Compare Drupal 8 vs. Grav

Drupal 8 is a partial modernisation of the legacy Drupal CMS with a few parts of Symfony under the hood. Usability improvements were not the focus and to the end user Drupal 8 is very much like Drupal 7.

Grav is a fresh flat-file database which is easy to install. It uses a number of Symfony components and is very fast to get started with.

• Based on stable legacy with critical APIs in place
• A large number of ready made modules (for Drupal 7)
• Large mass of developers brings stability for purchasers

• Fast to install and get started with
• Extensible via Plugins, Skeletons and Themes
• A fresh codebase, no PHP4 cruft here

• A custom architecture based on Symfony Components, proprietary module structure
• Usability of admin interface not very good and remains tightly coupled to Drupal
• Suspect to security issues due to custom implementation and popularity (see Drupalgeddon)

• Limited use cases due to flat-file approach
• Limited developer base
• Needs more work to round the edges in real-world use
