Most companies start their website on Wix, Squarespace, or WordPress. It makes sense. You can be online within a few days, pay a few dozen euros per month for hosting and a template, and you do not need to understand code. But then a day comes when the website stops keeping up. It loads slowly, cannot be adjusted to match business needs, and you start Googling “Wix vs Next.js”.
This article is not about Wix being bad. Wix is good at what it was built for. It is about recognizing when you hit its limits and knowing when it is time to move on.
When Wix is exactly what you need
If you are a small company or freelancer who simply needs an online presence, Wix is a reasonable choice. For €15 to €50 per month, you get a complete website with hosting, an SSL certificate, basic SEO features, and an administration panel where you can update text and images without anyone’s help.
This is a legitimate use case, and there is nothing wrong with it. Wix solves exactly this problem: getting a business online quickly, cheaply, and without a developer. If your website is simply a company presentation with five pages and a contact form, there is no reason to spend thousands of euros on a custom solution. Wix handles it, and you can focus on your business.
The problem starts when your website becomes more than just a digital business card.
Where Wix starts hitting its limits
There are four areas where website builders eventually become a problem. Not all at once, but gradually. Most companies notice them only when they start costing them money.
Loading speed
Wix websites are generally slower than custom-built websites. The reason is simple: the platform has to support millions of different websites, so every site carries a large amount of code that it does not necessarily need.
Core Web Vitals, the metrics Google uses to measure user experience, are difficult to consistently achieve in the green zone on Wix. When Google determines that your website is slow, it can negatively affect your rankings. For ecommerce websites, every second of delay can translate into lost conversions.
Limited customization options
Wix works extremely well as long as you are doing what the platform was designed for. Adding a page, changing text, replacing an image: simple.
But what happens when you need a custom booking form with logic that cannot be created in the editor? Or an integration with your accounting system? Or a specific user journey that cannot be built inside the platform?
That is when you discover you are inside a cage. A nice, functional cage, but still a cage.
SEO with larger websites
Wix has basic SEO tools and has improved significantly over the years. However, when a website grows to dozens or hundreds of pages, includes a blog, or requires multiple languages, its SEO management starts becoming limiting.
You do not have full control over URL structures, individual page performance, or how content is indexed. At a certain point, platform limitations start holding you back more than the content you create.
Platform dependency
Your website is not fully yours. It runs on Wix, and if Wix changes pricing, features, or terms tomorrow, you have to accept those changes.
For a small website, this is not a major issue. For a website that represents a significant part of your business, it becomes a risk.
Why custom Next.js is faster (technically, but simply explained)
This is the part where most explanations turn into technical jargon. Let’s explain it differently.
When someone opens a Wix website, the browser has to download a large package of code that powers the entire platform. It includes the editor, the template system, and hundreds of features that your specific website may never use.
All of this loads before the visitor sees anything useful. Wix tries to optimize this, but physics cannot be avoided: more code means longer loading times.
Next.js works differently. During the build process, it can generate ready-made HTML pages in advance and send only the JavaScript required for that specific page to the browser.
No editor. No unnecessary platform features. No waiting for the platform. The page loads almost instantly because the server delivers exactly what is needed.
There is also static hosting. Next.js websites can run on a CDN (Content Delivery Network), meaning copies of your website are stored on servers around the world.
When someone from Trenčín opens your website, the data can come from a nearby location such as Frankfurt or Vienna rather than traveling from a US-based data center.
The result is measurable: Lighthouse scores of 95 to 100, Core Web Vitals in the green zone, loading times under one second.
Most importantly: the user does not wait.
Adrilex example: when Wix stops being enough
Adrilex originally ran on Wix. It was a functional website that served its purpose. But as the project grew, Wix started becoming a limitation.
The main problems were:
- Loading speed could not reach the level required for performance marketing. Every fraction of a second of delay affected Google Ads Quality Score and potentially increased click costs.
- SEO options were limited. When expanding content and targeting specific keywords, you need full technical SEO control, which Wix does not provide.
- Flexibility was limited. When the business needed specific changes that could not be built inside the editor, the answer was simply “not possible”.
The move to Next.js brought a Lighthouse score of 100 on desktop across all categories, with mobile achieving 94 performance and 100 in the remaining categories.
These are numbers that are extremely difficult to achieve with website builders.
One more thing is worth mentioning. Around the time the new website launched, Google Ads spend decreased by approximately 50%.
We are not claiming the new website alone caused this reduction, because that would be misleading. Multiple things changed at the same time.
However, a faster website with better landing page performance and improved Quality Score almost certainly contributed to more efficient ad spending.
It is a correlation, not proven causation, but the direction is clear.
When does moving to Next.js make sense, and when does it not?
Moving from Wix to Next.js is not universally the right decision. It is more expensive, takes longer, and not every company needs it.
Here is a simple framework.
Moving to Next.js makes sense when:
- Your website is a key revenue channel, not just a company presentation. Whether through direct sales, leads, or bookings.
- Loading speed directly affects your results. This is especially important for ecommerce websites or websites running paid advertising.
- You need functionality that cannot be built with a website builder: custom integrations, business logic, or specific user flows.
- You plan to grow long term, expand content, and know your future website requirements will exceed what you have today.
- You have already encountered a specific platform limitation, not just a feeling that “something better would be nice”.
Moving to Next.js does not make sense when:
- Your website is a simple company presentation with a few pages and will not change significantly.
- Your company is still in the early stages and every euro should go into the product or acquiring customers rather than the website.
- Your current website works, you are satisfied with it, and there are no specific limitations holding you back.
- “Because everyone says Next.js is better” is not a reason. It is a technology, not a religion.
If you are unsure, check our portfolio. We have several projects where we handled similar migrations.
Or take a look at our website development services. We can review your current website, tell you whether a migration is actually necessary, and explain what it would involve.
Sometimes the answer is: “Stay on Wix for now.”
And that is completely fine.
