“Build it on WordPress or write it from scratch?” — a question with plenty of biased answers on both sides. WordPress advocates call custom code “expensive and unnecessary”; developers call WordPress “slow and insecure”. The truth depends on the task, and this article gives you the questions to make the choice yourself.

In short: what is what

WordPress is a ready content management system: an admin panel, themes and thousands of plugins. You (or a developer) pick a theme, add plugins and fill in content. A large share of the world’s websites runs on it.

A custom website is code written from scratch for your task — HTML/CSS/JavaScript, React where needed, and its own backend. A content management system appears only if you genuinely need one, and exactly as you need it.

There is a middle option — a statically built site generated by a build system and published as plain files (like this site). It gives the speed and security of custom code, but content changes need a developer.

When WordPress makes sense

  • You or your team change text, news and pages regularly and do not want to wait for a developer.
  • You need standard functions: blog, gallery, forms, a WooCommerce store — all ready and proven.
  • The budget is limited and adapting a ready theme is enough.
  • You want another developer to be able to continue the site in future — WordPress specialists are everywhere.

One condition: someone must keep it updated. A WordPress site nobody looks at for a year is a security risk. More on the WordPress development page.

When custom code makes sense

  • The site rarely changes and speed, security and minimal maintenance matter most — a landing page, a business-card site, a company site with a few pages.
  • Business logic is non-standard: calculators, complex booking rules, personal accounts, integrations with a warehouse or CRM.
  • Traffic or performance requirements are high and a ready system’s overhead gets in the way.
  • The product itself is the business (platform, service, app) and its growth does not fit a ready system’s limits.

For those cases: website development and custom software.

Common mistakes

  • “WordPress is free, so it is cheap.” The system is free, but a quality theme, plugin licences, hosting and regular maintenance over the years often cost more than a custom static site.
  • “Custom code is secure by itself.” No — badly written backend code is less secure than any WordPress. Security is an approach, not a technology.
  • “A plugin will fix everything.” Every plugin adds load and risk. A site built from 40 plugins costs more to maintain than one well-configured system.
  • “We will migrate later.” Moving from WordPress to custom (or back) is a new project. The right choice at the start saves both sides.

How to decide

Answer three questions: (1) How often, and who, will change content? (2) Do you need a function that is not on the standard list? (3) Who will look after the site after launch? If the answers are “often, ourselves / no / nobody in particular” — WordPress. If “rarely / yes / a developer or maintenance” — custom. If in between, send us the task — we will decide together on the concrete need, without bias towards a technology.
