Website builder, Webflow or Next.js/Astro: which website stack fits your business
Which website stack fits your business: builder, Webflow, or Next.js/Astro with Sanity? Decision matrix for non-tech leaders, 2026 costs, 4 questions.
For a B2B company that runs its website as a sales channel, Next.js or Astro with Sanity as the content database is the technical foundation without item, language, or performance ceilings in 2026. Webflow remains a good choice up to a limit you can name precisely, and website builders like Wix or Squarespace fall short of that ambition. We have built on all three tiers: our own website ran on Wix until 2026 and now runs on Next.js and Sanity. This article is the hub for the topic: the short answer, a decision matrix for non-technical leaders, the three tiers in detail, running costs for 2026, the four questions that settle the decision, and three projects that show how we decide.
Key takeaways
- Three tiers, one direction: builder (Wix, Squarespace, Jimdo, WordPress with Elementor), Webflow, and a code system with Next.js or Astro plus Sanity. With every tier, more of the technology belongs to you.
- Our default for B2B websites is Astro with Sanity; Next.js as soon as app logic, login, or server-side data per request are needed. in-sync.io runs on Next.js. Multiple languages, programmatic pages, and AI-assisted content operations are the base architecture there, and a workaround in Webflow and Wix.
- Webflow is good until you need one of four things: more than 40 collections or 20,000 CMS items, languages without a $9-29 surcharge per language per month, custom logic that does not run through custom code, or an export that includes your content.
- Running platform costs: Astro or Next.js with Sanity Free typically $0-20 hosting per month, Webflow Premium $25 per month per site plus $9-29 per additional language, Wix $17-159 per month per site.
- Your marketing team keeps editing: Sanity Presentation Mode opens the matching field when you click text in the live preview. "Then my team can't change anything" no longer holds in 2026.
The short answer
Builder, Webflow, or Next.js: for a B2B company that wants its website to win inquiries and runs content as a system (multiple languages, a growing knowledge section, programmatic pages, integrations), we recommend a code system built on Next.js or Astro with Sanity as the content database in 2026. It gives you every lever Google and AI crawlers read, has no item or language limits, and runs with almost no recurring platform fees.
Webflow is the good middle option: strong on design, editor, and speed to launch. It fits as long as you stay within 40 collections and 20,000 CMS items, pay for every additional language as an add-on, and need no application logic of your own. We are a certified Webflow partner and support existing clients on it. These limits are not an opinion, they are in Webflow's own documentation.
Website builders like Wix, Squarespace, Jimdo, IONOS, or WordPress with Elementor fall short for B2B websites with ambition: a rented foundation, plugin dependency, a performance ceiling, no access to the technical base, a fee per site, and lock-in at export. We used Wix Studio ourselves. We no longer recommend it because it does not keep up with today's system.
Decision matrix for non-technical leaders
Read the table row by row. Wherever your company lands in the right column, you need the code system. If you land in the middle everywhere, Webflow is enough.
Decision matrix for non-technical leaders
| Criterion | Builder (Wix, Jimdo, Squarespace, Elementor) | Webflow | Next.js/Astro + Sanity |
|---|---|---|---|
| Design freedom | Templates with room to adjust, limits on custom layouts and animation | Free-form design, clean HTML/CSS, interactions in the editor | Anything a browser can do: custom components, 3D, scroll animation |
| Editor for marketing | Simple, but layout and content are mixed | Designer editor with a learning curve, CMS editor is simple | Sanity Studio plus Presentation Mode: click text in the live preview and the field opens, layout stays protected |
| CMS structure | Flat lists, few field types, hardly any relations | Collections with references, 40 collections and 20,000 items (Premium) | Your own content model with no item cap (Sanity Free: 10,000 documents, Growth: 25,000), any relation you need |
| Multilingual | Usually a copy of the site per language, hreflang (the tag that says which language version belongs to which) by hand | Add-on: $9 per language per month (up to 3), $29 (up to 10) | No surcharge per language, translated URL segments, hreflang generated in code |
| Performance | Ceiling set by platform scripts and plugins, no control | Good, but webflow.js loads on every page, no access to caching or the image pipeline | Astro: 0 KB JavaScript for static content, Next.js: server rendering, full control over caching and images |
| SEO/GEO levers | Meta fields and a sitemap, the rest via plugins | Meta, schema via custom code, 301 redirects, automatic sitemap | Schema, sitemap, llms.txt, IndexNow, internal linking, rendering: all controlled in code |
| AI content systems / programmatic pages | API and MCP server available at Wix, limited or absent at other builders; template and rate limits | API and MCP server exist, capped by item, collection, and list limits | Base architecture: Sanity API and Sanity MCP for agents, hundreds of pages from one template |
| Running costs (2026, per site) | Wix $17-159/month | $25/month Premium plus localization, plus workspace from $19 | $0-20/month hosting (Vercel Pro, one seat), Sanity Free |
| Lock-in / export | No runnable export | HTML/CSS/JS export without CMS content and without interactions | Code lives in your Git repository (the code archive you own), content exports from Sanity, hosting is your choice |
| Who maintains it | You, until a plugin breaks | Marketing maintains the CMS, design changes need Webflow skills | Marketing maintains content, developers maintain code; agency or in-house team |
The three tiers: what sits behind the names
Three tiers, three kinds of control. What each one does and where it ends.
