GitHub Pages

GitHub Pages is a free hosting service that turns your GitHub repository into a live website. It serves static content directly from your repository, making it the simplest way to publish documentation, portfolios, project landing pages, and blogs without paying for hosting or managing servers. Every GitHub user and organization gets access to this service automatically.

How GitHub Pages Works

GitHub Pages takes HTML, CSS, and JavaScript files from a specific branch or folder in your repository and serves them as a website. There is no server-side processing — no PHP, no database queries, no Node.js runtime. The files are served exactly as they exist in your repository, distributed globally through GitHub's CDN for fast load times.

Every time you push changes to the configured source branch, GitHub Pages automatically rebuilds and redeploys your site within minutes.

Types of GitHub Pages Sites

User/Organization Sites

Each GitHub account gets one site at username.github.io:

• Repository must be named exactly username.github.io
• Content is served from the main branch root
• URL: https://username.github.io

This is ideal for personal portfolios or organization home pages.

Project Sites

Every repository can have its own GitHub Pages site:

• Content served from a branch (main or gh-pages) or the /docs folder
• URL: https://username.github.io/repository-name
• No special repository naming required

Setting Up GitHub Pages

From Repository Settings

1. Navigate to Settings → Pages
2. Under "Build and deployment," select your source:

• Deploy from a branch — Choose branch and folder
• GitHub Actions — Use a custom build workflow

1. Save and wait for deployment

Quick Start with HTML

Create an index.html in your repository:

Push it to main, enable Pages, and your site is live.

Jekyll Integration

GitHub Pages has built-in support for Jekyll, a static site generator written in Ruby. You do not need to install anything locally — GitHub builds Jekyll sites automatically.

Create a minimal Jekyll site:

_config.yml:

index.md:

GitHub automatically builds this into a full website with navigation, styling, and a blog feed.

Using Custom Themes

Apply a Jekyll theme without any local setup:

Popular themes: Cayman, Minimal, Architect, Slate, Midnight.

Deploying Framework Sites (React, Vue, etc.)

For sites built with modern frameworks, use GitHub Actions:

Custom Domains

Replace username.github.io with your own domain:

1. Add a CNAME file to your repository containing your domain name
2. Configure DNS at your domain registrar:

For www.yourdomain.com:

For apex domain (yourdomain.com):

1. Enable "Enforce HTTPS" in repository settings — GitHub provides free SSL

Common Use Cases

Developer portfolio: Showcase your projects, skills, and experience at yourname.github.io.

Project documentation: Host API docs, user guides, and tutorials alongside your code.

Technical blog: Write posts in Markdown, let Jekyll or a framework generate the site.

Event or organization pages: Landing pages for meetups, conferences, or community groups.

Limitations

• Static content only (no server-side code execution)
• Repositories must be under 1 GB
• Sites have a soft bandwidth limit of 100 GB per month
• Build time limited to 10 minutes
• No private Pages on free accounts (public repositories only for free tier)

Key Takeaways

GitHub Pages provides free, automatic hosting for static websites tied directly to your repository. It supports everything from simple HTML files to Jekyll-generated blogs to framework-built applications deployed via GitHub Actions. Custom domains and HTTPS come free, making it a complete hosting solution for documentation, portfolios, and any project that produces static output.
