Should I Use WordPress or Custom Development? [Platform Comparison]

Use WordPress if you need a content-managed website on a budget and want to update it yourself. Choose custom development when you need unique functionality, maximum performance, or a web application that off-the-shelf platforms can't deliver.

This isn't a "one is better" debate. They solve different problems. The right choice depends on what your business actually needs, not what's trendy.

WordPress powers over 40% of all websites globally. There's a reason for that:

• Cost-effective. A WordPress site in NZ typically costs $3,000–$10,000 — significantly less than custom development.
• Fast to build. Themes and plugins speed up development. A solid WordPress business site can launch in 4–6 weeks.
• Easy to manage. Non-technical people can update content, add blog posts, and manage pages without touching code.
• Huge ecosystem. Over 59,000 plugins for almost any functionality you can imagine — SEO (like Yoast or Rank Math), forms, bookings, e-commerce via WooCommerce, you name it.
• SEO-friendly. With the right setup, WordPress sites rank well. Most SEO professionals are comfortable working with it.

Being honest about the limitations:

• Performance ceiling. Plugin-heavy WordPress sites can become slow. Every plugin adds code that needs to load, and not all plugins are well-built.
• Security maintenance. WordPress is the most targeted CMS for attacks because of its market share. Regular updates of core, themes, and plugins are non-negotiable. Tools like Wordfence help, but require ongoing attention.
• Customisation limits. You can push WordPress far, but at some point you're fighting the platform instead of building on it. Complex custom features often cost more to implement in WordPress than from scratch.
• Plugin dependency. If a key plugin gets abandoned or has a security vulnerability, you're exposed. This happens more often than people realise.

Custom-built sites ($10,000–$30,000+ in NZ) make sense when:

• You need unique functionality. User portals, custom workflows, booking engines, internal tools — if it doesn't exist as a plugin, custom is the way.
• Performance is critical. Custom code means no bloat. Frameworks like Next.js or React let you control every line, which means faster load times and better Core Web Vitals scores.
• You're building a product, not a brochure. SaaS platforms, marketplaces, and web applications need custom architecture.
• Security requirements are high. Custom-built means a smaller attack surface. No shared codebase with millions of other sites.
• Long-term scalability matters. Custom code scales with your business. You're not limited by what a plugin ecosystem can support.
