My Go Module Proxy: Goproxy

Since I launched, my personal Go module proxy ( has been shut down.

Starting with Go 1.11, the Go officially introduced a new feature called Modules, which has greatly inspired my interest in project dependency management. Through an in-depth study of this new feature, I think it will bring the first Deptopia in the history of computer programming for the programming language world. After all, can you imagine a programming language without std libraries? How dreamy it will be!

And with Modules, there is also a Module proxy protocol, through which we can implement the Go module proxy (aka Dependency mirror). It is foreseeable that the future is modular, so a free, trusted, always on, and CDNed module proxy is indispensable for Go developers (especially in countries with Internet censorship). Therefore, I strictly followed the Module proxy protocol to implement a Go module proxy that basically satisfies various conditions. Its name is Goproxy. After thorough testing, it is officially announced here today.

If you trust me enough, then you can use Goproxy with me and help me improve it.
