Citadel – a Calibre-compatible eBook management app
Hey folks! This winter I've been building Citadel to scratch my itch of managing ebooks without using Calibre. Calibre is incredibly powerful, but it's slow and awkward to use. I dreamed of writing a native app (and originally tried this in Swift), but ran into issues building the UI. Plus, whatever I built would only work on macOS. I started writing Citadel using Tauri (Svelte on the frontend + Rust on the backend) to have a cross-platform desktop app. Plus, Citadel supports running in a headless / webbrowser mode. You can self-host a Citadel server that manages your library, and…

In plain words
Citadel is a cross-platform eBook management application designed as a faster, simpler alternative to Calibre. Built with Tauri for desktop use and compatible with Calibre libraries, it offers both a native interface and a web-based mode for self-hosted server management accessible from anywhere. The tool is aimed at eBook enthusiasts seeking more streamlined library management than existing solutions provide.

I rewrote my Mac Electron app in Rust2025 · desktopdocs.com · ▲597A year ago, my co-founder launched Desktop Docs here on HN. It's a Mac app we built with Electron that uses CLIP embeddings to search photos and videos locally with natural language. We got positive feedback from HN and our first paying customers, but the app was almost 1GB and clunky to use. TLDR; rebuilding in Rust was the right move. So we rewrote the app with Rust and Tauri and here are the results: - App size is 83% smaller: 1GB → 172MB - DMG Installer is 70% smaller: 232MB → 69.5MB - Indexing files is faster: A 38-minute video now indexes in ~3 minutes instead of 10-14 minutes -…

I built library management app for those who outgrew spreadsheets2025 · librari.io · ▲92I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
