Quick start

  1. Install dependencies by running pip3 install --target vendor -r requirements.txt (python3.x). Alternativly set up a python virtual environment.
  2. Execute the command: python3 cps.py (or nohup python3 cps.py - recommended if you want to exit the terminal window)
  3. Point your browser to http://localhost:8083 or http://localhost:8083/opds for the OPDS catalog
  4. Set Location of Calibre database to the path of the folder where your Calibre library (metadata.db) lives, push "submit" button
    Optionally a Google Drive can be used to host the calibre library -> Using Google Drive integration
  5. Go to Login page

Default admin login:
Username: admin
Password: admin123

Issues with Ubuntu: Please note that running the above install command can fail on some versions of Ubuntu, saying "can't combine user with prefix". This is a known bug and can be remedied by using the command pip install --system --target vendor -r requirements.txt instead.


python 3.x+

Optionally, to enable on-the-fly conversion from one ebook format to another when using the send-to-kindle feature, or during editing of ebooks metadata:

Download and install the Calibre desktop program for your platform and enter the folder including program name (normally /opt/calibre/ebook-convert, or C:\Program Files\calibre\ebook-convert.exe) in the field "calibre's converter tool" on the setup page.

Download Kepubify tool for your platform and place the binary starting with kepubify in Linux: \opt\kepubify Windows: C:\Program Files\kepubify.

Docker Images

Pre-built Docker images are available in these Docker Hub repositories:

Technosoft2000 - x64

LinuxServer - x64, armhf, aarch64

  • Docker Hub - https://hub.docker.com/r/linuxserver/calibre-web

  • Github - https://github.com/linuxserver/docker-calibre-web

  • Github - (Optional Calibre layer) - https://github.com/linuxserver/docker-calibre-web/tree/calibre

    This image has the option to pull in an extra docker manifest layer to include the Calibre ebook-convert binary. Just include the environmental variable DOCKER_MODS=linuxserver/calibre-web:calibre in your docker run/docker compose file. (x64 only)

    If you do not need this functionality then this can be omitted, keeping the image as lightweight as possible.

    Both the Calibre-Web and Calibre-Mod images are rebuilt automatically on new releases of Calibre-Web and Calibre respectively, and on updates to any included base image packages on a weekly basis if required.

    • The "path to convertertool" should be set to /usr/bin/ebook-convert
    • The "path to unrar" should be set to /usr/bin/unrar

  • caliBlur!


    Soooo... i've been crazy busy since we last spoke and i've learned some shit :) My goal atm is to build a consistent ui across all user facing apps in my organizr install. Since plex is the biggest part of that, is closed source, and i actually like the design the most anyway, ive decided to make everything fit with it. To that end, I started a repo called layer#Cake to build a css layer on top of existing self hosted apps like organizr, ombi, and now calibre-web, and i've built my own themes (blur) with the plex design language as a guide, into each.

    layercake can be installed on the webserver which means you don't have to worry about messing w source or breaking updates, and since its all hosted on git, updates are automatic (using rawgit cdn network to push the .css). That being said, there are some definite advantages to building layercake directly into these apps (as we have done with organizr and ombi) so please let me know if that has any appeal to you. Anyway, I was kind of hoping to have this mostly finished before posting here, but I'm hitting a couple forks in the road, and your willingness to add a couple things for me will change the way i finish this theme. (If it's not too much trouble to attach a class to <body> for each url dir is the most important for example).

    Anyway, still a wip, and mobile doesn't work at all yet, but the desktop layout is 90% finished. You can check it out by adding this to your nginx location block:

        proxy_set_header Accept-Encoding "";
        sub_filter '</head>' '<link rel="stylesheet" type="text/css" href="https://rawgit.com/leram84/layer.Cake/dev/CSS/caliBlur-Demo.css"> </head>';
        sub_filter_once on;

    Lemme know what you think, and like i said, if you're willing to add a few (very small) adjustments for this, i can make it even better! Cheers!

