Why We Build with Prismic and Strapi Instead of WordPress or Squarespace

Most people are familiar with WordPress because it does two things at once: it stores and manages your content, and it renders your website. The design, the layout, the templates, the pages visitors see in a browser, all of it lives inside the same system where your team drafts and publishes content. This bundled approach is what makes WordPress quick to start with, and it is also what creates most of its long-term problems.

A headless CMS separates these two layers entirely. The CMS becomes a content backend, accessed via an API, with no opinions about how that content gets displayed. Prismic and Strapi store your content, manage your media, and expose everything through a clean API. Your website, built independently with a modern frontend framework, fetches that content and renders it however the design requires. "Headless" simply means the CMS has no built-in frontend: no head.

What that separation enables:

• The same content can power your website, a mobile app, and any other surface from a single source of truth
• Your frontend can be built with any technology, with no restrictions imposed by the CMS
• The website can be completely redesigned without touching the CMS or migrating any content
• Either layer can be improved or replaced independently, without risk to the other

Prismic is a hosted platform built around a visual page builder called Slice Machine, particularly strong for marketing teams that want to build and iterate on page layouts without developer involvement. Strapi is open-source and self-hosted, giving development teams full control over content models, hosting, and data ownership. Both deliver content via API and place no constraints on how the frontend is built.

“If the CMS and the website are the same thing, you cannot change one without risking the other. Headless ends that tradeoff permanently.”

WordPress is the most targeted CMS on the web by a significant margin. According to annual security reports from Sucuri, a leading web security firm, WordPress consistently accounts for the vast majority of all CMS-based website hacks tracked globally, year after year, across every industry. That is not a coincidence or a one-year anomaly. It is a structural consequence of how the platform is built.

The plugin ecosystem is the primary culprit. WordPress's repository contains more than 59,000 plugins, many of them maintained by individual developers or small teams without dedicated security resources, contact information or support. New vulnerabilities in WordPress plugins are disclosed every single week. A single outdated plugin can expose your database, admin access, and customer data to attackers who run automated scanners across the web looking for exactly these entry points. WordPress installations also expose attack surfaces by default: the /wp-admin login page, the xmlrpc.php endpoint, and the REST API are all publicly reachable and actively probed.

Squarespace presents a narrower attack surface than WordPress because it is a closed platform, but it introduces a different kind of risk: your entire website lives on Squarespace's infrastructure, under their security posture, with no visibility into what is protecting it. If Squarespace has an incident, you are affected with no recourse or control.

Headless CMS platforms change this picture entirely. Prismic serves content through a secure, read-only API. The admin interface where your team edits content is completely separate from your public-facing website and requires authentication to access. Strapi runs on infrastructure you control, with no public-facing PHP execution and no admin login attached to the site your visitors see. There is no plugin attack surface. There is no xmlrpc.php equivalent. Your website fetches JSON from an API; it is not a PHP runtime waiting to be discovered by a scanner.

“With WordPress, every plugin you install is a new attack surface. With a headless CMS, the editing interface is never reachable from your public-facing site at all.”

The most common concern we hear from clients considering a move away from WordPress is this: our marketing team knows WordPress. If we change platforms, they will have to learn something new. This is a fair concern. The answer is that the learning curve is smaller than most people expect, and the editorial experience on the other side is genuinely better.

Prismic gives content editors a visual, structured interface for building and editing pages. Sections can be reordered, images swapped, text updated, and new pages published, all without touching a line of code. Strapi is the same concept from an editor's perspective: the admin is filled with familiar text areas, single-line fields, and media pickers, so day-to-day updates are plain typing and choices in a form, not code, and no developer has to be involved for routine content changes. Both platforms support media libraries, publish and unpublish controls, role-based access, content previews, scheduled publishing, and version history so you can see prior edits and roll back when needed.

What editors can do in either platform, without any developer involvement:

• Create and publish new pages, blog posts, or any structured content type
• Update copy, images, and structured fields across any part of the site
• Reorder page sections and adjust layouts within defined content components
• Preview changes before they go live
• Manage media assets in a shared library
• Control publish state and schedule content for future release dates

What editors struggle with in WordPress, even with the Gutenberg editor, is the same thing developers struggle with: plugin conflicts that break block layouts after an update, page builder components that render differently in preview versus production, and content structures designed for the theme's expectations rather than the business's actual content needs. The editing experience is unpredictable in ways that headless CMS tools simply are not.

How the platforms compare across key categories

Yoast SEO is the plugin that made WordPress feel like the default choice for SEO. Install it, follow its green dots, and you're doing SEO. This is one of the most persistent myths in web marketing. Yoast is a checklist tool. It tells you whether your target keyword appears in the first paragraph and whether your meta description is the right length. These checks are not meaningless, but they represent a small fraction of what actually determines how a site performs in search.

Real, durable SEO involves technical foundations that Yoast does not control: Core Web Vitals scores (LCP, INP, CLS), structured data and JSON-LD schema markup, crawlability and indexability signals, canonical URL management, sitemap accuracy, E-E-A-T content signals, and, increasingly, how well a site performs in AI-powered search experiences like Google's AI Overviews and answer engines. Yoast shows a green dot when your keyword density looks right. None of the above appears in its dashboard.

