Why choose Wagtail as a CMS rather than WordPress?
When it comes to choosing a Content Management System (CMS), it is essential to prioritise a solution that is performant, secure, and scalable. At KERN IT, we strongly recommend Wagtail, an open-source CMS based on Django, as it outperforms WordPress in several key areas. Here is why Wagtail could be the ideal solution for your web project.
The Key Advantages of Wagtail
1. Modern and high-performance architecture
Wagtail is built on Django, a Python framework renowned for its strength and performance. Unlike traditional solutions, it offers a lightweight and optimised foundation, ensuring fast loading times, even for large websites. Its integrated caching system further improves performance, reducing server response time.
2. Reinforced security
Security is a priority for Wagtail. Thanks to Django's built-in protections, your website is safeguarded against common attacks such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). Moreover, the limited need for external plugins reduces the risk of vulnerabilities. Security updates are also handled centrally, simplifying maintenance.
3. Complete Customisation
Wagtail provides complete flexibility for creating complex websites. Developers can design custom data structures and choose the most suitable frontend technologies. This ensures a website that is perfectly aligned with your needs, with no compromises. Its intuitive page editor also allows non-technical teams to manage content with ease.
4. Integrated Artificial Intelligence
With Wagtail AI, optimise your content management using tools based on artificial intelligence. This functionality helps you to automate certain editorial tasks, improve search engine optimisation (SEO), and make your website even more performant. For example, the AI can suggest improvements for SEO content, generate automatic descriptions, and propose stylistic corrections.
5. Scalability Guaranteed
Unlike many traditional CMS platforms, Wagtail is designed to evolve with your business. Whether you manage a small website or a complex platform, its modular structure guarantees optimal performance, even during periods of heavy traffic increase. It also supports deployment on cloud environments, simplifying scalability.
6. The favourite choice among associations and organisations
Prestigious institutions such as Google, NASA, the British NHS, and numerous NGOs use Wagtail to manage their digital platforms. Its proven reliability makes it the ideal solution for ambitious projects. Non-profit associations particularly appreciate its flexibility and low operating costs.
7. Optimised User Experience
Wagtail’s administration interface is designed to offer a fluid and intuitive user experience. Editorial teams can manage content with minimal training, thanks to a clean dashboard, a real-time preview function, and a customisable publishing workflow.

The limitations of WordPress
Although WordPress is the most widely used CMS, it has several limitations for projects requiring strong performance and customisation:
- Reliance on plugins: Adding features often requires extensions, which slows down the website and increases the risk of vulnerabilities.
- Performance issues: Over time, the accumulation of plugins slows the site down.
- Poor security: Outdated extensions can expose your website to attacks.
- Limited customisation: Adapting a WordPress website to specific needs can require complex workarounds.
- Recent litigations: The recent dispute between Automattic, the parent company of WordPress, and WP Engine, highlights the fragility of the WordPress ecosystem. This conflict concerns the intellectual property of premium plugins, which could affect the continuity of services for users who rely on these extensions.
