Sanity vs Webflow comes up more often than you'd expect when clients are scoping a content site. Both can produce a fast, polished result — but they sit at completely opposite ends of the control spectrum, and choosing the wrong one creates real pain later. Here's how I think through the decision for Next.js projects.
What each tool actually is
Webflow is a visual website builder with a built-in CMS, hosting, and a designer-first editor. You draw layouts in a canvas, bind them to CMS fields, and publish — all inside Webflow's infrastructure. There's no separate deployment step unless you go headless (Webflow's API plan), and even then, you're working around a tool that was never designed as a pure API.
Sanity is a headless CMS and nothing else. It gives you a content API (GROQ over HTTP), a fully customisable Studio, and no opinions about your frontend. You bring the Next.js app, the hosting, the image CDN strategy, and the deployment pipeline. More moving parts, more control.
Editor experience
Webflow wins on day-one editor experience for non-technical teams. The CMS editor is visually tied to the design — editors see roughly what they'll publish. There's nothing to install, and Webflow University covers most questions.
Sanity's Studio is excellent once configured, but it needs configuration. Out of the box, editors see fields, not pages. You need Portable Text components, custom previews, and Presentation mode wired up before it feels as intuitive as Webflow. For a team of two editors running a blog, Webflow has a lower onboarding cost. For a team managing 10 content types, 4 locales, and document relationships, Sanity's structured model scales better.
Developer control and Next.js integration
Webflow's native hosting can't run Next.js at all. If you want App Router, RSC, or ISR, you must use Webflow's CMS API (available on Business plan and above, $39/month minimum). The API is REST-only, rate-limited, and the data model reflects Webflow's visual metaphors rather than your own schema. Querying nested references involves multiple round-trips — there's no GROQ equivalent.
Sanity integrates with Next.js natively. GROQ projections let you fetch exactly the shape you need in a single request, refs are resolved in the query, and next-sanity gives you typed fetchers with built-in draft mode and live preview. TypeGen produces TypeScript types from your schemas, so your RSC components stay type-safe end to end.
// app/posts/[slug]/page.tsx — Sanity GROQ fetch, typed
import { sanityFetch } from '@/lib/sanity/client'
import type { PostQueryResult } from '@/sanity.types'
const POST_QUERY = `*[_type == "post" && slug.current == $slug][0]{
title,
body,
"lqip": mainImage.asset->metadata.lqip,
"dimensions": mainImage.asset->metadata.dimensions
}`
export default async function PostPage({ params }: { params: { slug: string } }) {
const post = await sanityFetch<PostQueryResult>({ query: POST_QUERY, params })
// ...
}
You can't write anything equivalent with Webflow's API without chaining multiple REST calls and manually assembling the shape yourself.
Pricing side-by-side
| Feature | Webflow | Sanity |
|---|---|---|
| Free tier | 2 pages, no custom domain, 50 CMS items | 3 users, 10 k CDN req/month, 3 datasets |
| Entry paid plan | Starter $14/mo (2 locales, 100 CMS items) | Growth $15/mo (20 users, 25 k CDN req/month) |
| Custom code / API access | Business $39/mo | All plans (REST + GROQ) |
| CMS API (headless) | Business $39/mo minimum | Included on free tier |
| Localisation | Add-on, $9/mo per locale | Plugin, included in Growth |
| Editor seats | Included in plan | Priced at Growth tier |
| Bandwidth | 50 GB on Business | Sanity CDN; Next.js host bills separately |
| Image transforms | Included, Webflow CDN | Included via Sanity image pipeline |
For a simple marketing site with five pages, Webflow's Starter is cheaper and requires no developer time after launch. For anything that hits the API, you're on Business ($39/month) and the cost math changes. Add localisation ($9 per locale), and a three-language site costs $66/month from Webflow before hosting. Sanity Growth at $15/month covers 20 users and plugin-based i18n with no per-locale charge.
The real cost difference is developer time. A Webflow site can go live with zero custom code. A Sanity + Next.js site needs a developer who can build and maintain the frontend. For content-heavy products where that developer exists anyway (or is you), Sanity's monthly cost is lower and the capability ceiling is much higher.
SEO and Core Web Vitals
Webflow's hosted output is server-rendered HTML, which is fine for basic SEO. The problem is you can't control rendering strategy. There's no ISR, no PPR, no edge caching granularity. JSON-LD can be injected via custom code embeds, but it's brittle.
With Sanity + Next.js, you own the full metadata pipeline — generateMetadata, per-route JSON-LD components, and image optimisation via next/image with LQIP from Sanity's metadata palette. LCP is a known quantity you can instrument and tune. Webflow sites regularly score well on Lighthouse until they accumulate designer-added animations, third-party embeds, and large hero images without proper sizes attributes.
When to pick Webflow
- The client owns and updates the site themselves, no developer on retainer
- The design needs to stay editable visually by non-technical staff
- Budget doesn't support ongoing Next.js frontend maintenance
- The site is a brochure with fewer than 50 CMS items and no complex data relationships
When to pick Sanity + Next.js
- Content has relationships: authors, categories, tags, referenced media
- Multiple locales with structured field-level translation
- Performance requirements are contractual — you need measurable LCP and CLS targets
- The product is the content: a publication, a docs site, or an app that blurs the CMS line
- A developer will be involved long-term anyway
The edge case: Webflow as design, Sanity as CMS
Some teams try to export Webflow HTML and run it inside a Next.js app. It rarely ends well — the output is tightly coupled to Webflow's class conventions and JavaScript. The cleaner split is to use Webflow for design prototyping and hand the final designs to a developer who implements them in Next.js against Sanity. You get Webflow's visual design speed without locking your production app into Webflow's runtime.