On a headless site, every one of those factors is fully programmable and under complete control. Every meta tag, every JSON-LD schema block, every canonical URL is authored in code, applied consistently across templates, and testable before it ships. There are no plugin conflicts affecting your structured data. Your schema is written deliberately for each page type and validated before deployment, not generated by a third-party script guessing at your content type.

We also use modern AI-powered tooling to audit and improve SEO continuously, running comprehensive audits with parallel specialist agents that cover technical SEO, content quality, schema validation, Core Web Vitals, and AI search readiness simultaneously, then using agents to implement the prioritized findings. If you'd like to understand what that process looks like in practice, we've written about it in our post on AI-powered SEO auditing.

“Yoast tells you if you used your keyword enough times. Real SEO tooling tells you your Organization schema has a JSON-LD parse error that is costing you rich-result eligibility in search.”

Even if you never write a line of code yourself, this one matters, because platform constraints directly affect what you can build, how quickly it happens, and what it costs. WordPress and Squarespace are built around fixed conventions: themes, block editors, template hierarchies, PHP rendering pipelines. Those conventions make getting started fast. They also create a ceiling.

What platform constraints look like in practice

• Design compromises. Layouts that a designer specifies may become impossible or require extensive workarounds because WordPress themes have their own strong opinions about page structure.
• Feature workarounds. Capabilities not supported by existing plugins require custom development that navigates plugin conflicts, compatibility matrices, and maintenance overhead at every step.
• Performance overhead. WordPress outputs HTML generated by PHP templates with decades of accumulated conventions. Optimizing for modern performance standards means fighting the platform's default output, not building for it.
• Hard limits on Squarespace. Squarespace defines a set of content blocks and page structures. Anything outside that defined set is simply unavailable, regardless of how reasonable the request.

When we build with a headless CMS and a modern frontend stack using TypeScript, React, and a framework like TanStack Start, none of those constraints exist. The design is implemented as specified. Features are built with the right tools for the job, not shoehorned into a plugin architecture. Performance is optimized from the start, not bolted on afterward.

This translates to fewer compromises in the final product, fewer developer hours fighting the platform, and fewer conversations about what the platform simply will not allow.

“Building a complex feature on WordPress often means finding a plugin that covers 80% of what you need, then paying a developer to fight the other 20%. With a headless stack, we build the 100% you actually need.”

The scenario plays out regularly. A business built their website on WordPress several years ago. It worked fine. Now they want to refresh the design, modernize the architecture, or add new functionality. The project estimate comes back larger than expected because the content, the presentation layer, and the CMS are tightly coupled. Migrating content, rebuilding templates, re-evaluating every plugin for compatibility with the new theme; it is effectively a rebuild even when the goal was only a redesign.

With a headless CMS, a redesign is a frontend project. The content stays exactly where it is in Prismic or Strapi. Editors continue working throughout the development process. The new frontend fetches the same content from the same API. When the build is complete, the switch is a deployment: not a migration, not a rebuild, not a page-by-page content transfer.

This advantage compounds over time. Each subsequent design iteration costs less than the previous one. When a new frontend framework becomes the better choice, the frontend is rebuilt while the content layer stays intact. When you add a mobile application, it reads from the same API. When you expand to new markets and need localized content, the CMS supports it without rebuilding the delivery layer. The decoupled architecture is not just a technical preference; it is a practical long-term asset that reduces the cost of every future change.

“Every version of a WordPress site is effectively a new WordPress site. Every version of a headless frontend reads the same content. That is not a minor efficiency; it is a fundamental difference in how much you reinvest in the same ground each time.”

WordPress is free software. Squarespace starts at around $16 per month. These are the numbers that show up first in any platform comparison, and they are the ones that anchor most initial decisions. They are not, however, the full cost of what either platform actually requires over the life of a website.

A realistic total cost of ownership for a WordPress site includes: managed WordPress hosting to avoid shared servers with other compromised sites ($20–$100 per month), a premium theme with annual renewal for security updates ($50–$200), premium plugins for SEO, forms, performance, security, backups, and caching ($30–$300 each, per year), developer time navigating plugin conflicts and update failures, and the eventual rebuild cost when the platform's ceiling is finally reached. These costs are not hypothetical. They accumulate consistently across almost every long-running WordPress project.

Squarespace's cost is more predictable but introduces a different liability: vendor lock-in. Your content lives in Squarespace's infrastructure, not yours. Moving to a different platform means a full content migration and a complete rebuild of the site. You are renting access, not owning an asset, and the terms of that rental can change.

Prismic has a generous free tier for smaller sites and straightforward paid plans with no hidden plugin requirements. Your content is always accessible via API and fully portable. Strapi is open-source with no licensing cost at all, deployed to infrastructure you control, with costs that scale only with actual usage. Neither platform charges extra for features that should simply be standard.

The deeper cost of "cheap" platforms is not in the initial license; it is in the developer time spent fighting constraints, the security incidents that cost far more to clean up than to prevent, and the rebuild cycles that happen sooner than planned because the platform ran out of room.

“There is a reason enterprises at scale consistently move away from WordPress. The cost is not the license; it is the ceiling.”
