    Hey HN, I know reading books isn’t everyone’s thing, but it’s certainly been mine for as long as I can remember. Unfortunately, I felt like the online book space was missing a platform that does the book community justice. Goodreads is the go-to "social platform", but if you've been on Goodreads before, you'll probably agree that it's not all that social, and overall not all that exciting. So I set out to build what I personally was looking for (but could never find). The goal: to give the book community a more social and streamlined alternative to Goodreads or StoryGraph. We also felt like…

    Since 2005, Goodreads has been the default book tracking site, connecting millions of readers. But let’s be real—it’s barely changed in 20 years. It’s the same site it was, just with more ads. Still no half-star ratings. No proper DNF (Did Not Finish) option. UI still looks like it's from 2005. Amazon owns it and doesn't care. So I built Kaguya, a modern alternative, over the past 9 months. What’s live: Custom shelves (Organize however you want) Rich-text reviews (format your thoughts properly) 10-star rating system (More nuance than 5 stars) DNF, On-Hold, and other reading statuses Likes,…

    TLDR: Librario is a book metadata API that aggregates data from Google Books, ISBNDB, and Hardcover into a single response, solving the problem of no single source having complete book information. It's currently pre-alpha, AGPL-licensed, and available to try now[0]. My wife and I have a personal library with around 1,800 books. I started working on a library management tool for us, but I quickly realized I needed a source of data for book information, and none of the solutions available provided all the data I needed. One might provide the series, the other might provide genres, and another…

    Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their…

    I'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…