  • Uploading PDF results in Calibre Web restarting [Docker]

    Uploading PDF results in Calibre Web restarting [Docker]

    I'm trying to upload a PDF file to Calibre, but ever time I upload, I get a 500 error and see the following in the calibre-web logs:

    [2019-01-29 18:00:25,749] INFO in web: Starting Calibre Web... [2019-01-29 18:00:26,126] INFO in server: Starting Gevent server

    This is the second PDF file encountering this issue. I'm not sure what the issue is, exactly, as there doesn't appear to be any debug output prior to the server restarting. What can I do to provide more information to determine what the issue is?

  • New view for series

    New view for series

    Hi, I've been working on a quick proof of concept to improve the listing of the series. Basically instead of having a list of series titles I would have something like this:

    Screenshot 2019-07-27 12 23 14

    Now in order to integrate it smoothly I want to have your opinion as to how this should behave. Here are my thoughts:

    1: Having another menu called "Collection" next to serie witch would display the new view

    ➖A bit redundant ➕You get to keep both view and it's easy to switch between them

    2: Having a switch on top of the serie page to switch between views

    ➕Easy to switch between views ➖If you prefer one way or another you'll be stuck with what the default would be ➖Extra ui

    3: Having a setting on your user pref to choose between one view or another.

    ➕Once setup, no extra step or cluttering to get your view. ➖More difficult to switch between different style

    My personal preference goes for option 3, but I would like to hear your thoughts on that.

    Also Things to consider and features I'd like to add to this view.

    cover selection: At the moment I just display the cover of the first book in the collection. We could imagine an option to select

    • First
    • Last
    • First unread

    Badge display: At the moment I don't display any badge but there is going to be one and it could display 2 things:

    • Total books in the collection
    • Total unread books in the collection

    Convert only from edit metadata page not working

    First off, when I run a new setup of calibre-web, I always seem to get this HTTP error page when I add the initial setup info even though it starts to function fine afterwards:

    Internal Server Error The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

    BUT, after going to the edit metadata page of a book and trying to convert from XXX to MOBI/AWZ/etc I get the same HTTP error page. It also does not do the convert, no Task is created, and the log file shows:

  • Refactor worker thread / tasks

    Refactor worker thread / tasks

    Issue: #1577

    As mentioned in that issue, the current worker thread that handles background tasks is monolithic and non-extendable without modifying the file itself. This PR aims to address this and make the background task system more modular.

    This is a fairly big PR, but I can answer any questions and work with the maintainers to address any issues noted. Here's a quick rundown of the changes:

    • The worker thread is now simply a queue that runs and manages tasks. That's its only function.
    • Each task that is added is a mostly self-contained class that extends from CalibreTask. This class contains the logic specific to running that task
      • CalibreTask is an abstract class that provides basic boilerplate logic for all tasks. This allows each task to simply focus on the stuff they need to run, while the CalibreTask manages things like meta data (eg: start/stop time), wrapping errors, and providing a common API that all tasks should have.
    • Since each task is self contained and there isn't any reason to check the "task type" via if statements, I've removed the TASK_* constants. Each task now has their human-readable type defined in their class. This might affect localization - would be open to hearing any concerns over this and if there's an issue, how to address it
    • Aside from those, the actual logic of the tasks hasn't changed much (although, I will say that I've removed the CalibreDB add_format task due to #1565 being merged in, which allows the database to be safely utilized within other threads)

    With the changes in this PR, it should be theoretically possible for third party code to be added to calibre-web (in some sort of future plugin system) and be able to utilize the background worker thread. It simply needs to provide the queue with it's own task class extended from CalibreTask and it'll work like any other task

    I've tested this stuff to the best of my abilities, and everything seems to be working well. I would definitely invite others to test it though.

