Sulu CMS
Sulu CMS and our custom React frontend have been proven to be a good, reliable, and flexible solution for our own content management needs as well as for our customer projects.
You can read some blog posts covering Sulu on our blog. This may further help you understand why we are using Sulu as content management system.
Sulu CMS is a full content life-cycle focused content management system based on the Symfony framework and React.
Since Sulu CMS is a first-class Symfony citizen, it follows all the best practices which made it easy for our Symfony developers to get used to it.
Having the possibility to either use Twig templating or a custom React frontend (via the Sulu Headless Bundle) is another bonus for us. This way we can choose whatever makes the most sense for our projects.
