WordPress runs roughly 40% of the web. Which means a lot of agencies still build on it because they always have — not because it's the best fit for a modern small-business marketing site. Here's the real comparison.
What WordPress is good at. Blogging. Plugin ecosystem. CMS for non-technical editors. Multi-author editorial workflows. Sites with hundreds or thousands of pages. It earned its market share — for the right job, WordPress is genuinely good. (See our full Nexora vs WordPress comparison for the side-by-side.)
What WordPress is bad at. Speed. The average WordPress site loads in 2-5 seconds on mobile — a direct conversion penalty since 2024 when Core Web Vitals became a meaningful ranking signal. Speed is fixable on WordPress, but it takes specialized hosting (Kinsta, WP Engine) plus a build process most agencies don't bother with.
Maintenance burden. A WordPress site needs weekly plugin updates, monthly core updates, quarterly security audits, occasional emergency patches when a plugin gets compromised. If you're paying an agency $300-$500/month "maintenance" — that's mostly what they're doing (plus telling you they're doing more). Custom sites built on modern stacks don't have this overhead.
Security exposure. WordPress is the most-attacked CMS on the internet by orders of magnitude — because it has the largest install base. If you don't keep plugins updated, you'll get hacked. Most small-business WordPress sites we audit have at least one outdated plugin with a known vulnerability.
Performance ceiling on a small-business marketing site. WordPress out-of-the-box pulls in ~300-500KB of CSS, JavaScript, and database queries before any of your actual content loads. Custom sites built on Next.js, Astro, or 11ty ship 50-100KB total and load in under a second. For a site that's mostly informational + lead capture, that performance gap directly translates to higher conversion rates.
When custom wins. You're a service business that primarily uses the site to: rank locally, capture leads, and look professional. The number of pages is bounded (5-30). Content updates happen monthly, not daily. You don't need a CMS for non-technical editors. You want zero monthly maintenance. That's exactly what our packages ship — and the same pattern fits 80% of local service businesses.
When WordPress wins. You publish a high-volume blog (multiple posts per week). You have non-technical staff who need to edit content daily. You need a specific WordPress plugin with no equivalent on other platforms. You have an in-house WordPress developer already.
The actual decision rule. Look at how often your site content will change after launch:
- Monthly or less: Custom wins. Cheaper lifetime cost, faster site, no maintenance tax. - Weekly: It's a close call. WordPress's editor advantage starts to matter. - Daily: WordPress wins. The editor + plugin ecosystem pays off.
Most service businesses fall in the "monthly or less" bucket — and don't realize they're paying a maintenance premium on a platform they don't need. If you fit that profile, book a discovery call and we'll show you the alternative.
