Sanity vs WordPress.com Pricing 2026: Real Costs at Every Scale

Sanity CMS and WordPress.com are two of the most common recommendations developers pass to clients who ask 'what should I build on?' — and the pricing logic for each is almost completely different. Sanity charges per dataset bandwidth and API usage; WordPress.com charges per publishing feature and removes branding. Comparing them by headline plan price alone will mislead you.

What you actually get on the free tier

Sanity's free tier (Free plan) gives you three users, two datasets, 500k API CDN requests per month, 20GB bandwidth, and 5GB of asset storage. There is no watermark, no domain restriction, and no expiry. You can ship a real production site on the free plan if your traffic is modest.

WordPress.com's free tier gives you a yoursite.wordpress.com subdomain, 1 GB storage, WordPress ads served on your pages, and no custom plugins. It is not viable for a client-facing site without upgrading. The ads alone make it a no.

Paid plan structure and where costs jump

Sanity has two named paid tiers: Growth ($15/month per project) and Enterprise (custom). Growth removes most free-tier limits — 25 users, 25 datasets, 1M API CDN requests, 100 GB bandwidth, 100 GB storage. Overages are metered: $0.017 per 1000 additional API CDN requests, $0.10/GB additional bandwidth, $0.06/GB additional storage.

WordPress.com has four paid tiers as of mid-2026:

• Starter — $9/month (annual): custom domain, no ads, 6 GB storage. Still no plugins.
• Explorer — $18/month: 50 GB storage, still no third-party plugins.
• Creator — $40/month: unlimited plugins, Jetpack extras, ability to monetise.
• Entrepreneur — $70/month: WooCommerce, premium themes, priority support.

The critical inflection point for WordPress.com is Creator at $40/month, because that is where plugins unlock. Below that, you cannot install ACF, Yoast, WooCommerce, custom contact forms, or any third-party plugin. Many buyers do not realise this until after they have committed to a cheaper plan.

Hosting cost is apples to oranges

WordPress.com includes hosting — that is the product. Sanity is a content API; you still need a front end hosted somewhere. For a Next.js project, that is typically Vercel (Hobby free or Pro at $20/month per member) or a VPS.

So a fair apples-to-apples comparison for a small client site:

• Sanity Free + Vercel Hobby: $0/month. Legitimate production option for low-traffic sites with one developer.
• Sanity Growth + Vercel Pro: $15 + $20 = $35/month before usage overages.
• WordPress.com Creator: $40/month all-in, hosting included.

At that level they are roughly equivalent in price. But what you get is very different. Sanity + Next.js gives you a decoupled architecture, full control over rendering (SSR, ISR, PPR), and no platform lock-in on the front end. WordPress.com Creator gives you a managed monolith with the WordPress editor and plugin ecosystem — zero infrastructure overhead, but you cannot deploy your own rendering layer.

What actually triggers an upgrade on each platform

On Sanity, the triggers are almost always traffic-driven:

• Exceeding 500k API CDN requests/month (this is easier to hit than it sounds if you are not caching GROQ responses at the edge)
• Exceeding 20 GB bandwidth (large image libraries, un-optimised Sanity image URLs)
• Needing a fourth collaborator in the Studio

On WordPress.com, the triggers are feature-driven:

• Needing a custom plugin → Creator ($40)
• Needing WooCommerce → Entrepreneur ($70)
• Needing a custom domain without paying → Starter ($9)

WordPress.com's model gates capability behind price. Sanity's model gates capacity behind price. These are fundamentally different lock-in vectors.

Which one is actually cheaper over two years

For a content-only marketing site with a competent developer:

• Sanity Free + Vercel Hobby → year one: $0. Year two: $0. Unless traffic grows past free-tier limits.
• WordPress.com Creator → year one: $480. Year two: $480. Flat, predictable, no surprises.

For a site that needs plugins and is run by a non-technical editor without a developer on retainer, WordPress.com Creator's $40/month is genuinely good value. You are paying for managed infrastructure, automatic updates, and a familiar editing interface.

For a site being built by a developer who will own the front end, Sanity wins on total cost at every traffic level until you hit enterprise scale. The free tier is real, the Growth tier at $15 is cheaper than any plugin-capable WordPress.com plan, and you are not paying for hosting twice.

Egress and API costs at scale

This is where WordPress.com's pricing model actually becomes an advantage for some buyers. WordPress.com has no egress or API call charges — you pay a flat rate regardless of traffic. Sanity's Growth plan charges $0.10/GB over 100 GB bandwidth and $0.017 per 1000 API CDN requests over 1M/month.

If you are running a high-traffic editorial site with millions of monthly visitors, Sanity overage costs can accumulate. The fix is aggressive edge caching of GROQ responses and serving all images through next/image with a CDN prefix rather than direct Sanity CDN hits — but that requires developer time WordPress.com does not.

For non-developers or small teams without a developer on retainer, WordPress.com's flat pricing removes an entire category of infrastructure anxiety.

The honest recommendation

Choose Sanity if you have a developer, want a custom front end, and need full control over performance and rendering. The free tier is genuinely usable, Growth at $15 is cheaper than WordPress.com Creator, and the architecture will not paint you into a corner when requirements change.

Choose WordPress.com Creator or Entrepreneur if the buyer is non-technical, does not want a developer relationship, needs the WordPress plugin ecosystem, and values a single flat monthly bill with no infrastructure decisions.
