Lightweight: Initially, I used security products like Safe * and Yun* based on nginx, apache, and iis plugins for protection, but the plugin form had a high coupling degree.
Privatization: Later, most cloud protection services were adopted, but private deployment is affordable only for medium and large enterprises, while small companies and studios find it costly.
Privacy Encryption: During web protection, it is preferable to process local data without sending it to the cloud. The goal was to create a tool that encrypts local information and network communications for the management end.
DIY: Over the years of website maintenance and development, there were specific functions I wanted to add but couldn't achieve.
Awareness: If the webmaster has never used a similar WAF, it is inconvenient to understand who is accessing the site and what requests are being made solely from logs or nginx, apache, IIS, etc.

In short, the goal was to create an effective tool for website or API protection to handle abnormal situations and ensure the normal operation of websites and applications.
