WordPress vs custom site: when each one makes sense (2026)
An honest comparison between WordPress and a custom site built on a modern stack (Next.js, Astro). When each one makes sense for a small Argentine business, and the hidden costs nobody tells you about.
"WordPress or something custom?" is probably the technical decision small businesses postpone the most when they want a new site. And it's understandable: WordPress is still the best known option, but it's also the one that costs the most when things get serious. Let's take the comparison apart honestly.
When WordPress is fine (genuinely)
We're not going to bash it for free. WordPress has cases where it's the right choice:
- Active blog with multiple authors who publish constantly and need a friendly visual editor.
- Large, dynamic catalog (more than 200 products) where the owner updates prices and stock every day from their phone.
- Zero or near zero budget to get started and you're going to manage everything yourself, knowing you'll lose hours dealing with plugins.
- You need specific functionality that already exists as a mature plugin (complex memberships, forums, e-learning with an LMS) and you don't want to build it.
If you fall into one of these cases, WordPress can be a reasonable decision.
When it's NOT fine (and almost nobody says it)
For most small Argentine businesses that need a landing page or an institutional site, WordPress is the worst decision over 12 months. For these reasons:
Performance is a structural problem
WordPress loads PHP, a database, dozens of scripts, and plugin CSS on every request. Even with caching, the average site loads in 3-6 seconds on mobile with average connectivity. Google penalizes that in ranking, the Core Web Vitals (LCP, INP, CLS) are metrics that feed into the search algorithm, and a WordPress without extreme optimization rarely passes them.
A custom site on a modern stack (Next.js, Astro) loads in under 1.5 seconds with no effort, because it serves static HTML from a CDN.
Maintenance is a constant drip
WordPress requires constantly updating the core, the plugins, and the theme. If you don't, it breaks or gets hacked. If you do, something stops working and you have to fix it. The maintenance cost of an active WordPress is usually between $20,000 and $50,000 ARS per month (someone keeping an eye on it, backups, patches, resolving plugin conflicts).
A well built custom site has no plugins to update. If you want to change some text, you change it yourself from a minimal panel (or you ask us for the change and we deploy it within hours).
Security: WordPress is the web's #1 target
More than 40% of sites on the internet are WordPress. It's the main target of automated attacks. Most of the small business hacks we see are WordPress sites with outdated plugins or pirated themes. Cleaning them up costs more than rebuilding the site.
Total cost over 12 months
An honest comparison for a typical landing page / institutional site:
| Item | WordPress (DIY or freelance) | Custom site (agency) |
|---|---|---|
| Upfront cost | $0 – $300,000 ARS | $200,000 – $500,000 ARS |
| Annual hosting + domain | $80,000 – $200,000 ARS | $30,000 ARS (Vercel free + domain) |
| Monthly maintenance | $20,000 – $50,000 ARS | $0 – $25,000 ARS (optional) |
| Premium plugins/themes | $50,000 – $150,000 ARS | $0 |
| Total cost year 1 | $370,000 – $1,250,000 ARS | $230,000 – $830,000 ARS |
And that's without counting the cost of the time you lose fighting with WordPress.
What a "custom site" is in 2026
It's not the same as 10 years ago. "Custom" today doesn't mean a programmer writes HTML from scratch, it means using a modern framework (Next.js, Astro) on cloud infrastructure (Vercel, Cloudflare) to build a static or near static site, optimized down to the millimeter.
Concrete features:
- Static HTML served from a global CDN. Loads fast anywhere in the country, even on a bad connection.
- Automatically optimized images (WebP, AVIF, lazy loading, explicit dimensions).
- Technical SEO out of the box. Correct meta tags, automatic sitemap, structured data (JSON-LD), Open Graph, Twitter Cards.
- No database to maintain (in most cases). Fewer things that can break.
- A minimal panel if you need one. For text or products, you can have an editor (with MDX, Sanity, headless Strapi) or just ask us for the changes directly.
- Practically free hosting while traffic stays low (the Vercel free tier covers most small businesses).
Head to head comparison
Performance
- WordPress: typical 3-6s LCP, requires aggressive caching.
- Custom: under 1.5s LCP with no effort.
SEO
- WordPress: Yoast/RankMath plugin, constant manual optimization.
- Custom: technical SEO included, correct structured data from day one.
Maintenance
- WordPress: permanent updates, risk of breaking.
- Custom: almost none unless features are added.
Cost over 12 months
- WordPress: cheaper upfront, more expensive over the year.
- Custom: more expensive upfront, cheaper over time.
Security
- WordPress: a permanent target, requires attention.
- Custom: minimal attack surface.
Content flexibility
- WordPress: friendly visual editor.
- Custom: depends, from "just ask us for the change" to a full headless CMS.
Unique design
- WordPress: themes, they all end up looking alike.
- Custom: your own design, real identity.
When to choose each one
Choose WordPress if:
- You're going to publish 4+ blog posts per month for years.
- Your model is e-commerce with a large, rotating catalog (although WooCommerce has its own problems, Shopify is usually a better option).
- You have zero budget and you're going to maintain it yourself.
- You need a specific plugin you don't want to build.
Choose custom if:
- You want a landing page or institutional site that loads fast and ranks well.
- You care about security and don't want to keep up with patches.
- You're thinking 12+ months out (not just the upfront cost).
- You want a design that doesn't look like a template.
For landing pages and institutional sites, the balance almost always tips toward "custom." For large blogs with many authors, WordPress still makes sense.
