When a website becomes
a lead generation asset.
A custom website is no longer just about showcasing a business. It clarifies the offering, reassures prospects, supports SEO and GEO, connects the right tools, and gives teams a truly usable CMS to publish without waiting for technical changes.

03 — Why ScrollThe speed of AI,
The speed of AI,
the accountability of an agency.
Moving fast doesn’t mean cutting corners, and a beautiful website isn’t enough. Here’s what actually changes when Scroll handles your site.
01
We develop fast, without cutting corners.
AI agents and proven components to move fast; clean, versioned, tested code, and real accountability for the outcome. Not just a pretty prototype that collapses in production.
02
Your site remains yours.
Documented code, controlled data, a CMS your team or another provider can take over. A clean content base, usable by AI agents, and a project transferred to your account upon delivery. No black box, no forced dependency.
03
We choose the tool with you, not for you.
No technological dogma. We recommend what serves your project (Webflow, Payload + Next.js, or custom), and we’ll tell you honestly when there’s no need to overcomplicate things.
04
The same people, from scoping to launch, and beyond.
Senior profiles, founders involved in every project, with no outsourcing or handoffs. And we stay on after launch: maintenance, updates, SEO.
04 — Our method
Scope first, design later.
Six steps, delivered as artifacts: sitemap, SEO plan, wireframes, content model, components, acceptance testing, and editor guide. We don’t launch a site without understanding the audience, content, and SEO constraints.
01 — Scope
Scope the site before designing it
Goals, targets, messaging, content, SEO constraints, integrations, and success criteria.
02 — Structure
Structure content and journeys
Sitemap, priority pages, templates, CTAs, forms, and internal linking.
03 — Design
Design the page system
Reusable components to let the site grow without losing consistency.
04 — Develop
Develop the site and CMS
Frontend, back-office, content models, SEO fields, media, forms, and integrations.
05 — Prepare
Prepare for production
Content, technical SEO, tracking, redirects, performance, backups, and access.
06 — Evolve
Train and evolve
CMS documentation, team training, maintenance, and planned evolutions.
05 — Choosing the right stack
You come with a need, not a stack to choose.
Our role is to understand your project, content, team, and constraints, then recommend the right approach: Payload + Next.js, Webflow, progressive migration, or a custom stack. The technical choice serves the site—not the other way around.
Payload + Next.js is often our top recommendation for ambitious sites: structured content, tailored back-office, versioned code, AI integration, and full scalability. Webflow remains an excellent choice for marketing and corporate sites when visual editing, lightweight maintenance, and fast deployment are top priorities.
06 — Compose & evolve your pagesYour teams compose and publish,
Your teams compose and publish,
without depending on us.
The challenge isn’t the tool, but autonomy: your teams compose their pages using ready-to-use components, publish them, and evolve them without developers, within a framework that safeguards design and SEO. And when needed, AI assistance speeds up production—without replacing human review.
● Real capability, delivered
The manual page builder
- Create a page from the back-office by selecting its sections.
- Fill each section with your content, without touching the code.
- Reorder or remove sections as needed.
- Publish the page via a slug (e.g., /landing-page).
- Maintain a framework that protects the design and consistency of the site.

○ Depending on the project · optional
AI assistance, as an add-on
In addition to the manual builder, we develop AI assistance features that we activate only if they’re in scope or taken as an option: SEO and content suggestions field by field, or a full page draft from a brief.
These aren’t off-the-shelf products. AI suggests, the team validates. It doesn’t replace scoping, strategy, or validation: it speeds up production within a framework managed by the team, under human supervision.

07 — BudgetHow much does
How much does
a custom website cost?
The cost of a custom website depends on scope, not a one-size-fits-all package. We don’t share pricing before understanding the project: a simple showcase site and an editorial site with a custom CMS don’t have the same budget. The most reliable approach is to start with scoping, then an estimate.

Frequently asked questions
The most common questions we get during scoping. If yours isn’t here, reach out!
A custom website with a CMS is a site whose design and content model are tailored to your business, with a back-office that allows your teams to publish and update pages without a developer. It stands out from a generic template with its structure designed for your content, SEO, and integrations.
Webflow is relevant when visual editing, speed of launch, ecosystem, and lightweight maintenance are priorities. Payload becomes more compelling when the project requires a custom CMS, structured content, versioned code, advanced integrations, or an AI page generator. A detailed comparison is available on the Agence Webflow and Agence Payload pages.
No. You can come with a need for site creation or redesign, not a technical solution. We recommend the stack based on context: project maturity, team, budget, SEO/GEO constraints, autonomy needs, and planned evolutions. Webflow, Payload, and other options remain possible depending on the project.
Yes, it’s a core goal of our approach. We structure the CMS so they can edit content, compose and publish pages, manage media, and fill in SEO fields without touching the code.
Yes. We audit the existing site, retain what works, rebuild what limits the project, and prepare a controlled migration when necessary. For a Webflow to Payload case, see the Migration Webflow vers Payload page.
SEO is addressed from the scoping phase: site architecture, search intent, metadata, internal linking, performance, structured data if relevant, URL redirects in case of changes, and Search Console monitoring post-launch. We also consider GEO—ensuring the site is understood and referenced by search engines and AI-generated responses.
Yes. With Payload, the CMS can enable you to build pages from predefined sections (Hero, Portfolio, Services, FAQ, Gallery, CTA, rich text), then publish them via their slug. We can also implement an AI-assisted page generator using pre-validated components, with human review before publication.
It depends on the number of pages, design complexity, CMS, integrations, content volume, and SEO constraints. For an ambitious project, we scope it first to provide a reliable timeline.
Yes. Maintenance, updates, technical monitoring, SEO optimizations, and team support after launch. The level of maintenance is tailored to the project.
