The rise of WordPress and webflow: key shifts reshaping the CMS landscape

The CMS market has never been more competitive — or more interesting. For the better part of a decade, WordPress held an almost unchallenged position as the default choice for everything from personal blogs to enterprise marketing sites. Then Webflow arrived, matured, and began pulling a specific and valuable segment of the market toward a fundamentally different model. Today, these two platforms coexist in a way that tells us a great deal about where web development is heading, what clients actually need, and how agencies need to position themselves to deliver real value.

This is not a story about one platform beating another. It is a story about market segmentation, evolving buyer expectations, and the technical decisions that separate projects that scale from projects that stall.

Why WordPress Still Dominates — and Where It Is Evolving

WordPress powers approximately 43% of all websites on the internet. That number is frequently cited, frequently questioned, and ultimately still remarkable. It reflects not just historical momentum but genuine utility: a platform that has proven it can handle everything from a five-page brochure site to a global multisite network serving millions of daily visitors.

What has changed is how WordPress is being used at the professional level, and what separates serious WordPress development from the commodity work that has given the platform a mixed reputation.

The Gutenberg Maturity Curve

The block editor — Gutenberg — spent its first few years being widely disliked. Developers who had built workflows around the Classic Editor or Advanced Custom Fields resisted the change. Clients found the interface confusing. The ecosystem of plugins that extended Gutenberg was immature.

That picture has shifted substantially. Full Site Editing (FSE) and block themes now offer a genuinely powerful model for building editable, structured layouts without coupling design decisions to PHP templates. The theme.json system gives developers fine-grained control over typography, spacing, color palettes, and layout constraints — all exposed to the editor in a way that prevents clients from breaking their own sites.

At werun.dev, our WordPress work reflects this maturity. We build custom Gutenberg blocks and patterns that give editorial teams real flexibility while enforcing design consistency. A block built properly — with block.json registration, server-side rendering where appropriate, and InspectorControls that expose only the options that make sense — is a fundamentally better content tool than a shortcode or a page builder widget.

Plugin Development as a Product Discipline

One of the clearest markers of professional WordPress development is how plugins are built. The WordPress Plugin API — hooks, filters, the REST API, capability checks, nonces, sanitization and escaping — exists for a reason. It provides a contract between your code and the WordPress core that makes upgrades survivable and security audits tractable.

The agencies and freelancers who treat plugin development as a product discipline — shipping with documentation, maintaining changelogs, implementing auto-update systems via GitHub releases — are delivering something categorically different from the person who drops a few functions into functions.php and calls it done.

Our plugin development practice is built around these standards. Every custom plugin we ship includes:

• Proper use of WordPress APIs: Settings API, Options API, WP_Query, WP_REST_Controller
• Nonce verification on all form submissions and AJAX requests
• Capability checks before any privileged operation
• Sanitization on input, escaping on output — always
• A GitHub-powered auto-update system so client sites stay current without manual intervention
• Documentation that a developer who has never seen the codebase can follow

WooCommerce as an Enterprise Platform

WooCommerce has matured in a direction that surprises people who dismissed it as a simple shopping cart plugin. Complex B2B wholesale stores, subscription billing systems, custom product configurators, and ERP integrations are all live in production on WooCommerce — built by teams who understand the extension points the platform provides.

The key is treating WooCommerce as a framework rather than a finished product. Custom product types, pricing rules built on the woocommerce_get_price filter chain, checkout field logic, and fulfillment integrations via the REST API give you a commerce platform that can match almost any business requirement. The constraint is almost always developer knowledge, not platform capability.

This is where werun.dev's WooCommerce practice focuses: complex builds that require understanding the internals, not template customization.

Webflow's Ascent and the Design-Development Convergence

Webflow occupies a different position in the market, and understanding that position clearly is more useful than the tired debate about whether it is a "real" development tool.

Webflow is a visual development environment that generates clean, semantic HTML and CSS. It is not a drag-and-drop website builder in the Wix sense. The distinction matters because Webflow's output is production-quality markup — and because the platform's CMS, API, and extensibility model are sophisticated enough to support serious business requirements.

The segment of the market that has moved toward Webflow is identifiable: design-led marketing teams, agencies with strong visual design practices, and companies that need their marketing site to move fast without a developer in the loop for every content update.

