Squarespace vs WordPress： 完全比較
美しいデザインテンプレートのSquarespaceと、無制限のカスタマイズが可能なWordPressを比較。
The Big Picture
Squarespace and WordPress are two of the most popular ways to build a website, but they serve different needs. Squarespace is an all-in-one hosted platform known for stunning design templates and simplicity. WordPress is an open-source CMS powering over 40% of the web, offering limitless flexibility at the cost of complexity.
In this guide, we compare them across 10 critical categories — no favoritism, just honest analysis. Whether you are a creative, a business owner, or a developer, this comparison will help you decide. And if neither feels right, we have a third option worth considering.
比較表
主な違い
デザイン品質
Award-winning templates with consistent, polished aesthetics. Every template is mobile-responsive and professionally designed. Limited layout flexibility but everything looks beautiful out of the box.
Thousands of free and premium themes with wildly varying quality. Full design control with page builders (Elementor, Divi) or block themes. Requires more effort to achieve a polished look.
Verdict: Squarespace wins for out-of-the-box design quality. WordPress offers more variety but requires curation and effort to match Squarespace's polish.
使いやすさ
Intuitive visual editor with structured sections. Clean interface with guided setup. No coding required. Slightly less flexible than pure drag-and-drop but very approachable.
Block editor (Gutenberg) is improving but still has a learning curve. Managing themes, plugins, hosting, and updates adds complexity. Page builders help but add another layer to learn.
Verdict: Squarespace is easier for most people. WordPress is manageable but demands more technical comfort.
料金
Plans from $16/mo (annual billing). All plans include hosting, SSL, CDN, and templates. No free plan — only a 14-day trial. Business plan at $33/mo. Commerce plans from $27/mo.
Software is free. Hosting ($3-30/mo), domain ($12/yr), premium themes ($0-80), plugins (many free, premium $0-300/yr). Total cost: $5-100+/mo depending on needs.
Verdict: WordPress can be cheaper for basic sites. Squarespace is more predictable — one price includes everything. For complex sites, costs converge.
SEO
Clean URLs, auto-generated sitemaps, meta tag editing, and built-in SEO checklist. Good fundamentals but limited advanced controls. No access to server-level optimization.
Industry-leading SEO plugins (Yoast, Rank Math). Full control over technical SEO, schema markup, redirects, and performance. Better page speed potential. Dominant for content marketing.
Verdict: WordPress wins for serious SEO. More tools, more control, and better performance optimization options.
Eコマース
Built-in commerce features on Business plan and above. Beautiful product pages, inventory management, subscription selling, and integrated payment processing. Best for small-to-medium stores with visual products.
WooCommerce powers 28% of all online stores. Extremely flexible with thousands of extensions. Handles complex catalogs, B2B, subscriptions, and multi-vendor marketplaces. Requires more setup and maintenance.
Verdict: Squarespace is better for small, design-focused shops. WordPress/WooCommerce dominates for larger or complex e-commerce operations.
ブログ
Clean blog layout with categories, tags, and scheduling. Good for visual blogs with podcast and video support. Limited compared to dedicated blogging platforms. RSS feeds included.
WordPress was born as a blogging platform and it shows. Superior content management, editorial workflow, custom post types, comment management, and unlimited blogging plugins. The gold standard for content publishing.
Verdict: WordPress wins decisively. It was built for blogging and remains unmatched for content-heavy sites.
カスタマイズ
Template-based with structured sections. CSS and limited JavaScript injection available. Code blocks for embeds. Cannot modify the core platform or add arbitrary server-side functionality.
Unlimited customization. Full access to PHP, CSS, JavaScript, and the REST API. 60,000+ plugins. Child themes for safe modifications. Custom post types, taxonomies, and hooks for any feature imaginable.
Verdict: WordPress wins by a wide margin. If you need deep customization, WordPress has no ceiling. Squarespace prioritizes design guardrails over flexibility.
Hosting & Reliability
Fully managed hosting included in all plans. SSL, CDN, automatic backups, and 99.98% uptime SLA. No server management whatsoever. Consistent performance across all sites.
You choose your host. Quality ranges from excellent (WP Engine, Kinsta) to poor (cheap shared hosting). Managed WordPress hosting solves most issues but costs $20-50+/mo. You handle backups and updates.
Verdict: Squarespace is hassle-free with reliable hosting included. WordPress gives more choice but the burden is on you.
Customer Support
24/7 email and live chat support from Squarespace directly. Comprehensive help documentation and video tutorials. Webinars and community forum. One company handles everything.
No official support (it is open-source). Support depends on your hosting provider, theme developer, and plugin authors. WordPress.org forums are community-driven. Professional help available for hire.
Verdict: Squarespace wins with unified, direct support. WordPress relies on a fragmented ecosystem of providers.
Scalability
Handles moderate traffic well. No plugin bloat issues. Limited by platform capabilities for very large or complex sites. Enterprise plan available for high-traffic sites but still constrained.
Scales to any size with proper infrastructure. Powers enterprise sites (Disney, BBC, Sony). Requires investment in hosting, caching, and optimization. Plugin conflicts can create scaling challenges.
Verdict: WordPress scales further but requires expertise. Squarespace is reliable for small-to-medium sites without the scaling headaches.

Choose WordPress if you...

- Want access to 60,000+ plugins for any feature
- Plan to scale to a large or enterprise-level website
- Have technical skills or budget for a developer
