Quick start

  1. Install required dependencies by executing pip install -r requirements.txt
  2. Execute the command: python cps.py (or nohup python 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
  5. Go to Login page

Default admin login: Username: admin Password: admin123

Runtime Configuration Options

The configuration can be changed as admin in the admin panel under "Configuration"

Server Port: Changes the port calibre-web is listening, changes take effect after pressing submit button

Enable public registration:
Tick to enable public user registration.

Enable anonymous browsing:
Tick to allow not logged in users to browse the catalog, anonymous user permissions can be set as admin ("Guest" user)

Enable uploading: Tick to enable uploading of PDF, epub, FB2. This requires the imagemagick library to be installed.


Python 2.7+

Optionally, to enable on-the-fly conversion from EPUB to MOBI when using the send-to-kindle feature:

Download Amazon's KindleGen tool for your platform and place the binary named as kindlegen in the vendor folder.

Using Google Drive integration

Additional optional dependencys are necessary to get this work. Please install all optional requirements by executing pip install -r optional-requirements.txt

To use google drive integration, you have to use the google developer console to create a new app. https://console.developers.google.com

Once a project has been created, we need to create a client ID and a client secret that will be used to enable the OAuth request with google, and enable the Drive API. To do this, follow the steps below: -

  1. Open project in developer console
  2. Click Enable API, and enable google drive
  3. Now on the sidebar, click Credentials
  4. Click Create Credentials and OAuth Client ID
  5. Select Web Application and then next
  6. Give the Credentials a name and enter your callback, which will be CALIBRE_WEB_URL/gdrive/callback
  7. Finally click save

The Drive API should now be setup and ready to use, so we need to integrate it into Calibre Web. This is done as below: -

  1. Open config page
  2. Enter the location that will be used to store the metadata.db file, and to temporary store uploaded books and other temporary files for upload
  3. Tick Use Google Drive
  4. Enter Client Secret and Client Key as provided via previous steps
  5. Enter the folder that is the root of your calibre library
  6. Enter base URL for calibre (used for google callbacks) 6 Now select Authenticate Google Drive
  7. This should redirect you to google to allow it top use your Drive, and then redirect you back to the config page
  8. Google Drive should now be connected and be used to get images and download Epubs. The metadata.db is stored in the calibre library location


If your calibre web is using https, it is possible to add a "watch" to the drive. This will inform us if the metadata.db file is updated and allow us to update our calibre library accordingly.

  1. Click enable watch of metadata.db
  2. Note that this expires after a week, so will need to be manually refresh

Docker image

Calibre Web can be run as Docker container. The latest image is available on Docker Hub.

Reverse Proxy

Reverse proxy configuration examples for apache and nginx to use calibre-web:

nginx configuration for a local server listening on port 8080, mapping calibre web to /calibre:

http {
    upstream calibre {
    server {
            location /calibre-web {
                proxy_bind              $server_addr;
                proxy_pass    ;
                proxy_set_header        Host            $http_host;
                proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header        X-Scheme        $scheme;
                proxy_set_header        X-Script-Name   /calibre-web;

Apache 2.4 configuration for a local server listening on port 443, mapping calibre web to /calibre-web:

The following modules have to be activated: headers, proxy, rewrite.

Listen 443

<VirtualHost *:443>
    SSLEngine on
    SSLProxyEngine on
    SSLCertificateFile "C:\Apache24\conf\ssl\test.crt"
    SSLCertificateKeyFile "C:\Apache24\conf\ssl\test.key"
    <Location "/calibre-web" >
        RequestHeader set X-SCRIPT-NAME /calibre-web
        RequestHeader set X-SCHEME https
        ProxyPass http://localhost:8083/
        ProxyPassReverse http://localhost:8083/

Start calibre-web as service under Linux

Create a file "cps.service" as root in the folder /etc/systemd/system with the following content:


ExecStart=[path to python] [/PATH/TO/cps.py]


Replace the user and ExecStart with your user and foldernames.

sudo systemctl enable cps.service

enables the service.
