Should you build your business website on WordPress, or have something custom-built? The honest answer depends on who you are — but not in the cop-out way most guides mean it. WordPress is the right call for a hobbyist, a blogger, or anyone who genuinely wants to run their own site as a hands-on project. For a business that just wants a fast, secure site that earns its keep and mostly leaves you alone, custom-built usually wins. The real question isn't which platform is better in the abstract. It's which one you'll still be glad you chose in two years.
WordPress is the default for a reason. It powers 41.9% of every website on the internet and 59.4% of all sites running a known content management system, according to W3Techs. When something is that dominant, "just use WordPress" stops feeling like a decision and starts feeling like gravity. But popular and right-for-you aren't the same thing, and the case for each comes down to a handful of trade-offs nobody prints on the sales page.
What "custom-built" actually means
The comparison gets muddied fast, so clear the terms first. WordPress is a content management system: a big, general-purpose engine you install, dress with a theme, and extend with plugins. A custom-built site is the opposite approach — code written for your business specifically, shipping only the features your site uses and nothing it doesn't.
A lot of what gets sold as "custom WordPress" is really a premium theme plus a page builder like Elementor or Divi, lightly reskinned. That's a legitimate way to work, but it's still WordPress underneath, carrying all the same trade-offs. Genuinely custom means the code was written for your site, not assembled from other people's parts. Hold on to that distinction — almost everything below flows from it.
Where WordPress genuinely wins
Let's be fair to the thing that runs nearly half the web. WordPress earns its share, and for the right owner it's the obvious choice.
- The ecosystem is enormous. The official directory alone lists more than 60,000 free plugins, so almost anything you can picture — bookings, memberships, forums, multilingual content — already exists as something you can install this afternoon.
- The entry cost is low. You can stand up a working site for the price of a theme and some hosting, without hiring anyone.
- Help is everywhere. With roughly two in five websites running it, any question you'll ever have is already answered in a forum somewhere, and you're never short of people who can work on it.
- You're not tied to one person. Because so many developers know WordPress, you can hand it off, swap freelancers, or take it over yourself.
If you want to run your own site as an ongoing hobby, or you're testing whether a business idea has legs before spending real money, WordPress is hard to beat. Nothing that follows is an argument that it's bad software. It's an argument that "most popular" and "right for a business that wants to be left alone" are two different things.
The plugin tax: security and upkeep
Here's what the convenience hides. Every plugin you install is someone else's code running on your site, and that code is the single biggest source of trouble in the WordPress world.
The numbers are stark. In 2024, Patchstack recorded 7,966 new vulnerabilities across the WordPress ecosystem — a 34% jump on the year before. Almost none of them were in WordPress itself: 96% sat in plugins, a sliver in themes, and just seven in the core software. More than four in ten could be exploited without anyone logging in at all.
Read that breakdown again, because it's the whole story. WordPress core is genuinely well looked after. The risk lives in the third-party add-ons you bolt on to make the platform do what you need — and a typical business site runs a stack of them, each on its own update cycle, each maintained by a different developer of unknown diligence. Patchstack also found that more than half the plugin authors it warned shipped no fix before the flaw went public.
Every plugin is a small bet that a stranger will keep maintaining their code as carefully as you'd maintain your own. A business site is a stack of those bets, all riding at once.
This is why a WordPress site carries ongoing care that never appears in the build quote. Someone has to watch for updates, apply them, confirm the update didn't break something else, and clean up when a plugin is abandoned. That's the recurring cost most businesses underestimate, and it scales with how many moving parts your site has. A custom site has fewer parts by design, so there's simply less to patch, less to break, and less to babysit.
Speed is a platform decision, not a setting
Performance follows the same logic, and it shows up in the data. The HTTP Archive's 2024 Web Almanac measured how many real sites pass Google's Core Web Vitals — the speed and stability thresholds Google folds into ranking. WordPress sites passed on mobile just 40% of the time. Squarespace managed 60%, Wix 57%, and Duda 73%. WordPress sat below even the 51% average across the whole web.
That isn't because WordPress can't be fast — a carefully tuned WordPress site absolutely can be. It's because the easy path makes it slow. Stack a theme, a page builder, and a dozen plugins, and each one ships its own CSS and JavaScript for the visitor's phone to download and run before the page is usable. The platform doesn't force the bloat. It just makes bloat the default, and defaults win.
A custom site starts from the other end. It ships the markup, styles, and scripts your pages actually need and nothing more, so it can run near a perfect score from the first commit. And speed isn't a vanity number — it's directly tied to conversions and search rankings. The platform you pick quietly sets the ceiling on both.
So which should you build?
Skip the feature checklist; it won't decide this. The choice tracks who you are and what you want your relationship with the site to be.
Build on WordPress if you want to run the site yourself, you'll genuinely keep up with the updates, your needs map cleanly onto existing plugins, and budget is the binding constraint. For a personal project, a content-heavy blog, or a quick test of an idea, it's the sensible default.
Build custom if the website is a business asset that needs to be fast, secure, and low-maintenance — something that works while you do, without turning into a part-time job or a standing security liability. If you'd rather never think about plugin updates again, that preference has a name, and the name is "custom."
The middle path most businesses actually want isn't a platform at all. It's a person — someone who designs and builds the site around your business, ships only what it needs, and then stands behind it.
That's the whole reason Bergh Software builds custom, performance-first sites instead of assembling them from plugins, and why one person designs, builds, and maintains each one — so there's no stack of strangers' code to babysit and no handoff where upkeep becomes nobody's job. If your current site is a WordPress install you've started to dread logging into, a rebuild is one of the most common projects we take on.
