Wix Headless splits a website in two. Wix keeps doing what it already does well behind the scenes: the CMS, the blog, forms, the store, bookings and members. The part visitors see is coded separately, in the framework you prefer (Astro, React or Next.js), and connects to Wix through its SDK and APIs.

On a Wix Studio site, design and content live in the same editor. On a headless site, content is still edited in the Wix dashboard, but the design and behavior of every page are code.

What you gain with a headless site

Performance. You decide what loads and when. The site doesn't carry scripts it doesn't use.
Design without template limits. Animations, interactive maps, filters or custom components, without depending on what the editor allows.
Custom integrations. The site can talk to your CRM, your ERP or an internal tool from the same codebase, without third-party widgets.
Languages and SEO under control. Routes, hreflang tags, structured data and sitemaps are defined in code, page by page.
One source of content for several channels. The Wix CMS can feed the website and an app at the same time.

What it costs

Design stops being drag and drop. Your team still edits copy, articles, case studies or products from the Wix dashboard on its own, but moving a section, creating a new page or changing the design takes someone who codes. The initial build also takes longer than a Wix Studio site, because each piece is built rather than configured.

When it makes sense

The site is an important sales or lead-generation channel, and load speed affects conversion.
You need features a template doesn't offer: calculators, configurators, maps or client portals.
The site has to connect to other systems without manual steps.
You publish in several languages or markets and want to control the SEO of each version.
There's a team, in-house or external, that will maintain the code.

When Wix Studio is the better choice

A corporate site or landing page your team wants to redesign often without developers.
Tight budgets or deadlines, where a good template done well gets the job done.
Standard online stores, where Wix Stores or Shopify already handle catalog, payments and shipping.

At ProMarketing we do both. Most of the sites we deliver are built on Wix Studio, and we save headless for the projects that justify it.

This site as an example

promarketing.com.co is built with Wix Headless and Astro. Wix stores the blog, the client case studies, the figures and the forms, and the team edits them from the dashboard. The frontend is custom code: the animated client map, the live embedded client websites, the Spanish and English routes, and the structured data on every page.

In the mobile Lighthouse test we ran after launch, the home page and the services page scored 100 in performance, accessibility, best practices and SEO, with the main content visible in 1.4 and 0.9 seconds.

How to decide

Answer three questions. What does the site need to do that a template can't? Who will change the design a year from now? How much is it worth to your business for the site to load faster or connect to your systems? If the answers point to custom features, a technical team and a measurable impact, headless makes sense. If not, Wix Studio will give you more for less.
