Web acceleration solution “KUSANAGI Stack”

We develop and provide the “KUSANAGI Stack” web acceleration solution.

KUSANAGI is an ultra-fast virtual machine that runs CMS such as WordPress fast and securely.
Compared to the standard LAMP environment*, the speedup is approximately 2,330 times faster when page cache is used, and approximately 20 times faster when page cache is not used.
High performance and stability reduce opportunity loss during access concentration and cloud costs.

WEXAL® is an “acceleration engine” for web systems.
It improves Core Web Vitals and PageSpeed Insight scores and enhances UX (user experience).
Optimization of resources not only speeds up display, but also reduces the amount of data transferred.

The strategy AI “David” generates ”web acceleration strategies” in real time. It automates advanced display acceleration tuning, which was previously performed by engineers, and significantly reduces operational costs related to acceleration.
