BookOrbit
BookOrbit organises your books and reads them back to you anywhere. Ebooks, PDFs, comics, and audiobooks all get a reader in the browser, and your progress, highlights, and reading status follow you between the browser, a Kobo, and KOReader. Start a chapter on one, finish it on another.
Around that sit fourteen metadata providers, OPDS and Send-to-Kindle delivery, multi-user accounts, reading statistics and achievements, and automatic sync out to Hardcover, Readwise, and StoryGraph.
When does managed BookOrbit make sense?
- You read on a Kobo or in KOReader, and want progress and highlights to survive moving between devices rather than starting again each time.
- Your library is mixed. Ebooks, comics, and audiobooks live in one place instead of one app each.
- You already run a book library and want to move. BookOrbit imports directly from Grimmory, BookLore, Audiobookshelf, and Calibre-Web-Automated, so you are not rebuilding your collection by hand.
- Pair it with Shelfmark to search for and fetch books, then have them land in BookOrbit's Book Dock for review.
Note
BookOrbit and Grimmory cover similar ground. Grimmory is the community continuation of BookLore; BookOrbit is a separate project whose distinguishing feature is the three-way Kobo, KOReader, and browser sync. Running both is fine, and BookOrbit can import from Grimmory if you decide to consolidate.

Info
BookOrbit is an open-source tool. ElfHosted provides hosting infrastructure only. Users are responsible for their use of this service in compliance with applicable laws and third-party terms of service.
Initial setup
The first time you open BookOrbit it asks you to create an admin account, and for a setup token. Enter:
That token only works while your instance has no accounts on it, and the account-creation page is behind your ElfHosted login, so nobody else can reach it. Once your account exists the token stops working entirely.
After that:
- Set a password you are happy with. This is BookOrbit's own login, separate from your ElfHosted one, because e-readers and OPDS apps sign in with it.
- Create a library and point it at where your books live. The folder picker starts at
/storage, so an rclone-mounted remote appears under /storage/rclone/<mount>/. - Scan the library, and let the metadata providers fill in covers and details.
Getting books in
There are three routes, and most people end up using more than one.
Book Dock is a watched folder. Anything dropped into storage/config/bookorbit/book-dock/ (via FileBrowser) is picked up, has its metadata extracted, and waits in the Book Dock screen for you to confirm the match and file it into a library. Files are only ingested once they have finished copying, so a slow upload will not be half-imported.
Shelfmark can deliver straight into that folder. In Shelfmark's settings, set the save path to /bookorbit-bookdock, and books you fetch there appear in BookOrbit for review.
Drag and drop in the web interface, for one-off additions.
Reading on a Kobo or in KOReader
This is what BookOrbit is built around, and both directions work: progress and annotations made on the device come back, and progress made in the browser goes out.
- Kobo: BookOrbit stands in front of the Kobo sync service, so your own library shows up on the device alongside anything bought from the store. Setup is per-device, from Settings.
- KOReader: install the BookOrbit plugin on the device for an on-device catalogue with search and download, plus progress and annotation sync.
- OPDS: for any other reading app, generate a personal OPDS feed and point the app at it.
Highlights from all three merge into one searchable hub, and can be exported as Markdown, CSV, or JSON, or pushed to Readwise as you make them.
Sharing with family
BookOrbit has its own user accounts with per-library permissions, so you can give someone access to part of your collection without giving them your ElfHosted login. Registration is closed by default; you invite people from the admin settings.

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.
