When planning a new company website, the question of technology comes up early. Two names appear especially often: WordPress, the most widely used content management system, and Next.js, a modern framework for web applications. Both are good tools, but for different requirements. This article compares them and helps you decide.
What is WordPress?
WordPress is a content management system (CMS): software that lets you maintain content through an interface without programming. It is open source and licensed under the GPL, so there are no licence fees. According to W3Techs, around 39 percent of all websites use WordPress, and among websites with a known CMS the figure is 58 percent (as of November 2026).
WordPress's strength is its ecosystem: thousands of themes (design templates) and plugins (extensions) cover almost every need, from contact forms to an online shop with WooCommerce.
What is Next.js?
Next.js is an open-source framework based on React, a widely used JavaScript library for user interfaces. It is developed primarily by the company Vercel. Next.js is not a ready-made CMS but a toolkit for developers to build websites and web applications from code.
For search engine optimisation and load times, Next.js has an important advantage: pages can be generated in advance on the server. Visitors and search engines receive finished HTML instead of waiting for content to load via JavaScript. Content is usually managed in a so-called headless CMS, an editorial system that only manages content and delivers it to the website through an API.
A Next.js website can be run with specialised hosting providers, on your own servers or, if no server-side features are needed, even as a plain set of static files. This gives you flexibility regarding hosting location and data protection.
The comparison at a glance
| Criterion | WordPress | Next.js |
|---|---|---|
| Type | ready-made CMS | framework for custom development |
| Content editing | built in, familiar to many editors | via a separate headless CMS |
| Getting started | fast, many ready-made themes | custom development required |
| Extensions | large choice of plugins | features are coded or connected via services |
| Load time | good results possible, depends heavily on theme and plugins | very good results achievable through pre-rendered pages |
| Security | regular updates of core, themes and plugins required | smaller attack surface, but dependencies still need maintenance |
| Custom features | via plugins or custom PHP development | very flexible, ideal for app-like features |
| Developer involvement day to day | low for content editing | higher for changes to structure and layout |
When WordPress is the right choice
WordPress is strong when your team wants to manage content itself without developers and your requirements fit existing solutions well.
- Company websites with a blog and service pages that are regularly updated by marketing or management
- Online shops with WooCommerce, if you want to manage products, orders and payments in one system
- Limited budgets, because existing themes and plugins save development time
- Many stakeholders who already have experience with WordPress
The price for this is maintenance. The WordPress core, themes and plugins need regular updates. Every plugin is additional code that may contain security vulnerabilities or slow the site down. If you use WordPress, keep plugins to a minimum and plan firmly for updates, backups and monitoring.
When Next.js is the better choice
Next.js shows its strengths when performance, design freedom or custom features are the priority.
- Websites with demanding load-time targets, for example when Core Web Vitals (Google's metrics for loading speed, responsiveness and visual stability) are an important goal
- Custom design without the limits of a theme
- App-like features such as customer portals, configurators, calculators or booking flows
- Integrating many data sources, for example from CRM, product databases and a headless CMS
- Multilingual websites with a clean structure
In return, changes to structure and layout usually require developers. Day-to-day content editing through the headless CMS still works without programming skills.
The middle ground: headless WordPress
The two worlds can be combined. With "headless WordPress", WordPress serves only as the editorial system, and Next.js handles the presentation of the website. Your team works in a familiar interface, while visitors get a fast, custom-designed site.
This approach is, however, more complex than a classic WordPress website. Some plugins that rely on the front end no longer work as usual, and two systems have to be operated. It is mainly worthwhile when a lot of content already lives in WordPress or the editorial team is firmly used to it.
Cost: what to look out for
A fair cost comparison considers launch and operation over several years:
- WordPress: often a lower entry cost, but ongoing costs for updates, maintenance, premium plugins and hosting
- Next.js: usually higher development effort at the start, often less maintenance thanks to the absence of a plugin landscape, plus costs for hosting and the headless CMS
Which model is cheaper depends on scope, how often things change and your internal resources.
Decision guide: your questions
- Who maintains the content, and how often? Frequent editing by non-technical staff points to WordPress or a good headless CMS.
- Do you need an online shop? For classic shops, WooCommerce is often the more direct route.
- How important are load times and Core Web Vitals? The more important, the more likely Next.js or a very lean WordPress build.
- Are you planning interactive features or portals? Then Next.js is usually more flexible.
- Who takes care of updates and security? Assign clear responsibilities for this with either system.
- Is there existing content to migrate? Assess the migration effort early.
