WordPress – When is it Enough?

WordPress is good for:

  • Personal blogs – easy to use, many themes
  • Small business cards – quick deployment, low costs
  • Projects with limited budget – free CMS
  • Projects without performance requirements – low traffic

WordPress Problems for Businesses

1. Performance and Speed

  • Slow loading – WordPress loads many unnecessary things
  • Lack of optimization – themes and plugins slow down the site
  • Cache problems – requires additional plugins (WP Super Cache, W3 Total Cache)
  • Large page size – often 2-5 MB HTML

Custom Code:

  • Loads only what's needed
  • Optimization built-in from the start
  • Fast loading (often < 1s)
  • Small size (often < 100 KB HTML)

2. Security

  • Frequent updates – WordPress, themes, and plugins require constant updates
  • Security vulnerabilities – popular = more often attacked
  • Dependencies – one outdated plugin = risk
  • Lack of control – you don't know what all plugins do

Custom Code:

  • Full control over code
  • Less attack surface
  • Updates only when needed
  • Own security measures

3. Flexibility and Functionality

  • Theme limitations – hard to do something custom
  • Plugin dependency – each feature = another plugin
  • Plugin conflicts – different plugins can conflict
  • Customization limitations – hard to do something non-standard

Custom Code:

  • Full flexibility – you can do everything
  • Features tailored to needs
  • No conflicts – everything under control
  • One-time development cost

4. SEO and Optimization

  • Heavy themes – often poorly optimized
  • Code bloat – WordPress generates a lot of unnecessary HTML
  • Core Web Vitals problems – often poor Lighthouse scores
  • Structure limitations – hard to optimize for SEO

Custom Code:

  • Optimization from the start
  • Clean, semantic HTML
  • Excellent Lighthouse scores (often 100/100)
  • Full control over SEO structure

5. Long-term Costs

WordPress:

  • Hosting (often more expensive for WordPress)
  • Premium plugins (often $50-200/year each)
  • Premium themes ($50-100 one-time)
  • Updates and maintenance (time-consuming)
  • Performance problems (may require CDN, cache)

Custom Code:

  • Hosting (often cheaper)
  • No plugin costs
  • One-time development cost
  • Easier maintenance (fewer updates)
  • Better performance (fewer resources)

When to Choose Custom Code?

Choose custom code if:

  • You need a professional business website – image and performance matter
  • You have specific requirements – custom features, integrations
  • Speed matters – Core Web Vitals, SEO, conversions
  • You want full control – security, functionality, appearance
  • You plan to grow – easier to add new features in custom code

Example: WordPress vs Next.js (Custom Code)

WordPress:

  • Load time: 3-5 seconds
  • Lighthouse: 60-80/100
  • HTML size: 2-5 MB
  • Plugins: 10-20 (often conflict)
  • Updates: monthly (WordPress + plugins)

Next.js (Custom Code):

  • Load time: < 1 second
  • Lighthouse: 95-100/100
  • HTML size: < 100 KB
  • Dependencies: only needed
  • Updates: when needed

Summary

WordPress is good for simple projects, but for professional business websites, custom code is better. It gives full control, better performance, security, and flexibility. The one-time development cost pays off in long-term savings and better results.
