githubusercontent.com

githubusercontent.comis a content-delivery domain operated by GitHub (a Microsoft subsidiary), used exclusively to serve static assets — raw source files, images, release artifacts, and Git LFS objects — from GitHub repositories, keeping user-supplied content isolated from the maingithub.comorigin for security reasons.

Key facts

Owner / operator: GitHub, Inc. (subsidiary of Microsoft Corporation)
TLD:.com— gTLD
Primary purpose: CDN origin for raw repository content, user-uploaded images, release assets, and Git LFS objects hosted on GitHub
Status: active

Notable subdomains or services

The domain is not a user-facing hosting service, but several well-known subdomain patterns exist:

raw.githubusercontent.com////— serves raw (unrendered) file content directly from any public repository branch or commit
avatars.githubusercontent.com— serves user and organisation avatar images
camo.githubusercontent.com— GitHub's image-proxy service (rewrites external images in Markdown through this origin)
objects.githubusercontent.com— serves Git LFS objects and release binary assets
user-images.githubusercontent.com— stores images uploaded by users in issues, pull requests, and comments
private-user-images.githubusercontent.com— same as above for private/authenticated contexts

Related domains

github.com— main GitHub platform (code hosting, pull requests, Actions, etc.)
github.io— GitHub Pages hosting; user sites follow the pattern.github.io
githubassets.com— serves GitHub's own UI static assets (JS, CSS, icons)

📈 Tranco rank: #715
