Shelfab

What it does

Shelfab is the modern, open-source alternative to Calibre, designed for readers who value aesthetics over bloat. While legacy tools feel like spreadsheets, Shelfab focuses on a sleek UI and deep StoryGraph integration. It treats your TSG lists as the source of truth while using intelligent metadata fabrication to find high-res covers and ISBNs. Our unique waterfall matching links your EPUBs even if filenames are messy, all while keeping your data 100% private and local to your machine.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
