Pimcore

Pimcore is a comprehensive open-source platform that combines CMS, PIM (product information management), DAM (digital asset management), and customer data tools in one system. It's built on Symfony and PHP, making it a solid choice for teams who already use that stack. The unified platform means managing products, assets, and content all in one place.

It's designed for larger organizations with complex content and asset workflows, especially in e-commerce and retail. The open-source model keeps costs down, and you can self-host or use their cloud service. The breadth of features can feel overwhelming for simple sites, but for multi-channel publishing it's powerful.
