The most trusted Go module proxy in China.

28,509,117 module versions cached


 Blazing Fast

We are using Qiniu Cloud CDN to accelerate our service globally without placing any bandwidth limits. With thousands of CDN nodes and 100Gbps+ single-node bandwidth, you will be given the ability to download module versions at a blazing fast speed.

 No Limit

We do not just place no bandwidth limits. Furthermore, we have not placed any rate limits. This means that you can use our service in any scenario, like CI/CD. You can even use our service as an upstream proxy, just like does.

 Full Featured

We are always using the latest Go version, even the unstable version. Because we provide cutting-edge feature support. In particular, we support proxying the default checksum database You don't need to do anything extra, it just works.

 Data Visualized

For everyone to better understand the activity of all modules in our service, we have launched the very first Statistics API of the Go module proxy world. With the decent RESTful API design, you will be able to easily query statistics for all module versions in our service.

Open your terminal and execute

Your code is always yours, so we provide you with the coolest self-hosted Go module proxy building solution in the world. By using Goproxy, a minimalist project, you can easily add Go module proxy support to any existing web service, you know that is built on it.

Create a file named goproxy.go

package main

import (


func main() {
	http.ListenAndServe("localhost:8080", &goproxy.Goproxy{
		GoBinEnv: append(
			"GOPROXY=,direct", // Use as the upstream proxy
			"",         // Solve the problem of pulling private modules
		ProxiedSUMDBs: []string{
			"", // Proxy the default checksum database

and run it

$ go run goproxy.go

then try it by setting GOPROXY to http://localhost:8080. In addition, we also recommend that you set GO111MODULE to on.

That's it, a fully functional Go module proxy is successfully built. In fact, you can use Goproxy with your favorite web frameworks, such as Gin and Echo, all you need to do is add one more route. For more advanced usage please check the documentation.