CMS Architecture as a First-Class Concern

The most common failure mode in Webflow projects is treating the CMS as an afterthought. A site built with poorly structured CMS Collections — or with content that should be dynamic hard-coded into static pages — creates editorial debt that compounds over time. Content editors can't do their jobs. The site can't scale. The agency gets blamed.

Building Webflow CMS architecture properly means thinking about the data model before touching the Designer. Which content types need Collections? What relationships exist between them — and how do you model those relationships within Webflow's reference field constraints? How does the URL structure of Collection pages serve both SEO and editorial workflow?

At werun.dev, we treat CMS architecture as a design problem that precedes visual design. The structure of your Collections determines what your editors can do, what your pages can display, and what your integrations can access via the Webflow API.

Custom Code, GSAP, and the Limits of the Designer

Webflow's Designer handles a remarkable amount without custom code. But production sites for serious businesses almost always require going beyond it. Custom JavaScript interactions, third-party API integrations, membership and authentication logic, and advanced animation sequences all require code that lives outside Webflow's visual layer.

GSAP animations embedded via custom code embeds give you motion design capabilities that Webflow's native interactions cannot match — scroll-triggered sequences, morphing SVGs, timeline-controlled entrance animations. When these are implemented with performance in mind (respecting prefers-reduced-motion, avoiding layout thrash, loading GSAP only where needed), they add genuine value rather than just visual noise.

Our Webflow practice also covers the cases where Webflow itself is the right CMS backend but the frontend needs to move beyond Webflow's hosting. Webflow-to-Next.js builds — using the Webflow API to pull CMS content into a Next.js or Astro frontend — give you Webflow's editorial experience with full control over rendering, performance, and routing.

Integrations That Connect Webflow to the Business Stack

A Webflow site that exists in isolation from the rest of a business's systems is a missed opportunity. The platforms that matter — HubSpot, Salesforce, Stripe, Airtable, Memberstack, Outseta — all have APIs. Webflow has an API. The question is whether your agency knows how to connect them.

Common integration patterns we build:

• Lead capture to CRM: Form submissions routed to HubSpot or Salesforce with field mapping, tagging, and workflow triggers
• Membership portals: Gated content areas built with Memberstack or Outseta, with Webflow handling the design and the membership platform handling authentication and entitlements
• Dynamic content from external sources: Airtable or a custom database surfaced in Webflow via custom JavaScript and the Webflow API
• Stripe payment flows: Custom checkout experiences embedded in Webflow pages, with webhook handlers updating CMS content or triggering downstream automations

The middleware layer — often n8n, which we also build and maintain — is what makes these integrations reliable at scale rather than fragile one-off scripts.

Choosing Between WordPress and Webflow: A Technical Decision Framework

The question agencies and their clients face most often is not "which platform is better" but "which platform is right for this specific project." Answering that question well requires a framework that goes beyond surface-level comparisons.

Content Complexity and Editorial Workflow

WordPress wins on raw content modeling flexibility. Custom post types, custom taxonomies, meta fields managed through ACF or the native meta API, and the REST API give you a data layer that can represent almost any content structure. If your editorial team is managing thousands of items across complex taxonomies — a media archive, a product catalogue with deep attribute structures, a multilingual publication — WordPress is almost certainly the right choice.

Webflow's CMS is capable and pleasant to use, but it has structural constraints: Collection item limits on lower plans, reference field limitations, and no native support for deeply nested content relationships. For content-heavy sites with complex data models, these constraints matter.

Design Velocity and Visual Fidelity

Webflow wins on design-to-production speed and visual fidelity. A Figma file translated into Webflow by a developer who understands scalable class architecture can be in production in a fraction of the time it takes to build an equivalent WordPress theme from scratch. The visual feedback loop — making a change in the Designer and seeing it immediately in the browser — accelerates iteration.

For projects where the primary deliverable is a visually distinctive marketing site that needs to move fast, Webflow's model has a genuine productivity advantage.

Extensibility and Custom Functionality

WordPress wins on extensibility. The plugin ecosystem — despite its quality variance — gives you access to solved problems. Payment gateways, booking systems, membership platforms, learning management systems, and hundreds of other categories of functionality exist as WordPress plugins. When you need something that doesn't exist, the plugin API gives you a clean way to build it.

