Grimmory

Grimmory is a digital library for your ebooks, PDFs, comics, and audiobooks. It's the community fork of BookLore, continuing where that project left off with the same polished library management and reading experience, and adding audiobook support on top.

Organise your collection into libraries and smart shelves, let Grimmory fetch metadata automatically, and read in the browser with a built-in reader that supports annotations. Sync reading progress to Kobo devices and KOReader, browse your library from any OPDS-compatible reading app, or fire a book straight to your Kindle.

How do I access Grimmory?

Grimmory is available:

• From your dashboard: https://your-username.elfhosted.com
• Directly: https://your-username-grimmory.elfhosted.com

Migrating from BookLore

If your ElfHosted account already has BookLore data, Grimmory migrates it automatically the first time it starts: your library database, covers, metadata, users, and reading progress are copied across (BookLore's own data is read, never modified, so BookLore keeps working until you cancel it). Sign in to Grimmory with your existing BookLore credentials.

A few notes:

1. The migration runs once, on first start, and only if Grimmory has no data of its own yet.
2. For the cleanest copy, stop or cancel BookLore before subscribing to Grimmory. A running BookLore is tolerated, but a quiet one is safer.
3. Prefer a fresh start instead? Ask elfbot to set GRIMMORY_SKIP_BOOKLORE_MIGRATION=true before Grimmory first starts.
4. Your actual book files live under /storage and are shared by both apps, so nothing is duplicated or moved.

How do I use it?

Sign in and create your first library, pointing it at a folder under /storage containing your books. Grimmory scans the folder, fetches metadata, and builds your shelves from there.

To add new books, either upload them through the web UI, or drop files into the BookDrop watched folder and Grimmory will import them automatically.

The full feature tour lives in the upstream documentation.

Grimmory also works with

• [Calibre Web][calibre web]

• Audiobookshelf

• Readarr

• OpenBooks

What users say..

We're rocking some excellent TrustPilot Reviews, and here's what some of our usersfriends say..

I am new here, but today I learned realized that Elfhosted is one of the best free and open source software communities I've seen, and FOSS communities have been at the center of my life since the 90s (Perl, PHP, Symfony, Drupal, Ethereum, etc.). Great open software built by great people who care = great community, and that is something special.

You've done an amazing job @Funky Penguelf with the platform you provide and this place has an awesome mix of active community caretakers and software creators that I've seen here so far like BSM, Spoked, LayeZee and other elf vengers. Keep up the energy, productivity and community and take time to enjoy it and appreciate each other!

As a happy Elfhosted customer—who also self hosts MANY things across about 10 severs (dedicated, VPSes, and VMs running on Synology), I wouldn’t switch to self hosting the services I get from Elfhosted. They just work with very little effort configuring things, and the support the owner and his team provides is second to none. Plus I love being part of a fledgling—but quickly growing—enterprise.

I’ve been using this service for a while now, and honestly, it’s a game-changer compared to anything else I’ve tried for managing my media library. The support is fantastic—super quick, and if the staff aren’t around (which rarely happens), the community steps up right away. I can’t imagine going back to any other platform.

Before this, I had my own setup with a NUC, NAS, and tools like Sonarr and Radarr. It worked pretty well for a while, and my internet speed was high enough to stream without any buffering. But in the end, it wasn’t worth the time or headache of managing all the storage and keeping everything running smoothly.

Now, with this service, everything runs smoothly in 1080p+ with no buffering issues. The interface is really easy to use, which makes managing everything a breeze. Plus, having a whole community of smart people available for guidance is a huge bonus.

I was sold from the start, which is why I quickly upgraded from a 1-month to a 3-month subscription, and I’m planning to switch to a 1-year plan soon. This service totally pays for itself, and I’m sure you won’t be disappointed. It’s been really impressive.

Best possible options for anyone looking for the do-it-all option along with the best customer service ive experienced in this space so far. Id rate it a 6 if I could but its limited to 5/5...

(responding to a discussion re the cost of ElfHosted vs mainstream streaming / self-hosting):

I didn't know that the goal of this project was to compete with large companies running/renting entire DCs. I was under the impression that the goal of this project was to manage the updating of almost selfhosted applications on a shared platform with other users. Basically, be my sysadmin for me.

That being said, paying for services is the 'easy button'. There is a real world cost incurred for the time saved. Time is money. Time is the most valuable currency that exists. Once time is spent, it's forever lost, one cannot retrieve it again (yet). In my mind, there are 3 options for use of time with respect to: mainstream, selfhosting, elfhosted.

• mainstream - my time is valuable and I don't want curated content and I don't care what content that I have the ability to consume. I only like what's popular.

• elfhosted - my time is valuable, I want my own curated content without being forced to browse past the same damn entry 500 times just to find out that I can't watch the movie I want because it's not available in my current location or was removed last week from mainstream providers.

• selfhost - I care about costs and I have nothing but time to waste or I want to learn about the backend of the systems involved. I'll pay for my own VPS/homelab, electricity, manage the OS, manage app updates, figure out how to make the apps talk nice to each other, create my own beautiful frontend.

I know how much my time is worth, does that reddit poster know how much their time is worth? Without knowing what you are worth, you can't make effective capital expenditures with respect to the time it will take to recoup the capital.

I know I don't need elfhosted at all for my use case. I choose to stay with elfhosted because it's my 'easy button'. It's an efficient capital expense for the amount of time it saves me managing my own hardware, apps and saves me electricity costs. I'm also in a situation where I don't have upload bandwidth from my home to serve HD content to myself remotely. If I lived back in a city, I would still be here. My time is worth $$/hr.
