Show HN: I built library management app for those who outgrew spreadsheets

35 hmkoyan 20 7/18/2025, 7:28:34 PM librari.io ↗
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 any additional book info the way YOU think about them

- Reading progress tracking - dates, duration, personal ratings

- Modern UI/UX - clean & actually enjoyable to use

Current Status:

- Beta version live

- Working on improving the responsiveness of the app and addressing initial user feedback

Would love feedback! Especially curious about:

- What features would make YOU actually use a library management app?

- UI/UX feedback always welcome

- Any book collectors here who'd be interested in beta testing?

Looking forward to your thoughts! Thank you in advance.

My biggest complaint with library management tools, and I think this applies to Librari as well, is the lack of multi-user support. I have a lot of books in my "home library", spread out over a few rooms. But I'm not the only person interacting with this library. Their are books on the shelves that "belong" to other people in the house, and we all joint manage the books. Sharing logins can work, but misses out on so many things that we would like to have.

My dream tool for this would allow multiple people to be "members" of a library, and be able to belong to multiple members themselves. They could collectively manage things like metadata, like what books are on the shelves, but could have individual things like ratings or tracking what they've read.

Plex is actually a really good example of this. I hope some day to find a tracker like that for my books.

Thank you for your comment and for explaining your problem in such detail. Currently, you can mark your library as public and share the link with others, but they can only see the books in it. What you're saying actually makes total sense, and I will add this feature to my backlog.

The paid version of libib.com allows you to do this. Each manager can be assigned overlapping collections to edit, but also have the ability to track status, rate and review individually.

I just want a simple/quick/easy way to scan all of the books in my house and print spine labels like the ones they use in a library.

Dewey decimal or Library of Congress or whatever. We just have too many books (mainly children's books) and I want an easy low-thought/low-friction way to identify exactly where each book should be put away.

Would this help with my problem? Is there already a solution for this?

> Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use.

That what I concluded after a cursory search of this space as well.

Hack I learned recently: take pictures of all your bookshelves. Then you can search the text on the spines (author, title) in your photo app.

This sounds like a great idea for a feature for the OP. Cool feature to kickstart the database. Take a photo. Something something AI. 150 rows filled in

The problem with library apps isn't really the app. It's trivially easy to spin up a database with all the necessary fields. The real problem with library apps (or systems) is having to actually manage/index/code/scan the books, which is a pain.

Yeah exactly, what would be awesome is an app that lets you take a picture of your book shelf and captures every book title (and author if possible)

And then after that step it could maybe build a small library with a nice, compact ui automatically

I got a barcode scanner and wrote a script to look them up in Open Library. Most of my books are found, but I don't have much weird/old stuff without barcodes. I found the process of scanning quite enjoyable tbh.

Most books are in x39.50 catalogs, I have koha at home, using the British Library, Library of Congress, National Libraries of Scotland and France, and Oxford, it finds 90% of my books, barcode scan a shelf, import, add missing books

I use https://libib.com for this use case. I didn't see it mentioned here, so figured I'd share.

I'll also mention a fun coding project that I used ChatGPT on. I created a data enriched spreadsheet out of my physical books. This could then be used to bulk import into libib for a searchable and visual digital bookshelf.

First I took photos of my bookshelves such that the spines were visible. Then I had ChatGPT vision model transcribe visible titles and authors, and guess the books based on that. Then I turned that into a CSV. Finally I had ChatGPT generate a Python script that used the Google Books API to enrich the spreadsheet with ISBNs. Finally I bulk uploaded that CSV with ISBNs to libib, and voila, I had a digitized library.

Just in case this gives you any ideas!

Thank you for your comment. Libib is indeed a well-established player in this industry. Although it suggests a lot of different functionalities/features, it lacks detailed statistics/analytics regarding users' reading activity, libraries and content. It also doesn't allow you to create your own data fields for storing information about books, authors or publishers. Regarding data extraction from photos, I considered this method initially, but then decided to leave it until there is specific feedback regarding this. Apparently, people would actually use it, as another user also pointed this out in a comment.

Glad the comment was helpful. Cool project. From one book lover to another, best of luck!

Let me save to a local database to manage my own data & backups.

This looks cool and I wish you luck but I'd probably never use something closed source for this.

Been on the lookout for an open source version but they all seem kind of unessecarily bulky or otherwise poorly maintained.

Would be interested in suggestions anyone has for whole apps or libs that work well when glued together for this purpose.

This looks like it's a website without an app, so a few questions for you:

1. How does the site perform on mobile? If it doesn't that's a non starter for a large audience segment.

2. What's the pricing? There are several free options out there for managing your book collection, so unless there's a fremium tier (which there's no concrete language about pricing on the pricing page around subscription cost or subscription tiers) less people will want to try this out.

3. Why should someone use a web based library management tool over one that's hosted locally (either as a phone app, or as a site local to your network)?

4. What problems does this solve that others have missed? I would love for that to be front and center on the landing page.

Thank you for your questions. The actual app can be used/seen only after signing in. Regarding your questions:

1. This was initially planned as a web-based application, and it still is. However, when it comes to mobile responsiveness, it's not great — something I've pointed out and am currently working on. I'll finish this work during the weekend. Creating native apps will probably make sense in future, too.

2. Yeah, as it's only the beta version at the moment, the pricing doesn't mention anything specific. I believe there will be three different pricing tiers. There will definitely be a freemium version with some limitations, e.g. a limit of one library and 100–200 books in library, and access to basic statistics only. I need to think more about the pricing in more detail, as I've only concentrated on building the product so far. However, in general, I imagine it to be as I've already described above.

3. This is a very good question, to be honest, and one that I haven't thought much about either. I would probably use a locally hosted application if it offered all the features that librari.io offers. However, I can think of some reasons why a user might want to use a web-based solution. Firstly, I assume that syncing across devices would be difficult when the application is hosted on only one device, unless it offers export/import functionality. Backup and reliability are other reasons why a user would opt for a web-based solution. I believe that the ability to share your library with other people or family members using a link, which gives them access from anywhere at any time, is a good reason to opt for a web-based solution.

4. I can outline the three most significant issues I encountered, which eventually led to the development of this app. The first is the outdated UI that most of them suggest (but of course, I'm not saying that librari.io's UI is the best). The second is the lack of library statistics and analytics (e.g. distribution tables of books, authors, etc. or content-wise and reading activity related statistics). The third is the lack of customisation. For example, the ability to add custom book, author and publisher data fields with different types, such as text, date and number, and then attach actual information to those fields when editing those entities.

I'm in an adjacent area, cataloging my huge collection of periodicals for my vintage ad collection (adretro.com). The biggest thing that helped me that I didn't see you mention but maybe I missed it: taking book cover photos to populate the inventory. OpenAI vision can easily extract the book, author and meta data. This speeds up the data entry considerably. I scan a whole box of periodicals and upload a zip of all the images. My software extracts the info. So for yours, if I just take photos of all the books on a shelf, it could handle the rest.

Thank you for your comment. Currently, there are three methods of adding a book: searching (which uses the Google Books API under the hood), manual addition (which nobody wants to do — I completely understand — but is the only option for old books that cannot be found online; I have a lot of these) and scanning the ISBN (which also uses the Google Books API). I initially thought about adding the method you suggested, where you provide a picture and then extract the information, but I decided it was not the right time to implement that. So, I left it for later, when there is any need or feedback regarding it from users. From your comment, I understand that it's something that users might actually consider using.
