Kii Cloud is a mobile backend platform from Kii Corporation that combines standard mBaaS features with IoT device management. It handles user authentication, data storage, and push notifications while adding the Thing-IF SDK for connecting and controlling IoT devices.

The platform focuses on IoT, letting teams build unified backends that serve both mobile apps and connected devices. Server Code runs custom JavaScript on the server for workflows needing admin-level access or scheduled execution. The C language SDK supports embedded systems and real-time operating systems for industrial equipment and resource-constrained devices.

The platform, documentation, and developer portal are available in both Japanese and English, with support teams handling inquiries in either language.