Tier 1: website builders
Wix, Squarespace, Jimdo, IONOS, and WordPress with Elementor or Divi share one trait: you rent the foundation. The platform decides which scripts load, how images are delivered, and what you are allowed to export. WordPress adds the plugin chain, and every plugin is an update risk and a load-time factor. For a B2B company that sells through its website, it is a ceiling you hit as soon as the website is meant to be more than a business card.
Tier 2: Webflow (and Framer)
Webflow is a visual editor that outputs clean HTML and CSS, with a CMS that stores content in "collections" (lists of entries with defined fields). Design freedom, the editor, and speed to launch are strong. The limits are hard and documented: 20,000 CMS items and 40 collections on the Premium plan, at most 40 collection lists and 10 nested lists per page, 100 items per list without pagination. Every language costs extra. Custom logic only works through custom code that lives outside the editor. Framer sits on the same tier with a different focus, and Webflow vs. Framer sorts that out. If you are weighing Webflow against a builder, read Wix vs. Webflow.
Tier 3: Next.js or Astro + Sanity
There is no editor that builds pages here. There is code that developers write, and a headless CMS: a CMS that only manages content and delivers it through an interface to any frontend. Sanity is our choice, and we explain what a headless CMS is and why Sanity in separate articles. Astro builds the website statically: content is baked from Sanity into finished HTML at build time, and only interactive parts (Astro calls them "islands") load JavaScript. Next.js renders on the server per request or statically and is the choice for login, real-time data, and app logic. Our default for B2B websites is Astro with Sanity; Next.js as soon as app logic, login, or server-side data per request are needed. in-sync.io runs on Next.js. The direct comparison of both against Webflow is in Webflow vs. Next.js.
Editor for marketing: who changes what
Keep two things apart: maintaining content and changing layout. Builders allow both in the same editor. Webflow separates content (CMS) from layout (Designer); layout changes there need Webflow skills. In a code system, marketing maintains content and the layout lives in code.
For that, Sanity has Presentation Mode: your team sees the live website in a preview, clicks a headline, and the exact field holding that text opens on the right. At LeanWave the client maintains 64 documents this way, and a webhook (an automatic notification to the hosting) triggers a rebuild of the website after every change. What marketing cannot do there: restructure sections or invent new page types. That boundary keeps the design clean for years.
CMS structure, multilingual sites, and programmatic pages
With a code system and Sanity as a structured content database you control the entire chain programmatically: content model, page templates, content, internal linking, schema, sitemap, deploy. AI agents create, check, and maintain content through the Sanity API and the Sanity MCP server (an interface through which AI models work directly with the CMS). From structured data, hundreds or thousands of pages emerge from one template: industries × services × cities, glossaries, comparison pages.
For context: Webflow and Wix also offer official APIs and MCP servers, so an AI agent can reach the content on all three tiers. What separates the tiers are the limits behind that access. On tier 2 the CMS cap stops you (20,000 items and 40 collections on Webflow Premium, comparable limits at Wix), plus API rate limits and fixed template rules. And what the agent never reaches on tiers 1 and 2: rendering, caching, schema, sitemap logic, and internal linking, because those live at code level. Programmatic pages remain a detour there; on tier 3 they are the building principle.