Webflow's extensibility is real but different in character. Custom code embeds and the Webflow API are powerful, but you are always working within a hosting environment you don't fully control. For applications that need server-side logic, database access, or complex background processing, WordPress (or a headless architecture) is the more natural fit.

Performance and Hosting Architecture

Both platforms can achieve excellent Core Web Vitals scores when built correctly. The variable is implementation quality, not platform capability.

WordPress on managed hosting — WP Engine, SiteGround, or a well-configured VPS — with proper caching (object caching, full-page caching, CDN) delivers sub-second load times. Webflow's hosting is Fastly-backed and globally distributed by default, which removes a category of infrastructure decisions from the project scope.

For teams that want to minimize infrastructure management, Webflow's hosting model is genuinely attractive. For teams that need control over server configuration, caching strategy, or data residency, WordPress on managed hosting is the answer.

The Decision Matrix in Practice

When a new project brief arrives at werun.dev, the platform decision follows a consistent logic:

• Complex e-commerce with custom logic → WordPress + WooCommerce
• Content-heavy site with complex taxonomies → WordPress
• Visually led marketing site with moderate CMS needs → Webflow
• Membership or gated content portal → Webflow + Memberstack/Outseta, or WordPress with a custom solution
• Enterprise marketing site needing editorial speed and design fidelity → Webflow, potentially headless
• Application-like functionality with significant backend requirements → WordPress or a custom stack

The honest answer is that both platforms are capable of more than most people give them credit for. The failure mode is not choosing the wrong platform — it is choosing the right platform and then implementing it poorly.

The Agency Opportunity: Depth Over Breadth

The shift in the CMS landscape creates a specific opportunity for agencies that choose depth over breadth. The market is saturated with generalist shops that will build you a WordPress site or a Webflow site without strong opinions about how it should be done. That work is commoditized, and the pricing pressure reflects it.

The agencies that are growing — and charging rates that reflect the value they deliver — are the ones that have developed genuine expertise in the platforms they work with. They know the edge cases. They know what breaks at scale. They know how to structure a CMS for a content team that will be using it in three years. They know how to build a plugin that survives a major WordPress update.

What Platform Expertise Actually Looks Like

For WordPress, it means understanding the hook system deeply enough to extend any plugin without modifying its source code. It means knowing when to use wp_remote_get versus a direct database query. It means building WooCommerce extensions that use the CRUD classes rather than direct database writes. It means writing REST API endpoints that respect authentication, capability checks, and the WordPress data validation pipeline.

For Webflow, it means building class architectures that a new developer can read and extend six months after launch. It means structuring CMS Collections so that the Webflow API responses are predictable and usable in downstream integrations. It means knowing when GSAP is the right tool and when Webflow's native interactions are sufficient. It means understanding the trade-offs between Webflow hosting and a headless architecture before the client asks.

Maintenance as a Service Line

One of the clearest differentiators between agencies that deliver long-term value and those that deliver projects is the maintenance retainer. Both WordPress and Webflow sites require ongoing attention — WordPress for security updates, plugin compatibility, and performance monitoring; Webflow for CMS content architecture evolution, custom code updates, and integration maintenance as third-party APIs change.

At werun.dev, monthly maintenance retainers are a core part of our service model for both platforms. They are not an upsell — they are the mechanism by which the sites we build continue to perform at the level they were launched at. A WordPress site without active maintenance is a security liability within eighteen months. A Webflow site without someone monitoring its integrations will fail silently when an API changes.

The Role of AI and Automation in Platform Work

The CMS landscape shift is also being shaped by AI and automation tooling. n8n workflows that connect Webflow form submissions to CRM pipelines, AI chatbots embedded in WordPress sites via custom REST API endpoints, and data enrichment pipelines that populate Webflow CMS Collections from external sources — these are not future capabilities. They are live in production today.

Our AI and automation practice at werun.dev is increasingly intertwined with our CMS work. A Webflow site connected to an n8n workflow that qualifies leads, enriches contact data, and routes opportunities to the right sales rep is a meaningfully more valuable asset than a static marketing site. A WordPress knowledge base connected to a RAG-powered chatbot that can answer customer questions with citations to specific posts is a customer support tool, not just a content repository.

The agencies that understand both the CMS layer and the automation layer — and can connect them — are positioned to deliver something that neither a pure-play WordPress shop nor a pure-play automation consultant can offer alone.
