YAO is an open-source application engine, written in Golang, in the form of a command-line tool that can be downloaded and used immediately. It is suitable for developing business systems, website/APP API, admin panel, self-built low-code platforms, etc.

YAO adopts a flow-based programming model to implement various functions by writing YAO DSL (Logical Description in JSON format) or using JavaScript to write processes. The YAO DSL can be written in several ways:

1. Purely hand-written

2. Use automated scripts to generate contextual logic

3. Use the visual editor to create by "drag and drop"

Yao's name is derived from the Chinese character yao (yáo), the basic symbol that makes up the Eight Trigrams. The gossip is a symbol system created by the ancient god Fuxi after observing and summarizing the laws of nature, which can refer to everything. Yao has two states of yin and yang, like 0 and 1. The transformation of yin and yang of Yao drives the replacement of gossip, so as to summarize and record the development law of things.
