Every few months, a client comes to us having been told by someone — a colleague, a consultant, a well-meaning friend — that WordPress is "the obvious choice" for their new website. Sometimes it is. More often, it isn't. And increasingly, the gap between what WordPress can do well and what it does poorly has become large enough that the choice matters a lot more than it used to.
We've been building with Wagtail since 2015. We've also built, migrated, and maintained WordPress sites across that same period. This comparison is based on real project experience, not benchmarks manufactured for a blog post.
Content modelling: the most important difference
The biggest practical difference between Wagtail and WordPress isn't the technology stack — it's how each platform thinks about structured content.
WordPress's fundamental model is: posts have a title, a body, some metadata, and some custom fields. Gutenberg blocks improved things significantly, but the underlying data model is still a flat blob of serialised block data attached to a post. Building genuinely complex, structured content — say, an event with multiple speakers, each with their own bio, photo, and affiliation — requires plugins and workarounds that accumulate technical debt quickly.
Wagtail's StreamField solves this differently. You define blocks in Python — typed, validated, composable — and Wagtail serialises them cleanly to JSON. Each block type is a first-class Django model. The result is content that can be queried, filtered, and rendered reliably across multiple output formats.
classEventPage(Page): speakers = StreamField([ ('speaker', StructBlock([ ('name', CharBlock()), ('bio', RichTextBlock()), ('photo', ImageChooserBlock()), ('talk_title', CharBlock()), ])) ]) venue = models.ForeignKey('locations.Venue', on_delete=models.PROTECT) start_time = models.DateTimeField() ticket_url = models.URLField(blank=True)
This is explicit, type-safe, and queryable. There's no equivalent in WordPress without a significant plugin dependency like ACF Pro or Pods.
Security track record
WordPress powers roughly 43% of the web. That makes it the most attacked content management system by a significant margin. The core team does solid security work, but the plugin ecosystem is the real risk — thousands of plugins with varying levels of maintenance, hundreds of known CVEs at any given time, and the perpetual question of whether your hosting provider is applying patches promptly.
Wagtail inherits Django's security model, which is genuinely excellent. Django's ORM prevents SQL injection by design. CSRF protection is on by default. The template engine auto-escapes output. The admin interface (which is Wagtail's editorial UI) isn't exposed to the public internet in the way WordPress's /wp-admin is.
The attack surface of a Wagtail site is meaningfully smaller. There's no plugin ecosystem to worry about, and the dependency graph — Python packages — is auditable and manageable with tools like pip-audit.
Editorial experience
WordPress wins on familiarity. It has 20 years of mindshare, and most marketing professionals have used it. The Gutenberg editor is genuinely good for blog-style content and many editors find it intuitive.
Wagtail's editorial interface is also excellent, but in a different way. It's cleaner, faster, and more focused. The panel system lets you design the editor interface to match the actual content model — related pages inline, field ordering that reflects editorial workflow, contextual help text where needed. Editors of complex Wagtail sites consistently report that it's easier to use than WordPress for anything beyond simple blog posts.
Wagtail also has some features that WordPress struggles to match: per-page workflow with moderation, full revision history with diff view, scheduled publishing at the page level, and proper multi-site management from a single admin.
Performance
A tuned WordPress installation can be fast, but it requires tuning — object caching (usually Redis or Memcached via a plugin), a CDN, a page caching plugin like WP Rocket, and careful management of database queries. A default WordPress install on shared hosting is not fast.
Wagtail sits on Django, which gives you proper server-side Python caching, database connection pooling, and a straightforward path to serving static assets via WhiteNoise or a CDN. Wagtail has built-in cache invalidation hooks, so your cache is always coherent with your published content.
For high-traffic or performance-sensitive sites, Wagtail is a better starting point. The headless mode — Wagtail as an API feeding a Next.js frontend with ISR — produces page loads that WordPress simply can't match without a completely different architecture.
Hosting and operations
WordPress hosting is a solved problem. Managed WordPress hosting from providers like Kinsta, WP Engine, or Cloudways means you don't have to think about server configuration. That's a real advantage for teams without DevOps capability.
Wagtail requires a Python hosting environment — which is straightforward on platforms like Railway, Fly.io, or Heroku, but requires more configuration than managed WordPress. For our clients, we typically deploy on Fly.io or AWS ECS with a PostgreSQL database and S3 for media. It's not complicated, but it is more involved than a one-click WordPress install.
When we recommend WordPress
We're honest with clients when WordPress is the right choice. These situations are:
- A simple blog or brochure site where the content is genuinely just posts and pages
- The team has existing WordPress expertise and no Python developers
- Budget is very constrained and managed WordPress hosting removes operational burden
- The project timeline is extremely short and WordPress's out-of-the-box CMS features are sufficient
- There's an existing WordPress ecosystem (themes, e-commerce with WooCommerce) that would be expensive to rebuild
Our recommendation
If your project has genuinely structured content, complex editorial workflows, performance requirements, security sensitivity, or a development team comfortable with Python, Wagtail is the superior choice in almost every dimension.
If your project is a marketing site with simple blog posts, a small team, a tight budget, and no Python developers, WordPress is probably fine — and we'll tell you that.
The worst outcome is spending engineering time fighting the wrong tool. We've seen organisations rebuild their WordPress sites in Wagtail after two years of patch-related pain, plugin conflicts, and performance struggles. We've also seen organisations build overly complex Wagtail sites when a well-configured WordPress would have done the job.
The right CMS is the one that fits your content, your team, and your trajectory. We're happy to talk through which one that is for your specific situation.
