If you're choosing a platform for your SaaS marketing website in 2026, there are three real options: custom code, Webflow, and Framer. Everything else — WordPress, Wix, Squarespace — is out, for reasons we'll cover quickly.
A bit of context: we published an earlier version of this article in 2025, and it reached the opposite conclusion. Back then we recommended Webflow for almost every B2B SaaS marketing site, because the alternative — custom code — meant hiring developers, waiting on sprints, and paying an ongoing tax on every landing page and copy tweak. That was the right call for that era.
The era is over. AI coding assistants — Claude in particular — got good enough that the entire cost side of the custom-code equation collapsed. We rebuilt our own site custom, we build client sites custom, and we're updating our public position to match.
The short version:
Custom code with Claude is now the right choice for most B2B SaaS marketing sites. It's faster to build than a Webflow project, dramatically more performant, integrates with your product in ways no builder can, and removes the design ceiling entirely.
Webflow is still a good tool — the best of the visual builders — and the right choice when nobody on your team will ever open a code editor. But it's no longer the default. You now pay its platform ceiling without getting the time savings that used to justify it.
Framer remains what it was: great for portfolios and quick landing pages, not built for SaaS marketing sites with real content and integration needs.
Why WordPress, Wix, and Squarespace are still out
Nothing has changed here, so we'll keep it short. WordPress is the worst of all worlds for SaaS: hard to design in, easy to break, a plugin-security treadmill, and slow unless you fight it constantly. Wix and Squarespace are built for restaurants and creators — they lack the design flexibility and the integration surface a SaaS marketing site needs.
Skip all three. The real 2026 decision is custom code vs. Webflow, with Framer as a niche option.
Custom code with Claude: the new default
The old case against custom code was never about the output — everyone agreed a well-built custom site was the best possible artifact. The case against it was cost: developer time, slow iteration, and a marketing team stuck filing tickets to change a headline.
Claude deleted that case. Here's what the workflow actually looks like now, and why it wins on every axis that used to favor builders.
Faster to build — yes, faster than Webflow
This is the part that surprises people. A skilled Webflow developer assembles a section in hours. Claude writes the same section — production React, your design tokens, responsive, accessible — in minutes, and iterates on feedback in seconds. New landing page variants, programmatic SEO templates, a pricing page rework: things that used to be a sprint are now an afternoon.
The catch used to be "but someone has to review and deploy it." With preview deployments on Vercel, every change gets a shareable URL before it ships. The review loop is tighter than a Webflow staging flow, not looser.
More performant, by a wide margin
A static Next.js site serves pre-rendered HTML from a CDN with no builder runtime attached. No render-blocking platform scripts, no class-soup CSS you didn't write, no JavaScript you can't remove. Perfect-or-near-perfect Core Web Vitals are the baseline, not an optimization project.
This matters more than it used to. Page speed is a ranking input, but more importantly it's a conversion input — and when every competitor's site is built on the same builder templates, loading instantly is a felt difference.
Easier to integrate with your product
This was always custom code's trump card, and it's the one builders structurally cannot match. Your marketing site is code, sitting next to your product's code. That means:
- Live product data on marketing pages — real counts, real screenshots, real templates pulled from your API
- Interactive tools as native pages: calculators, ROI estimators, graders, free tools that earn links
- Programmatic SEO at any scale, generated from your actual data instead of a CMS workaround
- Signup, auth, and trial flows that share logic with your app instead of approximating it
On a builder, each of these is a hack, an embed, or a "not possible." In a codebase, they're a prompt.
Increased design potential
Builders give you a palette of primitives and a ceiling you eventually hit. Code has no ceiling. Custom interactions, scroll-driven scenes, WebGL, animation systems tuned to your brand — if you can describe it, Claude can build it, and a design-literate reviewer can polish it.
The practical effect: your site stops looking like a theme. In a market where every SaaS homepage is the same three-column template, that's positioning, not decoration.
The honest trade-offs
Custom code in 2026 still isn't free. Be clear-eyed about what it requires:
- Someone technical-adjacent has to own the repo. Claude writes the code, but a human approves it, manages deploys, and keeps the guardrails. This can be one fractional person or a partner — it no longer needs to be your product engineering team.
