Pages CMS

A user-friendly, Git-based CMS designed for static site generators with GitHub integration.

What is Pages CMS?

Pages CMS is an open-source, Git-based content management system that provides a user-friendly editing interface for websites built with static site generators. It connects directly to GitHub repositories, allowing content editors to update Markdown files, images, and data without needing to use Git commands or code editors.

Pages CMS is designed for development teams who want to give non-technical collaborators access to edit content on Jamstack websites. By storing all content in Git, the platform maintains the benefits of version control, collaboration, and developer workflows while providing an accessible editing experience.

The architecture follows the Git-based CMS pattern: content remains in your repository, and Pages CMS provides a frontend layer for editing.

Architecture and Technology

Pages CMS operates as a thin layer on top of Git repositories.

Core Components

  • Web Interface: React-based editing interface
  • GitHub Integration: OAuth connection to read/write repository content
  • Configuration File: YAML-based schema definition in the repository
  • Media Handling: Image uploads committed directly to the repository
  • Markdown Processing: Edit frontmatter and body content through forms

How It Works

  1. Connect: Users authenticate with GitHub and grant repository access
  2. Configure: A .pages.yml configuration file defines content collections
  3. Edit: Non-technical users access the web interface to edit content
  4. Commit: Changes are committed directly to the repository
  5. Deploy: CI/CD pipelines rebuild the static site (Netlify, Vercel, GitHub Pages)

No Backend Infrastructure

Unlike traditional CMSs, Pages CMS:

  • Does not store content in its own database
  • Does not require hosting,it’s a client-side application
  • Relies entirely on GitHub’s API and storage

Typical Use Cases

Pages CMS is commonly used for:

  • Developer blogs: Personal and team blogs using Hugo, Astro, or Eleventy
  • Documentation sites: Technical docs managed by non-developer contributors
  • Marketing websites: Jamstack sites where marketing teams update content
  • Portfolios: Designer and agency portfolios built with static generators
  • Small business sites: Brochure sites with occasional content updates
  • CMS Conf website: Used for this very site (cmsconf.com)

Strengths

  • Git-native: All content stays in your repository with full version history
  • No vendor lock-in: Content is Markdown/YAML files; switch CMSs freely
  • Free and open source: No hosting costs for the CMS itself
  • Simple setup: Add a config file, connect GitHub, start editing
  • Familiar for developers: Integrates with existing Git workflows
  • Works with any SSG: Jekyll, Hugo, Astro, Next.js, Nuxt, Eleventy, etc.
  • Media management: Upload images that are committed to the repo

Limitations and Trade-offs

  • GitHub dependency: Requires GitHub; other Git providers not supported
  • Repository size limits: Git is not ideal for large media libraries
  • Build times: Every content change triggers a full site rebuild
  • Real-time collaboration: Not suited for simultaneous multi-user editing
  • Content preview: Requires separate preview deployment setup
  • Smaller feature set: Fewer features than full-featured headless CMSs
  • Public repositories: Free tier has limitations; private repos may need paid plans

SEO, Performance, and Content Governance

SEO

As a Git-based CMS, SEO is handled at the static site level:

  • Content includes frontmatter fields for meta title, description, and social images
  • Static sites typically have excellent SEO performance
  • No CMS-side SEO features; all handled by the static site generator

Performance

  • Zero CMS overhead: No database queries or server-side rendering
  • Static output: Resulting sites are pure HTML,fastest possible delivery
  • CDN-friendly: Static sites deploy globally with instant caching
  • Build performance: Depends on static site generator and hosting provider

Content Governance

  • Git history: Full version control with blame, revert, and branching
  • Branch workflows: Content editors can propose changes via pull requests
  • Collaboration: GitHub’s collaboration features apply to content
  • Access control: Managed through GitHub repository permissions

Localisation

  • File-based i18n: Create language-specific folders or files
  • SSG support: Leverage static site generator’s i18n capabilities
  • No built-in translation management: Handled at the file/folder level

Tips and Best Practices

  • Structure content thoughtfully in folders that map to your site’s architecture
  • Use clear field names in the configuration for editor usability
  • Set up preview deployments (Netlify Deploy Previews, Vercel Preview) for content review
  • Leverage Git branching for content staging before production
  • Optimise images before upload to manage repository size
  • Document the editing workflow for non-technical team members
  • Consider media hosting externally (Cloudinary, Imgix) for large sites

Who Should (and Should Not) Choose Pages CMS

Best Fit For

  • Jamstack developers wanting to add CMS capabilities
  • Small teams with occasional content updates
  • Projects already using GitHub for development
  • Blogs, documentation, and marketing sites
  • Developers who want Git as the source of truth

Not Ideal For

  • Large content operations with many editors
  • Sites requiring complex content relationships
  • Projects needing real-time preview or collaboration
  • Media-heavy sites with large image/video libraries
  • Teams uncomfortable with GitHub as a dependency

Common Alternatives

  • Netlify CMS (Decap CMS): Similar Git-based approach, more mature, community-maintained
  • Tina CMS: Visual editing, real-time preview, deeper Git integration
  • CloudCannon: Premium Git-based CMS with more features
  • Forestry: Legacy Git-based CMS (predecessor to Tina)
  • Strapi: Full-featured headless CMS for more complex needs

Pages CMS offers a streamlined solution for teams who want to add editing capabilities to static sites without the complexity of a full content management platform.