Before you plan pages from a template, plan the substance per page. Without it, Google classifies the pages as doorway pages (pages that exist only for search engines) and demotes them. We have been through that demotion ourselves and needed months to get out of it.
The same comparison applies to multilingual sites. In a code system, a second language is a second document per piece of content and one rule in code that translates paths and sets hreflang. LeanWave runs bilingually this way, with no surcharge per language. In Webflow, localization is an add-on: $9 per language per month up to three languages, $29 per language up to ten.
Performance and SEO/GEO levers
Builders load platform scripts you cannot switch off. Webflow loads its interaction runtime webflow.js on every page, and you have no access to caching headers (the rules for how long browsers and networks store a page) or the image pipeline. Astro delivers 0 KB of JavaScript for static content by default. In numbers: leanwave.com, which we build statically with Astro, loads about 39 KB of JavaScript in three files on its home page. One of our Webflow sites loads about 740 KB in thirteen files at the same place (our own measurement, 13 September 2026). What those scores mean is covered in Core Web Vitals.
For SEO and GEO (generative engine optimization: becoming visible in ChatGPT, Gemini, Perplexity, and Google AI Overviews), what counts is what crawlers read. A code system gives you every lever: full server rendering, FAQPage and BreadcrumbList schema per page type, sitemap logic, llms.txt, IndexNow submission on every change, internal linking by rules instead of by hand. in-sync.io uses exactly that for 49 knowledge articles, 10 service pages, and 17 city pages. Webflow delivers clean basics and schema through custom code. Builders deliver meta fields. How GEO differs from SEO is in Generative Engine Optimization.

What the three tiers cost to run (2026)
| Item | Builder (Wix) | Webflow | Next.js/Astro + Sanity |
|---|---|---|---|
| Platform plan | Light $17, Core $29, Business $36, Business Elite $159 per month | Starter $0 (50 CMS items), Basic $15 (no CMS), Premium $25 per month | Framework $0 (open source) |
| Workspace / seats | Included | Core $19, Growth $49 per month | Vercel Pro $20 per developer seat per month incl. $20 usage credit, unlimited viewers |
| CMS | Included, limits per plan | Included from Premium, 20,000 items | Sanity Free: 20 seats, 10,000 documents, 100 GB assets, Presentation Mode included. Growth $15 per seat |
| Second language | Depending on plan, a copy of the site | $9 per language per month (up to 3), $29 (up to 10) | $0 |
| Typical monthly total | $17-159 per site | $25-54 per site plus workspace | $0-20 hosting |
The math for a single company: Astro or Next.js with Sanity Free typically runs on $0-20 hosting per month instead of $25-54 for Webflow Premium with localization, and with three languages the gap widens. In a code system the cost block sits in development, not in the license. What a project costs is covered in web development cost and on our web development agency page. Vercel is not mandatory: Netlify, Cloudflare Pages, or your own server work as well.
Lock-in and export: who owns your website
With a builder you own the content, not the website. A runnable export does not exist. Webflow exports HTML, CSS, and JavaScript, but without CMS content and without the interactions as a working system. You get a shell. In a code system the code sits in your Git repository, content exports from Sanity, and you switch hosting in an afternoon. How a move away from Webflow works in practice is in migrate Webflow to Next.js.
Four questions that settle the decision
If you only want to answer four questions, answer these. They settle the tier in almost every project.
How many pages will the website have in three years?
Up to about 30 pages, one or two languages, no programmatic pages planned: Webflow is enough. A knowledge section, glossary, city pages, or several languages planned: code system, because item caps and language surcharges become the brake.
Who maintains content, who maintains design?
If marketing only maintains content, Webflow and Sanity are equal. If marketing should also build layouts, Webflow has the edge. If AI agents should create and check content, code system.
Does the website need its own logic or integrations?
Login, configurator, CRM connection, real-time data, calculator: Next.js. A pure marketing website with a form: Webflow or Astro.
What happens when you change agencies?
If "rebuild" is an acceptable answer: Webflow. If code and content must come with you: code system.
Every answer that lands on the code system means a migration later if you start in Webflow. So weigh a migration in three years against the extra effort now.
When a builder, when Webflow, when Next.js/Astro + Sanity
The short version as a decision rule, in the order we work through it in a first call.
