Migrating from WordPress to Next.js: When is it worth it and what to expect?

A comparison of WordPress and Next.js for business owners. Find out when it's time for an architecture change for better speed and SEO.

WordPress powers over 40% of the internet. It's a great tool if you're just starting out or need a simple blog. But what if you're outgrowing it? What if your site takes forever to load, the administration crashes under the weight of plugins, and your SEO results are stagnating?

Over the last year, more and more of my clients have been moving to Next.js. Let's be honest about when this step is a high-return investment and when it's better to stick with the classic.

Why does WordPress (sometimes) stop being enough?

WordPress suffers from one ailment: technical bloat. Every additional plugin you add for SEO, speed, or a contact form adds lines of code that the browser has to process. The result is:

Slow loading: Poor scores in Core Web Vitals (and thus lower rankings on Google).
Security risks: The need for constant plugin updates to eliminate vulnerabilities.
Limited creativity: You are bound by a template or visual builders that generate inefficient code.

Next.js: The Formula 1 of websites

Next.js (built on React) works fundamentally differently. Instead of the page being generated on the server every time someone clicks on it (like with WP), Next.js can prepare it in advance or serve it lightning-fast thanks to static generation.

What do you gain by migrating?

Brutal speed: Pages switch instantly. No "white screen" while loading.
Top-notch SEO: Google loves websites that are technically clean and lightning-fast.
Security: There is no public database directly connected to the frontend that someone could attack.
Scalability: The website can handle thousands of people at once without the server breaking a sweat.

When is the migration worth it?

I won't lie to you - switching to Next.js is more demanding than installing a ready-made template. It pays off especially in these cases:

You have high traffic: Every second of loading costs you conversions and real money.
You are building a unique product: You need interactive elements, calculators, or connections to external APIs and AI models.
You are looking for a "Headless" solution: You want a modern frontend in Next.js, but continue managing content in a simple interface (e.g., Contentful, Sanity, or even WordPress via API).

What to expect during the process?

Migration isn't just about "copy-pasting" texts. It's a strategic process that involves:

Content audit: Reviewing what needs to be kept and what is already unnecessary.
Architecture design: How to best connect the frontend with your data.
Redirects (301): The crucial technical part so your old Google links don't stop working.
Performance boost: Immediately after deployment, you will see "green numbers" in Google Search Console.

Conclusion: Is it time for a change?

If you feel that WordPress is holding back your growth, Next.js is a logical step forward. It's a transition from a "one-size-fits-all solution" to a custom solution that will grow with you for years to come.

Vibe Coding: A Development Revolution or a Security Nightmare?

Radek Hřebeček — Tue, 24 Mar 2026 10:55:34 +0000

Programming in 2026 is no longer about syntax, but about the "vibe". But who checks the security of the code that AI wrote for you?

The term "Vibe Coding" has taken over social media. It's that fascinating state where you simply describe your ideas in a chat, and an AI (like Cursor or Replit) builds entire blocks of code right before your eyes. You no longer need to memorize documentation; you just need a vision and the right "vibe".

But there's a catch that enthusiastic videos on YouTube or TikTok don't mention: Who guarantees that the code is secure?

Speed vs. Security

AI models are trained on massive amounts of data, which also include outdated practices and bugs. When you ask an AI to create a login form, it does it in 5 seconds. But do you ask yourself these questions?

Are passwords properly hashed using modern algorithms?
Did the AI sanitize inputs against SQL injection, or did it just blindly connect to the database?
Are your secret API keys leaking directly into the LLM model's history via your prompts?

The Invisible Bug Problem

The biggest danger of vibe coding for the general public (non-programmers) is that the application looks like it works. Everything moves, buttons click, data is saved.

However, a security hole isn't visible in the UI. It's hidden deep within the logic the AI generated. If the creator doesn't understand what the model "spat out", they are creating a black box that can explode at any moment under the barrage of the first bot that scans the web.

How to "Vibe Code" and Not Get Burned?

Vibe coding isn't bad—it's an incredible productivity boost. But you have to approach it with a developer's respect:

The AI is the junior, you are the senior: Never push code to production without trying to understand it. Ask the AI: "How is security handled in this code?"
Use security linters: Even if you aren't writing the code, run it through tools like Snyk or SonarCloud. They will uncover vulnerabilities that your "vibe" overlooked.
The principle of least privilege: Don't give the AI application access to your entire server. If it makes a mistake in the code, the damage should be minimized.

The Future Belongs to the Responsible

Vibe coding opens the door to the tech world for millions of people. That is great news. But with great tools comes great responsibility. The real winner in the AI era won't be the one who generates an application the fastest, but the one who can build a solution that is fast, functional, and above all, secure.

Do you want to have the code of your AI application checked before releasing it to the world? Reach out to me, I will perform an audit of your architecture and ensure your project is built on solid foundations.
