Why Caasy?

Build individual frontends for clients that want to be in charge of their content

Maximum flexibility

Content in Caasy is organized in so-called elements. There are elements for all kind of UI elements such as a simple rich text, hero or embedded YouTube video. Even though elements are standardized, developers are free to decide how they want to present them.

Platform agnostic

Caasy offers all interfaces that are necessary to seamlessly interact with other platforms that are often found in modern build flows. It also works well with your favourite frameworks such as NextJS, Gatsby, Sapper and many more.

Intuitive editor

The Caasy editor was built with a focus on simplicity and clarity so that authors can concentrate on creating meaningful content without noise. With the editor, authors can quickly drag and drop elements to create blog posts and pages.

Simple onboarding

Caasy provides fine-grained user management that enables you as a site owner to invite other Caasy users to contribute to your site. There are different user roles to hide away technical details from users if necessary.


Build whatever you want

Caasy is suited perfectly for developers, who use modern build flows and don't want to commit themselves to a specific technology stack. The official Javascript SDK works well with modern frontend frameworks and gives developers the necessary flexibility.

Javascript SDK

With Caasy's SDK you bring your ideas to life even faster. It's a lightweight wrapper for the Caasy API and works with every framework.