- Content editing needs a CMS. Pair the codebase with a headless CMS like Sanity and marketers edit content visually, without touching code. Skipping this step is how custom sites used to rot; don't skip it.
- AI output needs taste. Claude will happily build something mediocre if you let it. The teams getting standout results give it a real design system and review like editors, not spectators.
Webflow: still good, no longer the default
Everything we said about Webflow in 2025 remains true. Clean HTML, real CSS control, a strong CMS, and a visual canvas that designers genuinely like. If your team has zero appetite for a codebase — no technical marketer, no fractional help, no agency partner — Webflow is still the best place to land, and it beats Framer for serious marketing sites.
What changed is the comparison. Webflow's pitch was "ninety percent of custom quality without the custom cost." When the custom cost was developer-weeks, that trade was obviously right. Now that the custom cost is a Claude subscription and a review process, you're left paying Webflow's ceiling — the integration wall, the platform lock-in, the performance overhead, the per-seat pricing — without the savings that justified it.
Choose it deliberately, not by default.
Framer: same verdict as before
Framer is fast and beautiful for what it's for: portfolios, single landing pages, design-forward microsites. It still isn't built for content-heavy SaaS marketing sites — the CMS is thin, SEO controls are limited, and the integration story is weaker than Webflow's, let alone code. If you're a designer shipping a launch page this week, use it. Otherwise, no.
How to choose in 2026
The bowling-lane analogy from our original article still works, with one update. Builders are bumper lanes: they keep the ball out of the gutter and cap how good your throw can be. Custom code used to mean bowling without bumpers — high ceiling, lots of gutter balls, expensive coaching. Claude didn't remove the bumpers; it gave you a professional bowler who throws for you while you call the shots.
So the question is no longer "do we have engineers to spare?" It's:
- Can anyone in your orbit own a repo — a technical founder, a growth engineer, a fractional partner? Go custom. The output ceiling is higher on every axis and the cost premium is gone.
- Truly nobody? Use Webflow, and accept the ceiling consciously.
- Shipping a portfolio or one-off launch page? Framer.
Your engineering team still shouldn't build it
This advice survives the AI shift, with a twist. The old problem was that marketing sites died in the product backlog — every headline change waited behind feature work. That problem is gone: with Claude plus a CMS, the marketing team can ship daily without borrowing engineers.
The twist is that the failure mode moved. The risk now isn't speed; it's ownership. A marketing site needs someone accountable for conversion, message, and craft — not just someone who can merge a PR. Treat the site as a marketing asset that happens to be code, not an engineering asset that happens to have copy.
Frequently asked questions
Is custom code good for SEO?
It's the best option, full stop. Total control over rendering, structured data, internal linking, page speed, and programmatic page generation. Builders approximate this; code is this.
Is Webflow still worth using in 2026?
Yes, in one situation: no one on your team will ever touch a codebase and you don't want a partner who will. Webflow remains far better than WordPress, Wix, Squarespace, and Framer for SaaS marketing sites. It's simply no longer the automatic recommendation.
Can Claude really build a production marketing site?
Yes — this site is the proof we point to. The honest caveat: quality tracks the inputs. A real design system, a human reviewing output, and preview deployments before anything ships. Claude is the builder, not the owner.
What stack should a SaaS marketing site use?
Our default: Next.js, Astro, or similar with Tailwind, Sanity as the headless CMS so marketers edit content visually, and Vercel for hosting and preview deployments. Boring, proven, and fast.
How do marketers edit content on a custom site?
Through the CMS, visually — the same way they would in Webflow's editor. The difference is what's behind it: pages assembled in code with no platform ceiling, instead of a builder canvas. Or going straight into a chat with Claude.
When should I migrate from Webflow or WordPress to custom code?
When you hit the ceiling: an integration the platform can't do, a programmatic SEO play it can't scale to, performance you can't squeeze out, or a design direction it can't express. Migrate the highest-leverage pages first — you don't need a big-bang rebuild.
