Kuroco mean?


In Japan, a Kuroco is a backstage helper of traditional theatre plays. While the show takes place on the front stage, a Kuroco makes sure that things run smoothly in the back, enabling that everything runs flawlessly and actors can focus on their performance.

This is the main concept behind Kuroco – a headless CMS that lets you focus on the distribution of personalized content and the development of a delightful front-end without having to worry about manually updating content, correct language display, or slow performance. Kuroco is built on the knowledge and technology of RCMS, a Japanese CMS we have been developing and successfully running since 20 years.

Development philosophy

The current trend in system development is to separate the systems and combine them with APIs, because the repeated, fine-grained development and release approach works better in the current business climate than monolithic system development. However, in terms of backend development, web services such as the CMS generally lack the functionality to implement this kind of development process.

At Diverta, we believe that monolithic system development is incompatible with the current era of continuous improvement and renewal. This is why we have released Kuroco, whose API-centered design enables maximum flexibility for the user. Through this service, we strive for a world in which all developers can enjoy free development.
