GitHub Pages Guide: Free Static Site Hosting (2026)

Quick Answer

GitHub Pages is a free static site hosting service integrated directly into GitHub repositories. It serves pre-rendered HTML, CSS, and JavaScript files via a global CDN with automatic SSL certificates. It’s the optimal solution for documentation, portfolios, and project demos where code proximity to the repository is paramount.

Executive Summary

GitHub Pages functions as a specialized Static Site Hosting Service with integrated Continuous Deployment capabilities. Unlike general-purpose Cloud Service Providers or Platform-as-a-Service offerings, GitHub Pages strictly decouples the build environment from the runtime environment, offering a robust managed build pipeline via GitHub Actions while restricting the runtime to static asset delivery only.

Core Architecture

Platform Identity

GitHub Pages operates on a “Documentation as Code” philosophy, treating website source as an extension of the software repository. This enforces version control best practices on web infrastructure and democratizes publishing for developers already within the GitHub ecosystem.

Deployment Models

Legacy: Branch-Based Deployment

Historically, deployment was triggered by pushing to specific branches (gh-pages, master, main) or folders (/ or /docs). This method relies on an internal, opaque build process (often running Jekyll).

Modern: GitHub Actions Integration

The contemporary standard utilizes GitHub Actions:

  1. Trigger: Push or merge event initiates a workflow runner
  2. Build: Runner executes build commands (npm run build, astro build)
  3. Artifact Upload: actions/upload-pages-artifact packages static output
  4. Deploy: actions/deploy-pages pushes artifact to Pages infrastructure

Operational Capabilities

Capability Status Notes
Server-Side Rendering (SSR) Not Supported No Node.js/Python runtime
Static Site Generation (SSG) Full Support Core capability
Incremental Static Regeneration Not Supported Entire site must rebuild
Edge/Serverless Functions Not Supported Call external APIs only
Long-Running Processes Not Supported No background workers
WebSockets Not Supported HTTP/1.1 or HTTP/2 only
Cron Jobs Supported (via Actions)** GitHub Actions Scheduled Workflows
Persistent Storage Not Supported Read-only filesystem at runtime
Custom Domains Supported CNAME/A records with auto SSL
SSL Certificates Supported (Managed) Let’s Encrypt, enforced HTTPS
CDN Supported Global delivery network
Preview Deployments Partial/Manual Requires manual GitHub Actions config

Framework Support

Full Support

Framework Implementation Details
Angular Builds to SPA, requires baseHref setting, works via angular-cli-ghpages
Astro Static-first architecture, default output target, zero-JS hydration works natively
Qwik Qwik City offers dedicated static adapter, serializes state to HTML
React (Vite) Standard SPA builds, requires 404.html hack or HashRouter for client-side routing
SolidJS Compiles to efficient static JavaScript/HTML, SolidStart includes static adapter
Svelte Compiler-based framework, produces optimized vanilla JS bundles
Vue.js Standard Vue SPAs (Vite/CLI), requires configuration for history mode routing

Partial Support (Functional Downgrade)

Framework Limitations
Next.js Requires output: 'export'. Loses API Routes, Middleware, Image Optimization, ISR
Nuxt Requires nuxt generate (SSG). Loses server-side API routes and SSR
Remix New “SPA Mode” allows deployment but disables server-side loaders/actions
SvelteKit Requires adapter-static. Loses server endpoints and dynamic SSR
Hono SSG helper (hono/ssg) exports static routes, dynamic request handling fails

No Support

Framework Reason
Django Ninja Python backend requiring WSGI/ASGI server process
Elysia Backend framework for Bun requiring persistent runtime
Express.js Node.js backend server requiring persistent runtime
FastAPI Python backend requiring Uvicorn/Gunicorn
Laravel PHP framework requiring PHP runtime and web server
Litestar Python ASGI framework requiring persistent server process
NestJS Node.js backend framework requiring server runtime
Spring Boot Java framework requiring JVM

Pricing and Strategic Value

Free Tier

  • Hosting: Completely free for public repositories
  • Included: Unlimited builds (for public repos), bandwidth within soft limits
  • Build Rate: Soft limit of 10 builds per hour (legacy builds)

For Pages on private repositories:

Tier Price Features
GitHub Pro $4/month (individuals) Enables Pages for private repos
GitHub Team $4/user/month Enables Pages for organization-owned private repos
GitHub Enterprise $21/user/month Enterprise features

Best Use Cases

  1. Documentation: Hosting README-based docs (MkDocs, Docusaurus) directly from the repo
  2. Open Source Demos: Public repositories get unlimited Actions minutes for live demos
  3. Personal Portfolios: Free tier with custom domain support for professional resumes
  4. Static Blogs: Jekyll, Hugo, Astro align perfectly with the architecture

Anti-Patterns (Avoid For)

  1. Dynamic Web Apps: Applications needing complex backend logic, database connections, or authentication
  2. E-Commerce: Full e-commerce logic cannot be securely hosted
  3. High-Frequency Updates: Real-time data updates without client-side fetching

Operational Limits

Limit Value
Source Repository Size Recommended 1 GB limit
Published Site Size Maximum 1 GB for final artifact
Bandwidth Soft limit of 100 GB per month
Build Rate Soft limit of 10 builds/hour (legacy)

Runtime Constraints

  • Max Execution Time: N/A (Runtime) / ~6 Hours (Build)
  • Cold Start Impact: None (static files served from cache/disk)
  • Memory Limits: N/A (Runtime) / ~7 GB (Build)

Comparison

vs. Netlify

Aspect GitHub Pages Netlify
Static Hosting Free (public repos) 100 GB (Starter)
Preview Deployments Manual configuration Automatic for every PR
Serverless Functions No Yes (Node.js, Go)
Edge Functions No Yes (Deno runtime)
Background Functions No Yes (up to 15 minutes)

vs. Vercel

Aspect GitHub Pages Vercel
Primary Focus Static sites Next.js/Frontend Cloud
Free Tier Unlimited (public) 100 GB bandwidth, 1M edge requests
SSR Support No Full (serverless/edge)
Functions No Yes (Vercel Functions, Edge Functions)
Build Minutes Unlimited (public) 6,000/month (Hobby)

vs. Cloudflare Pages

Aspect GitHub Pages Cloudflare Pages
Build Integration GitHub Actions Native Git integration
Preview Deployments Manual Automatic for PRs
Functions No Workers (Edge compute)
Bandwidth 100 GB soft limit Unlimited

Migration Path

For projects outgrowing GitHub Pages:

  1. To Netlify/Vercel: Better for dynamic features, serverless functions, automatic previews
  2. To Cloudflare Pages: Better for edge computing and Workers
  3. To DigitalOcean App Platform: Better for always-on compute and background workers

Conclusion

GitHub Pages stands as the foundational pillar of static site hosting for the modern web development ecosystem. Its profound integration with GitHub Actions allows for a seamless “commit-to-publish” pipeline that drastically reduces operational overhead for documentation, portfolios, and static content.

However, its rigorous adherence to the static paradigm creates a hard ceiling for complexity. The lack of Server-Side Rendering, API routes, and edge functions renders it unsuitable for the new wave of full-stack meta-frameworks in their default configurations.

Verdict: Use GitHub Pages for content that lives alongside code—documentation, project sites, and portfolios. For dynamic applications requiring backend logic, it must be paired with external backend services or replaced by more capable PaaS alternatives.
