Sanity doesn't replace Webflow.It's a content hub. It stores your texts and images, then distributes them to a separately built site.
The change is therefore about your content, not your design.Your texts become reusable elsewhere, and stop being trapped on your pages.
| What you need to know |
|---|
| Sanity manages content. The display requires a separately developed site, usually with Next.js. Multilingual support is unlimited on all plans, whereas Webflow charges approximately $9 USD per additional language. Twenty people can work on it at no cost, versus $39 USD per design seat on Webflow. In exchange, you give up the visual editor: creating a page requires a developer. |
Sanity doesn't replace Webflow
It's the most common misunderstanding, and it comes at a high cost in disappointed expectations. Webflow does two jobs at once: it stores content and it designs pages.
Sanity does only one. You need to add a custom-built website, which will retrieve the content to display it.
Comparing the two amounts to comparing a warehouse and a store. The real comparison is between Webflow and the Sanity system plus custom-built website.
| In other words |
|---|
| A coupled system, like Webflow, brings content and its display together in the same tool. A decoupled system separates them: the content lives on one side, the website that displays it on the other. The two communicate through a programming interface, often called an API: a pass-through that delivers content to the website. |
Content separated from display, explained simply
In Webflow, a piece of text belongs to the page where you wrote it. Reusing it elsewhere means copying it again.
In Sanity, that same text exists as such. Your website displays it, your newsletter republishes it, your mobile app does too, without duplication.
The difference seems abstract until the day you correct a price. On structured content, the correction is made once and spreads everywhere.
Three concrete gains for your team
Beyond the principle, three differences are measured in dollars and hours.
The number of people working. Sanity welcomes twenty users free of charge. At Webflow, each person added is billed, from $15 to $39 USD depending on their role.
Content structure. You define your own fields, a price, a date, a fact sheet, instead of being stuck with generic blocks.
Content output. Everything goes through API, so nothing holds you back. Changing sites later doesn't force you to rewrite content.
| What you're comparing | Webflow Premium | Sanity, free plan |
|---|---|---|
| Content elements | 20,000 | 10 000 |
| People included | 1, then $15 to $39 USD | 20 |
| Languages | Approximately $9 USD per language | Unlimited |
| The site that displays | Included | To develop |
On raw volume, Webflow keeps the advantage with twice as many elements. Sanity's paid plan goes up to 25,000 documents, for $15 USD per seat.
Multilingual, without a bill per language
That's the point that speaks most to businesses here. French has been mandatory since Bill 96, and many organizations also serve an English-speaking clientele.
On Webflow, each language added is paid for, starting at around $9 USD per month. On Sanity, languages are unlimited, including on the free plan.
On two languages only, the gap remains modest. It becomes clear as soon as a third language comes into play, or regional content stands out.
| The calculation over three years |
|---|
| A bilingual site costs $34 USD per month on Webflow's side: $25 USD for the plan, $9 USD for the added language. Add two people to editing and you're approaching $2,300 USD over three years. The same conditions are free on Sanity's side. It remains to fund the site that displays the content. The switch is justified by the structure, rarely by the bill alone. |
What you leave behind
The subject deserves to be raised frankly, because it's often glossed over. Leaving Webflow for Sanity deprives you of its greatest asset.
- The visual editor disappears: no more mouse-based page layout.
- Creating a page template requires a developer, not an afternoon.
- Hosting and deployment are managed elsewhere, with another provider.
- Your Webflow animations don't translate as-is.
Your marketing team keeps control over text and images. But loses it on design, which goes back to a technical person.
| ⚠️ Not to be overlooked |
|---|
| Without a site developed in parallel, a Sanity project produces no visible pages. Budget this development from the start, never after content migration. Content that waits months for its site ends up outdated. |
What happens to your content during the transfer
The good news fits in one line: Webflow content exports. Collections come out as readable files, ready to be reshaped.
The tricky step isn't the export, but the reformatting. Your generic blocks must become named fields, which requires making choices.
Your page URLs, on the other hand, are preserved. The new site uses the same structure, and your Google rankings stay intact.
| Real case |
|---|
| An accounting firm migrates its 300-article blog and 40 service pages. The export takes one day. Field modeling takes three, and that's where result quality is decided. The public site develops in parallel and connects at the end. |
For which companies does this change make sense
The answer lies in your relationship with content, not the size of your organization.
A company whose website is a stable storefront has little to gain from switching. Webflow remains faster, simpler and less expensive.
An organization that publishes frequently, in multiple languages, and reuses its content elsewhere, will see returns quickly.
The most common trigger remains the need to distribute the same content to multiple places. Website, application, in-store screens, partners.
| In summary |
|---|
| Sanity manages content, not presentation. The website still needs to be built, and this cost is planned. The gains are seen in multilingual support, number of users, and content reuse. The drawbacks are seen in your team's visual autonomy. A stable storefront has nothing to gain from the switch: Webflow remains the most sensible choice. |
Does your content deserve this change? Let's talk about it →
Your questions about decoupled content
Do you need a developer to use Sanity?
To install it and build the website who displays it, yes. To write and publish afterwards, your team works alone in a simple interface.
Can we keep Webflow and add Sanity?
Technically possible, rarely relevant. Both tools then manage the same content, which doubles the work instead of reducing it.
Does SEO suffer from the change?
No, if the URLs remain identical and the new site loads just as fast. Both conditions are verified before going live.
How much does Sanity cost once your team is set up?
The free plan covers 20 people and 10,000 documents. Beyond that, expect $15 USD per month per seat on the paid plan.
What happens if Sanity shuts down one day?
Your content comes out via API in a standard format, at any time. This is precisely what distinguishes a decoupled system from a closed platform.
How long does this type of migration take?
A few days for the content itself. The actual timeline depends on the site to be developed, which happens in parallel.
