NateCueDecap CMS: The Complete Guide to Git-Based Content Management
1. What Is Decap CMS?
Decap CMS (formerly known as Netlify CMS) is an open-source content management system designed specifically for static websites built with SSGs (Static Site Generators).
Its defining characteristic: it’s a Git-based CMS. Instead of storing content in a database (like WordPress or Strapi do), Decap stores everything - posts, configuration, images - directly in your Git repository as Markdown, JSON, YAML, or TOML files.
Why the Name Change?
In February 2023, Netlify transferred the project to PM TechHub to let Netlify focus on infrastructure. The project was renamed to Decap CMS, but the core technology and 100% backward compatibility with Netlify CMS configurations were preserved.
2. The Editor Experience
Decap CMS has a clean, writing-focused interface. Here’s what working with it looks like:
- Login: Uses GitHub, GitLab, or Bitbucket OAuth - or Netlify Identity if you prefer.
- Dashboard: Shows a list of “Collections” you’ve defined - think Blog Posts, Pages, Team Members.
- Editor:
- Left side: input fields for your content (Rich Text, Date, Image, Relation…)
- Right side: Real-Time Preview - see the rendered result as you type
- Media Library: Manage images stored directly in Git, or connect external services like Cloudinary or Imgix.
3. What Makes It Worth Using
1. Completely free. No database costs, no monthly fees, no vendor pricing tiers to worry about.
2. Version control built in. Every content change is a Git commit. Want to restore a post from three weeks ago? git revert. It’s that simple - and it works in a way that no traditional CMS can match.
3. Editorial Workflow. Decap supports a Draft - In Review - Ready approval flow. When a piece of content is approved and merged into the main branch, your CI/CD pipeline (Vercel, Netlify, etc.) automatically rebuilds the site. The publish button is literally a Git merge.
4. Fast and secure by default. The final site is static HTML - nothing to hack, no SQL injection surface, no server vulnerabilities to patch. Security posture is dramatically simpler than a PHP-based CMS.
5. Developer-friendly configuration. Everything is defined in config.yml. Adding a new content field means editing one file, not running a database migration.
4. When to Use Decap CMS (and When Not To)
Good fit:
- Personal blogs, documentation sites, company landing pages
- Small teams (1-5 content editors)
- Projects already using Next.js, Hugo, Jekyll, Docusaurus, or Astro
Not a good fit:
- Sites with tens of thousands of posts (Git repos get slow at that scale)
- Applications requiring complex backend logic - e-commerce at scale, social networks
- Non-technical editors who are genuinely intimidated by anything involving GitHub (even though Decap hides most of the Git complexity behind a clean UI)

FAQ
What's the difference between Decap CMS and Sanity?
Sanity stores content in its own cloud database (Content Lake) with real-time collaboration features. Decap stores everything in your Git repository as plain files. Decap is free with no vendor lock-in; Sanity has a generous free tier but is a paid service at scale. For simple blog-style content, Decap is often simpler. For complex, multi-author editorial sites, Sanity offers more power.
Do editors need to know Git to use Decap CMS?
No. Decap CMS provides a visual editor that completely hides Git from content editors. They write in a rich text editor, click publish, and the CMS handles the commit and push behind the scenes. The Git integration is entirely transparent to non-technical users.
Can I use Decap CMS with Astro?
Yes. Decap CMS works with any SSG, including Astro. The CMS writes Markdown files to your repository, and Astro reads them through Content Collections. The combination is particularly clean because both tools are Git-native and file-based.
What happens to my content if I stop using Decap CMS?
Nothing bad. Your content is just Markdown and YAML files in your Git repository. You can switch to a different CMS, a different SSG, or just edit the files directly - everything stays in your control. There’s no proprietary format or export step needed.
