Headless CMS: Manage content without compromise

You want to change text and images yourself without making your website slower or less secure? A headless CMS does exactly that — content management as easy as a Word document, performance like a race car.

Simply explained

What is a headless CMS?

With WordPress, design and content live in one system. That sounds convenient, but has a downside: every design change can affect content — and vice versa. Plugins slow down the system, and security vulnerabilities affect everything at once.

A headless CMS separates these two worlds. You edit your content in a clean, organized interface — enter text, upload images, save. Done. Your website design is built separately and is therefore lightning-fast and secure.

Think of it this way: the CMS is your kitchen where you prepare the dishes. The website is the restaurant where they are served. Both work independently — when you create a new dish, you do not need to remodel the restaurant.

For you as a business owner, this means: you manage content as easily as before, but your website stays fast, secure, and future-proof. No plugin updates, no security patches, no risk that an update breaks your site.

The comparison

Headless CMS vs. WordPress

Both systems let you edit content. But the differences in performance, security, and maintenance are significant.

Headless CMS

  • Website loads in under 1 second
  • No public login page (secure)
  • No plugin chaos — just your content
  • Design and content independent of each other
  • Minimal maintenance effort

WordPress (traditional)

  • Load time often 2–5 seconds
  • /wp-admin well-known — frequent attack target
  • Dozens of plugins needed, each a risk
  • Design changes can break content
  • Regular updates and maintenance required

FAQ

Frequently asked questions

What exactly is a headless CMS?
A headless CMS separates content management from your website design. You edit text and images in a simple interface — like WordPress — but the website itself is built separately and is therefore faster, more secure, and more flexible.
Is a headless CMS harder to use than WordPress?
No, often even easier. Modern headless CMS systems have a clean interface where you only see the fields you need. No plugin chaos, no confusing settings — just your content.
Which headless CMS does 0gravity use?
We primarily work with Storyblok, Sanity, and Decap CMS. The choice depends on your requirements: Storyblok offers a visual editor, Sanity provides maximum flexibility, and Decap CMS is a free option for simpler projects.
Can I switch from WordPress to a headless CMS?
Yes. We migrate your existing content cleanly into the new system. Your texts, images, and page structure are preserved. The migration takes 1–3 weeks depending on scope.
How much does a headless CMS cost?
Many headless CMS are free in their basic version (e.g., Decap CMS, Sanity Free Tier). Premium plans cost from CHF 20–80/month. Compared to WordPress with premium plugins and hosting, you often save money.
Do I need a headless CMS if I only have 5 pages?
Not necessarily. For very simple websites, we can maintain content directly in code — faster and cheaper. A headless CMS becomes worthwhile once you want to regularly change content or run a blog.
Is a headless CMS secure?
Very secure. Since the CMS is completely separated from the frontend, there is no publicly accessible login page that can be attacked. Your content is retrieved via a protected API — significantly more secure than WordPress with its well-known wp-admin address.
