As Templately is the ultimate cloud for WordPress website templates, it is perfectly compatible with most WordPress themes. When you create a website using the ready templates from Templately, there are no theme-related dependencies. So, there are no limitations, you can insert the ready templates no matter what kind of WordPress theme you have installed on your website. However, for the best user experience, we recommend using themes that are lightweight and flexible.
If you are using page builders, then the only recommended themes that we would suggest are those that are well compatible with your page builder. For instance, when you are using the ready Elementor templates from Templately, we would recommend using themes that are Elementor compatible.