    Some things that I haven't been able to test:

    • Any gdrive integration. Theoretically, it should work, but I don't have that integration set up and honestly it looked really involved that I just didn't bother. 🙄🤗
    • Apparently calibre-web has tests... see tests/, but have no idea how to run them / if there's even tests written for these systems. So if there's any automated unit testing, they haven't been run (and indeed, they would probably have to be re-written due to the refactoring)
    • I developed this on python 3.6. I think this would also work with 2.7 and the other versions that calibre-web supports, but I'm not positive. I don't have much experience with maintaining code that must be compatible with 2.x and 3.x, so any additional eyes on this would be beneficial

  • No Book-Cover with Kindlegen sending the Book via E-Mail

    No Book-Cover with Kindlegen sending the Book via E-Mail

    Hey there, I'm using the calibre-web Docker image from technosoft2000 but I think this is no error with the image. When I'm sending a Book to my kindle via Calibre-Web, everything is going well. It send the book and my kindle downloads the book. No problem with that. But unfortunately, it doesn't download or shows me the book cover. When I transfer the eBook via Calibre directly, it shows me the cover.

    Is this a normal behavior? If not, do you need anything else to investigate my problem? As I said, I'm running an Container via Docker. Here are the versions how they are displayed at the about page:

  • Define timings for thumbnail generation

    Define timings for thumbnail generation

    I just stumbled upon this PR. Sounds like a great idea.

    Please let the user define the timings/intervals.

    I do not need it to look for missing images every 5 minutes. Once per day or week would be enough for me. Maybe let the user define a specific time instead of an interval? And the expire time could even be a couple of month, in my opinion.

    My main concern is that my HDD would not go into standby when calibre-web is scanning for thumbnails all the time. 😄

    Just my 2 cents as a casual user. I barely use calibre-web as you might have guessed. 😉

  • [Question] Default locale for new users imported via LDAP?

    [Question] Default locale for new users imported via LDAP?

    This is more of a question than an issue, I apologize if it is not possible to do this kind of thing.

    When I was importing users from LDAP, the locale was a big problem since the correct one was not always selected (even though I understood that it is taken from the browser). With the latest update, being able to modify multiple users at the same time was a blessing, but when it comes to managing more than 2k users it becomes a bit tedious.

    Currently, due to problems with a new ISP, I cannot use the LDAP import option, and despite the fact that in the last issue that I opened I implemented the Google's Oauth solution, I feel that eventually if I have the opportunity to return to LDAP I will not think twice, which is why I am encouraged to ask:

    Is possible to select the default locale for new users imported via LDAP? or... can be some part of the code fixed to do that?

    EDIT When I opened the issue #1504 you provided me with a script (at that time) to help me import users; that same script (some time later) I wanted to implement it, since it allowed me to define the locale with which the user account would be imported, but I had no success executing it. After reviewing documentation (since I did not want to bother) I could modify it so that "it works" (the problem was that my instance was running with domain and https, while the script needed an ip address + port and pointed to a http link) indicating that the import process had been carried out successfully, but when checking in the application users did not appear.

    Is there any possibility of being able to modify that same script to take advantage of the static selection of the locale?

  • Question on Author sort by series

    Question on Author sort by series

    I've been using Calibre-web for a little while now and for the most part think it's quite good. I have a question regarding how books are sorted for display.

    I know that from the main page I can select from different sort parameters. Choosing the Author sort does that but books seem to be displayed in a random order within that. I would like to be able to sort by series / series index within the author but can't find a way to do that. I can sort by series index if I view a series but would prefer if it was the possible to do it as the default author sort.

    Is there a setting somewhere that controls this? I've looked in the app and multiple online forums and can't find any reference to that.

    Is your feature request related to a problem? Please describe. As a user, I'm always confused because I do not know which identifiers are supported out of the box by Calibre-Web. I discovered a few by trial and error, and eventually I found a reference in db.py

    Describe the solution you'd like A dropdown list for picking identifiers in the "Edit Metadata" view would be awesome

    Describe alternatives you've considered Alternatively, an info tooltip or a footnote linking to the full reference list might suffice.

    I am using a seedbox to host my calibre-web server so I don't have control over the calibre installation and server configuration. The app is a bundle (calibre and calibre-web) and access to the web server is done through a thin client (so I will appear as coming from localhost). When I want to generate the Kobo Auth URL I have the error message:PLease access calibre-web from non localhost to get valid api_endpoint for kobo device. Is there a way to bypass this error or generate the API a different way? Any reason for restricting the API generation from localhost?
