Perch

 Perch Runway  is a content management system with a monthly license fee, built on PHP and MySQL. It was formerly offered in two flavors with Perch being for smaller sites and Perch Runway for sites which have large collections of content. On 2022-05-02 they announced Perch Runway would be the only product they continue to develop and support. 

Perch Runway has built in support for structured content with custom fields used everywhere. If you care about web standards and clean markup, it will make you happy. The content collections and relationships make it easy to reuse, display differently and relate content items to each other.

With no in-built markup or themes, it is very designer and developer friendly.

Perch Runway is developed by Rachel Andrew and Drew McLellan. Rachel writes and speaks about CSS layout and Drew is the publisher of the 24ways advent calendar for web designers and developers. Both are strong advocates of web standards.