A builder is only enough if
All of these have to apply, not just one.
- the website is a legal notice with contact details and should stay that way
- there is no budget for an agency and nobody will do SEO
- you accept that a later move means a rebuild.
Choose Webflow if
Three or more hits speak clearly for Webflow.
- design and speed to launch tip the scale
- your marketing team should build layouts itself, without developers
- the website has up to about 30 pages, one or two languages, and no programmatic pages planned
- no application logic of your own is planned. Our Webflow agency builds and supports exactly these projects.
Choose Next.js or Astro + Sanity if
Here a single point is enough if it holds long term.
- content is a system: several languages, a knowledge section, programmatic pages, AI-assisted maintenance
- performance without a ceiling and every SEO/GEO lever should live in code
- integrations, login, or real-time data come into play (then Next.js rather than Astro)
- code and content should belong to you, independent of platform and agency.
How we decide on a project
in-sync.io, our own website: from tier 1 straight to tier 3. Wix swapped for Next.js, Sanity, and Vercel in 2026 with no stop at Webflow, because languages (DE/EN with hreflang), page count (49 knowledge articles, 10 service pages, 17 city pages), and SEO/GEO levers (server rendering, llms.txt, IndexNow, FAQPage schema) were fixed from the start. Next.js rather than Astro because of app logic and server-side functions. Where it stands: the Wix website ranked for practically nothing, the new one has been live since June 2026, and rankings are building.
LeanWave (Otto ID Solutions, RFID for textile services and laundries): tier 3 with Astro. Astro static, Sanity, Tailwind (a CSS system for styling), Vercel. Bilingual EN/DE with translated URL segments and reciprocal hreflang. 64 documents, 86 image assets, Presentation Mode active, rebuild via webhook on every change. Astro rather than Next.js because the website needs no per-request logic and 0 KB JavaScript for static content settles the performance question.
Yarowa, an international B2B client with a five-language website: from tier 2 to tier 3. Originally built in Webflow, the Webflow export was ported 1:1 to Astro and hosted on Vercel: 5 languages, 21 page templates, 163 sections, design unchanged. The move to Sanity with Presentation Mode is in planning. It is the proof that Webflow to Astro works without touching the design. Further Astro and Sanity projects: Ullsteinhaus (Astro, React, Three.js for 3D in the browser, Sanity) and Monteval (Astro, GSAP for animation, Sanity).
Our process on every move: a pre-crawl with Screaming Frog or Ahrefs, a ranking snapshot, a 1:1 redirect map for every old URL, a launch checklist, submission to Google Search Console and Bing, IndexNow. We typically migrate a marketing website with 10-30 pages in 3-6 weeks. The details are in website relaunch without losing SEO and on our website relaunch agency page.
Frequently asked questions
For B2B companies that run content as a system, a code system built on Next.js or Astro with Sanity. For design-led websites up to about 30 pages, with one or two languages and no programmatic pages, Webflow is enough. A builder only fits if the website should remain an extended legal notice and nobody does SEO.
Webflow wins on speed to launch and on the layout editor for non-technical people. Next.js wins as soon as you need per-request server rendering, integrations, login, or more than 20,000 CMS items. For pure marketing websites without app logic we tend to compare Webflow with Astro, because Astro builds statically and starts at 0 KB JavaScript for static content.
As soon as the website is meant to bring inquiries and you maintain more than a legal notice. Builders cost $17-159 per month per site but deliver no runnable export and no control over scripts, caching, or schema. We made that move ourselves in 2026, from Wix to Next.js and Sanity, with no stop in between.
Yes, via Sanity Presentation Mode: click the text in the live preview, the field opens, save, and the website rebuilds via webhook. At LeanWave this runs with 64 documents. What marketing does not change is the layout, and that protects the design for years.
Typically $0-20 per month: Sanity Free with 20 seats and 10,000 documents, Vercel Pro at $20 per developer seat including $20 usage credit. No fee per site, no surcharge per language. The cost block sits in development, not in the license, compared with $25-54 per site for Webflow Premium with localization.
Only if they are thin. Google demotes bulk pages without their own substance as doorway pages, and we have experienced that ourselves. What works are pages where every combination (industry, service, city) carries its own data, examples, and answers. The code system provides the structure, you have to provide the substance.
