/Kobo with automatic EPUB→KEPUB conversion for Kobo - Convert between formats using kepubify or Calibre's ebook-convert - Mouse and keyboard support
It's written in Rust with ratatui. Install with `cargo install rulibre`.
