How to Speed Up GitHub Access with Mirrors, CDN Proxies, and Hosts Tweaks

1. GitHub Mirror Access

Two public mirror sites provide a full copy of GitHub repositories, allowing browsing, cloning, and downloading without contacting the official domain.

https://github.com.cnpmjs.org

https://hub.fastgit.org

These mirrors are kept in sync with the upstream GitHub.

2. GitHub File Acceleration via Cloudflare Workers

Deploy a Cloudflare Workers script to accelerate git clone, release archives, and other project files. The service runs on Cloudflare’s edge network and includes CDN caching, so no own server is required.

https://gh.api.99988866.xyz

https://g.ioiox.com

If the demo endpoints are unavailable, the open‑source project gh-proxy‑GitHub can be self‑hosted (source URL: https://hunsh.net/archives/23/).

3. GitHub Accelerated Download Tool

Paste any GitHub URL into the input box of the following web tool to download the resource through a proxy:

http://toolwa.com/github/

4. Custom GitHub Acceleration Domain

Use the service at https://github.zhlh6.cn. After entering a GitHub repository URL, the site generates an accelerated address that works with git ssh, git clone, and other Git commands.

5. Chrome Extension for GitHub Acceleration

A browser extension can rewrite GitHub requests to use the accelerated domains. The extension may require manual installation.

6. GitHub Raw File Acceleration

The raw file domain is raw.githubusercontent.com. If other acceleration methods do not affect this domain, replace it with the static CDN reverse‑proxy service:

Use raw.staticdn.net instead of raw.githubusercontent.com to speed up raw file downloads.

7. GitHub + JsDelivr

JsDelivr can serve static assets from GitHub repositories, but it cannot fetch binary files (e.g., .exe, .dmg) that are attached to releases. Therefore it is suitable only for static files, not for accelerating release downloads.

8. Download via Gitee Fork Import

Import a GitHub repository into Gitee and download it from the Gitee mirror.

Visit https://gitee.com/ and log in.

Select “Import from GitHub/GitLab” on the top navigation.

Paste the GitHub repository URL and click “Import”.

After the import finishes, browse the imported repository and download the code. Use the “Refresh” button to sync updates from the original GitHub repo.

9. Manual Hosts File Acceleration

Bind CDN IP addresses to GitHub domains by editing the system hosts file.

Obtain the IP for github.global.ssl.fastly.net (e.g., 199.232.69.194) via http://github.global.ssl.fastly.net.ipaddress.com/#ipinfo.

Obtain the IP for github.com (e.g., 140.82.114.4) via https://github.com.ipaddress.com/#ipinfo.

Edit the hosts file (Windows: C:\Windows\System32\drivers\etc\hosts, Linux/macOS: /etc/hosts) and append the two mappings.

199.232.69.194 github.global.ssl.fastly.net
140.82.114.4 github.com
