Bento, by Satori Studio, is one the most feature-rich free WordPress themes I’ve ever come across. It’s packed with advanced features typically found only in expensive premium themes. The theme’s creator is actually an Envato Elite author, meaning that their WordPress themes have made at least $75,000 from buyers on ThemeForest.
Bento includes everything you would expect to find in a premium WordPress theme, including a responsive design, retina-quality images, drag-and-drop content builder, AJAX post loading, unlimited color and font combinations, post format support and well documented (and translation-ready!) code.
The theme offers a wide array of ready-to-go page layouts, allowing it to serve as an online store (with WooCommerce integration!), magazine, blog or gallery with very little setup. The available templates provide such an extensive amount of flexibility that you may never need another WordPress theme again.
