Grav is intentionally designed with few requirements. You can easily run Grav on your local computer, as well as 99% of all Web hosting providers. If you have a pen handy, jot down the following Grav system requirements.

  • Web Server (Apache, Nginx, LiteSpeed, Lightly, IIS, etc.)
  • PHP 7.3.6 or higher
  • hmm... that's it really, (but please look at PHP requirements for a smooth experience)!

Grav is built with plain text files for your content. There is no database needed. A PHP user cache such as APCu, Memcached, or Redis is highly recommended for optimal performance. Not to worry though, these are usually already part of your hosting package! Web Servers

Grav is so simple and versatile that you don't even need a web server to run it. You can run it directly off the built-in PHP webserver, as long as you're running PHP 7.3.6 or later. Testing with the built-in webservers is a useful way to check a Grav install and perform some brief development, but it is not recommended for a live site or even for advanced development tasks. We've outlined how in our Installation guide. Even though technically you do not need a standalone web server, it is better to run one, even for local development. There are many great options available:


  • MacOS 10.14 Mojave already ships with the Apache Web server and PHP 7.1, so job done!
  • MAMP/MAMP Pro comes with Apache, MySQL and of course PHP. It is a great way to get more control over which version of PHP you are running, setting up virtual hosts, plus other useful features such as automatically handling dynamic DNS.
  • AMPPS is a software stack from Softaculous enabling Apache, PHP, Perl, Python,.. This includes everything you need (and more) for GRAV development.
  • Brew Apache/PHP is an alternative approach that allows a fully configurable installation with various PHP versions.


  • Laragon portable, isolated, fast & powerful universal development environment for PHP, Node.js, and more. It is fast, lightweight, easy-to-use and easy-to-extend.
  • XAMPP provides Apache, PHP, and MySQL in one simple package.
  • EasyPHP provides a personal Web hosting package as well as a more powerful developer version.
  • MAMP for Windows is a long-time Mac favorite, but now available for Windows.
  • IIS with PHP is a fast way to run PHP on Windows.
  • AMPPS is a software stack from Softaculous enabling Apache, PHP, Perl, Python,.. This includes everything you need (and more) for GRAV development.
  • Linux Subsystem is a great way to Run a linux-like environment on Windows


Many distributions of Linux already come with Apache and PHP built-in. If they're not, the distribution usually provides a package manager through which you can install them without much hassle. More advanced configurations should be investigated with the help of a good search engine. Apache Requirements Even though most distributions of Apache come with everything needed, for the sake of completeness, here is a list of required Apache modules:

  • mod_rewrite
  • mod_ssl (if you wish to run Grav under SSL)
  • mod_mpm_itk_module (if you wish to run Grav under its own user account)
  • You should also ensure you have AllowOverride All set in the <Directory> and/or <VirtualHost> blocks so that the .htaccess file processes correctly, and rewrite rules take effect.

IIS Requirements

Although IIS is considered a web server ready to run 'out-of-the-box', some changes need to be made. To get Grav running on an IIS server, you need to install URL Rewrite. This can be accomplished using Microsoft Web Platform Installer from within IIS. You can also install URL Rewrite by going to

PHP Requirements

Most hosting providers and even local LAMP setups have PHP pre-configured with everything you need for Grav to run 'out-of-the-box'. However, some Windows setups, and even Linux distributions local or on VPS (I'm looking at you Debian!) - ship with a very minimal PHP compile. Therefore, you may need to install or enable these PHP modules:

  • curl (client for URL handling used by GPM)
  • ctype (used by symfony/yaml/Inline)
  • dom (used by grav/admin newsfeed)
  • gd (a graphics library used to manipulate images)
  • json (used by Symfony/Composer/GPM)
  • mbstring (multibyte string support)
  • openssl (secure sockets library used by GPM)
  • session (used by toolbox)
  • simplexml (used by grav/admin newsfeed)
  • xml (XML support)
  • zip extension support (used by GPM)
  • For enabling openssl and (un)zip support you will need to find in the php.ini file of your Linux distribution for lines like:
  • ;
  • ;
  • and remove the leading semicolon.
  • Optional Modules
  • apcu for increased cache performance
  • opcache for increased PHP performance
  • yaml PECL Yaml provides native yaml processing and can dramatically increase performance
  • xdebug useful for debugging in a development environment
