Grav vs ProcessWire

Since Grav is built with PHP, it can be hosted on almost all web hosting providers. If the provider supports Wordpress, they also support Grav.

Supports Twig for templating with Parsedown for fast Markdown and Markdown Extra support.

Well designed, easily usable and modern admin panel is a boost as it lets Clients edit the content easily.

YAML-based page headers allow you easily add custom dynamic fields to your content.

Documentation is not an afterthought! Grav has a dedicated documentation site plus loads of tutorials and guides.

Command line tools such as dependency installation, cache clearing, user creation, and backups.

You will always find one to respond politely in the forums. Sometimes even the creator Ryan Cramer himself.

ProcessWire is heavily based on custom fields. All objects (Pages) inside ProcessWire are based on extensible templates comprised of fields that can be easily defined. Many useful fields come prebuilt and they can be extended with modules.

Processwire is extremely easy to learn. Consider this:
echo $pages->get('title=Hello World')->title; // "Hello World"
echo $pages->get('title=Hello World')->parent->title; // "Home"
echo $pages->find('Template=Category')->count; // 126
echo $pages->find('Template=Category')->each('title'); // ['Audio', 'Video' …]

Selectors are so powerful but yet so easy.

Check out the cheatsheet.

The API is jQuery like;
// find some pages:
$pages->find('template=skyscraper, architect=john, sort=title')->limit(4);

// mutate
$pages->get('title=Hello You')->set('title', 'HelloWorld')->save();
$pages->get('title=Old')->trash(); // trash page

// check user…
$user->isLogedin();
echo $user->name; // guest
$session->login($name, $pass);
$session->logout();

// redirect
$session->redirect($url);

The way you fetch, access and manipulate objects (Pages) in ProcessWire is extremely powerful and easy. You can receive any page and its custom fields, filter, travers, add…

By default, ProcessWire comes with 0 assumption on how you handle the output. You have 100% freedom on how you want to develop the frontend. Want to plain output stuff, go ahead. Want to use any number of Templating Engine, do it. Just use as Headless-CMS, okay!

Either using the modules already available or writing your own module, using the jQuery-like API.
