WordPress vs Custom Website: Flexibility, Cost and Maintenance (France)

Les planchers Duyuz (Launch €590, SEO Growth €399/mois, Shopify dès €1490, AI €390+€89/mois) ancrent les arbitrages freelance/agence et SEO/Ads sans loyer parisien. WordPress suits teams that need flexible pages and a familiar CMS. Lightweight custom builds suit focused service sites that prioritise speed and minimal plugin risk. Neither is morally superior — fit beats fashion.

Best use case

When each option fits

WordPress

Marketing teams editing many pages, blog/resources hubs, and plugin-driven features you actually need.

Custom / lightweight build

Tight service sites with stable IA where performance and simplicity matter more than CMS flexibility.

Cost & speed

What it costs and how fast it moves

WordPress — Cost

Often similar build floors to Business packages; ongoing care is important (updates/security).

Speed

Fast to extend pages once set up; can slow if overloaded with plugins.

Custom / lightweight build — Cost

Duyuz Launch/Business packages from €590 / €990 campaign for focused sites — maintenance still required, just differently.

Speed

Fast for fixed scopes; slower if you later need a full CMS.

Plugin debt and page-builder bloat are the hidden WordPress costs; rebuilds are the hidden custom cost when editors need a CMS later.

Advantages and limitations

Both sides have trade-offs — we recommend based on fit.

WordPress — Advantages

  • Editor familiarity✓
  • Huge ecosystem✓
  • Good for content-heavy sites✓

Limitations

  • Update/security discipline required✓
  • Easy to accumulate fragile plugins✓

Custom / lightweight build — Advantages

  • Lean performance possible✓
  • Fewer moving parts✓
  • Clearer security surface when small✓

Limitations

  • Less ideal for non-dev editors at scale✓
  • Feature creep forces platform rethink✓
When to combine

Using both — deliberately

Use WordPress when editorial velocity is real; use custom when the site is a sharp sales tool with rare edits — or a headless setup when justified (scoped separately).

How to decide

Choose WordPress for content operations. Choose custom for focused conversion sites. Revisit if the team’s editing needs change.

Local decision factors in France

  • Paris/Lyon agency density raises Ads CPC and Local SEO competition for services✓
  • Buyers expect devis écrits with hors-périmètre — freelance vs agence hinges on that discipline✓
  • RGPD and mentions légales are non-negotiable launch gates often missing in cheap builds✓
  • “Sur devis” opacity loses to published planchers when comparing SEO, Ads and web packages✓

FAQ

Is WordPress outdated?

No. Poorly maintained WordPress is the problem — not the platform itself.

Are custom sites always faster?

They can be when kept lean. A bloated custom app is not magically fast.

Can Duyuz do both?

Yes. We pick based on editorial needs and maintenance reality.

What about Webflow or other builders?

Possible when they fit the team. We do not chase tools for their own sake.

Refonte ou nouveau site ?

Refonte dès €890 si l’équité URL et les avis comptent. Nouveau build si l’architecture et le CMS sont trop endettés pour un sauvetage propre.

SEO ou SEO local d’abord ?

SEO local dès €249/mois si Maps et intention de proximité dominent. SEO plus large dès €399/mois pour des termes nationaux / contenu.
