Why businesses look for an alternative to WordPress
WordPress powers a large share of the web, and you can build good sites with it. The problems usually come from what gets stacked on top: the theme, the page builder and the plugin layer. Every addition loads more JavaScript and CSS on every page view, and every update is a potential conflict.
The result shows up in two places: the loading time and the maintenance invoice. Why many agencies keep selling that model anyway is something we have written about openly in the truth about why web agencies still sell WordPress. Here we stick to what can be measured.
The teardown: measure your WordPress site in ten minutes
You need no developer skills, just your site's address. Here is how:
- Open PageSpeed Insights, Google's free testing tool, and paste in your address. You can also run our performance test, which uses the same analysis engine and adds a security check.
- Look at the mobile result first. That is where most of your visitors are, and where WordPress sites usually lose the most.
- Note the three metrics under Core Web Vitals: LCP, INP and CLS. If there is field data from real visitors over the last 28 days, it carries more weight than the lab value.
- Scroll down to the improvement suggestions and note which files are singled out. If they live in /wp-content/plugins/ or /wp-content/themes/, you know where the weight comes from.
How to read the numbers
- LCP (Largest Contentful Paint): the time until the page's main content is visible. Google counts up to 2.5 seconds as passing.
- INP (Interaction to Next Paint): how quickly the page reacts when someone clicks. 200 milliseconds or less passes. Heavy plugin scripts are the most common culprit.
- CLS (Cumulative Layout Shift): how much the content jumps around while loading. Under 0.1 passes. Banners, cookie prompts and late-loading fonts push the value up.
Run the test on a typical WordPress site with a page builder and the improvement suggestions almost always point the same way: the theme, the plugin layer and the images. There is nothing strange about that. It is the price of the architecture.
Same test, different architecture: what Next.js does differently
A site built in Next.js has no plugin layer to load. Pages are pre-built so the server sends finished HTML, the code is split so a visitor only fetches what the current page needs, and images are compressed and resized automatically.
That does not mean Next.js sites are fast by magic in every situation. It means speed is the default, and you have to work to make them slow. In WordPress it is the other way around: there, optimization is its own project, often with yet another plugin.
If you want to see what that looks like in practice, run the same test on any Next.js site, including the one you are reading right now. We build all our websites in Next.js, and the numbers are open for anyone to check.
Optimize first, switch when you hit the ceiling
A slow WordPress site can often get faster without being replaced: compress the images, prune the plugins, review the caching. Do that first. It is the cheapest fix, and sometimes it is enough.
But there is a ceiling. As long as every page view has to pass through a theme, a page builder and a dozen plugins, there is a limit to how far optimization reaches, and the next update can put you back at square one. That ceiling is where a switch starts to pay for itself, especially if the site is central to how you win customers.
Switching without losing rankings
The most common reason to postpone a switch is the fear of losing SEO. Done right, you keep your rankings: addresses are kept or permanently redirected, the content comes along, and Google sees a faster site on the same domain. We have written a step-by-step guide to switching web agency without losing SEO.

In short
Do not look for a web agency that promises a better alternative to WordPress. Look for one that shows it. Run the test on your site today, run it on ours, and ask every agency you talk to for an explanation of the numbers.
