The most trusted Go module proxy in China. has fully implemented the GOPROXY protocol. And it's a non-profit project supported by China's well-trusted cloud service provider Qiniu Cloud. Our goal is to provide a free, trusted, always on, and globally CDNed Go module proxy for Gophers in China. Please subscribe to our real-time and historical data on system performance at only focuses on the development of the web application that serves at If you're looking for a dead simple way to build your own Go module proxy, then you should take a look at Goproxy which is based on.

Happy coding, Gophers! ;-)


Go 1.13 and above (RECOMMENDED)

Open your terminal and execute

$ go env -w GO111MODULE=on
$ go env -w GOPROXY=,direct


macOS or Linux

Open your terminal and execute

$ export GO111MODULE=on
$ export GOPROXY=


$ echo "export GO111MODULE=on" >> ~/.profile
$ echo "export GOPROXY=" >> ~/.profile
$ source ~/.profile



Open your PowerShell and execute

C:\> $env:GO111MODULE = "on"
C:\> $env:GOPROXY = ""


1. Open the Start Search, type in "env"
2. Choose the "Edit the system environment variables"
3. Click the "Environment Variables…" button
4. Under the "User variables for <YOUR_USERNAME>" section (the upper half)
5. Click the "New..." button
6. Choose the "Variable name" input bar, type in "GO111MODULE"
7. Choose the "Variable value" input bar, type in "on"
8. Click the "OK" button
9. Click the "New..." button
10. Choose the "Variable name" input bar, type in "GOPROXY"
11. Choose the "Variable value" input bar, type in ""
12. Click the "OK" button



Why create

Due to the Chinese government's network supervision system, there're lot of modules in the Go ecosystem that Chinese Gophers cannot go get, such as the most famous And the speed of getting modules from GitHub in the mainland of China is a bit slow. So we created to make Gophers in China better use Go modules. In fact, since has been CDNed globally, you can use it anywhere.

Is it safe to use

Of course, as with all other Go module proxies, we just cache the modules as they are, so we can assure you that they will never be tampered with on our side. However, if you still can't fully trust us, then you can use the most trusted checksum database to ensure that the modules you get from us have not been tampered with, since already supports proxying checksum databases.

Is legal in China? is a business-supported project rather than a personal project. And it has been ICP filed in the MIIT of China (ICP license: 沪ICP备11037377号-56), which means it's fully legal in China.

Why not use

Since has been blocked in the mainland of China, so no. However, if you're not in the mainland of China, then we recommend that you give priority to using, after all, it looks more official. Once you enter the mainland of China, we hope that you'll think of in the first place, which is the main reason why we choose the .cn as the domain name extension.
