    How to install Kirby in 5 minutes

    We are using PHP's built-in server to create a simple local developmentĀ environment.

    Download and installation

    1. We provide two downloadable kits for you to get started with.

    Starterkit

    The Starterkit is a full-blown Kirby installation with a lot of example content, blueprints, templates and more. It is ideal for new users to explore many of Kirby's options and get to know the Panel.

    Plainkit

    The Plainkit is a minimal Kirby setup with the basics you need to start a project from scratch. It is the ideal choice if you are already familiar with Kirby and want to start step-by-step.

    1. Extract the contents of the ZIP file into your server's Document root
    2. Visit your new Kirby site in your browser at yourdomain.com
    3. Visit the Panel at yourdomain.com/panel

    When copying files to a remote server via (S)FTP, make sure to copy the .htaccess file as well. By default, files starting with a dot are invisible in the filesystem, so make sure enable the display of invisible files before copying.

    Requirements

    Web server PHP

    Any of the following:

    • Apache 2
    • Nginx
    • LiteSpeed
    • Caddy

    Server Features:

    • URL rewriting
    • PHP 8.0, 8.1 or 8.2
      (PHP 8.1 is recommended)
    • Either the gd extension or ImageMagick (see below)
    • ctype extension
    • curl extension
    • dom extension
    • filter extension
    • hash extension
    • iconv extension
    • json extension
    • libxml extension
    • mbstring extension
    • openssl extension
    • SimpleXML extension

    The server OS must be POSIX compatible.

    Recommended requirements

    • PHP exif extension for support for EXIF information from images
    • PHP fileinfo extension for improved MIME type detection for files
    • PHP intl extension for the intl date handler (support for international dates) and localized number formatting

    Optional requirements

    • ImageMagick (convert binary) if you want to use the im thumbs driver. Note that the PHP exec() method must be enabled on your server in this case as well.
    • PHP apcu extension for the Apcu cache driver
    • PHP memcached extension for the Memcached cache driver
    • PHP PDO extension for connecting to databases
    • PHP zip extension for ZIP archive file functions
    • PHP zlib extension for sanitization and validation of .svgz files

    If you want to use PHP's built-in server, you have to start it up with Kirby's router:

    php -S localhost:8000 kirby/router.php

    Other servers may work, but are not officially supported.

    Browsers for the Panel

    Kirby does not modify the output of your site's templates and thus has no effect on its browser requirements. The Panel is built on modern browser features though and has a couple browser requirements which need to be met by your site's editors.

    Desktop Mobile
    • Chrome 63+
    • Firefox 67+
    • Safari 11.1+
    • Edge 79+
    • Opera 50+
    • Mobile Safari 11.1+
    • Android Browser 92+
    • Chrome for Android 92+

    Alternative ways to install Kirby

    There are alternative installation methods for advanced users who prefer to install and update Kirby using commands on the command line or in their version control tool. Check them out and use whichever method you prefer.

    If you don't have a local development environment yet and don't know what to use, check out our Local development environment recipe.

    Installation guides for webhosts

    Some providers have created dedicated guides how to install Kirby on their servers. If you are with one of these providers, keep on reading:

    Create your first account

    Kirby's control panel (aka. the Panel) comes without any pre-installed accounts. Open http://yourdomain.com/panel in the browser to start the installer and create the first account.

    For security reasons, you cannot install the Panel on a public server by default. To allow this, you can enable the panel.install option:

    Purchase license & register your installation

    Once you publish your website, you need to purchase a Kirby license. We will send you a unique license code for your domain. You can register your installation with the following steps.

    1. Open the Panel at http://yourdomain.com/panel and log in.
    2. Click on "Register" at the top.
    3. Enter your license code and your email address and press "Ok".

    Without using the Panel

    If you donā€™t want the Panel to connect to our server, registration via the Panel fails, or you are not using the Panel at all, you can download your license files directly from our licenses website:

    1. Visit licenses.getkirby.com.
    2. Log in with the email you used when you purchased the license and any order number.
    3. In the list of your licenses, click on the key you want to register.
    4. Use the "Download license file" button to download the license file.
    5. Rename the downloaded file to .license (without extensions).
    6. Place it in the /site/config/ folder of your Kirby installation.

    Updates

    To update Kirby, download the latest version and replace the kirby folder.

    Make sure to delete the media folder. It will be automatically recreated.

    If you use any plugins, make sure to update them as well.

    That's it! Because Kirby does not use a database by default, you don't have to run any database migrations.

    Kirby uses the following versioning scheme:
    {generation}.{major}.{minor}(.{patch})

    The generation number is only used for licensing. The major, minor and patch versions follow Semantic Versioning.

    Major releases (e.g 3.7 to 3.8) may contain breaking changes and deprecations. In such a case, you might have to update your code and plugins used in your installation. You can find breaking changes of a new release in the changelogs. If you are updating from older versions, multiple changelogs may apply. Always read them carefully to identify potential issues.

    Minor and patch releases (e.g. 3.7.1 to 3.7.2 or 3.7.0 to 3.7.0.1) can generally be applied without changes to your site code.

    In any case, please never update a live website directly on the server. Test updates locally first to see if something breaks.

    Updating Kirby with the advanced methods

    If you used one of the advanced installation methods, you can also use them to update Kirby:

    Upgrade from Kirby 2

    If you want to upgrade an existing Kirby 2 installation, make sure to follow all the steps from our Kirby 2 upgrade recipe.
