The "开发预览" Chrome plugin enables users to access their locally developed web pages through an external network. By caching the content of the locally developed web pages, this tool allows for seamless external access. Each QR code generated by the plugin remains valid for 10 minutes, providing a convenient and efficient way to preview your work online.

This plugin serves as a valuable tool for developers looking to test their websites in real-world conditions without the need for complex setups. With the ability to preview locally developed websites externally, developers can streamline their testing process and ensure optimal performance across different networks.
