In plain English

Proxyee Down is an open-source HTTP download accelerator. It acts as a local HTTP proxy, meaning it sits between your browser and the internet, and uses multi-connection downloading to speed up file downloads by splitting each file into multiple pieces and downloading them simultaneously, then reassembling them. The project is primarily documented in Chinese. Note that the project is no longer actively maintained. The author paused development citing limited personal bandwidth, noting that Java is not ideal for client applications due to large package sizes and high memory usage. A successor project built with Go and Flutter (called Gopeed) was started as a cross-platform replacement. The original Proxyee Down was built using Java with Spring Boot and Netty (a Java networking framework) on the backend, and Vue.js with iView on the frontend. Someone would look at this repository today mainly for historical reference or to understand how HTTP proxy-based download acceleration works. Anyone needing an actively maintained tool of this type should look at the successor project Gopeed instead.
