Custom websites, coded to last.

We build brochure websites and custom websites: fast, easy to update, and built to be found on Google. We code them and hand them over with their documentation.

Target load time under one second, measured at delivery.

Context

Why your website's code matters

A slow website costs you traffic. A badly coded one costs you time and money to maintain. We deliver clean, documented code that is easy to pick up, whether you do it yourself or with another team.

What we hear

What website owners tell us

Your website takes several seconds to load. Your provider takes three weeks to change one line of text. You inherited a patched-up WordPress site that nobody really understands.

What we deliver

What your website gets

  • A website that is fast on mobile

    Next.js App Router, optimised images, lazy loading, a CDN: your website loads quickly everywhere, including on a phone.

  • Code that is easy to pick up

    Strict TypeScript, documented components, unit tests: your codebase is readable and easy to evolve.

  • Security checked before launch

    Supabase authentication, secure environment variables, correct HTTP headers: we do not discover the gaps in production.

  • Continuous deployment

    On Vercel or your own host: every release is automatic, tested and reversible.

Before the quote

What we look at before pricing

The first call is about your customers. Who comes to your website, on which phone, and to do what first? A tradesperson waiting for quote requests does not need the same website as a firm that is hiring or a restaurant taking bookings. The answer decides almost everything else, from the number of pages to where the contact button goes.

If you already have a website, we open it together during the call. We look at what Google knows about it in Search Console: the pages that get visits and the ones that get none. A page that has brought you customers for years stays, with its words and its address. If that address has to change, we redirect it properly so nothing is lost.

Then comes the content question, which we always ask before giving a date. Who writes the text, who supplies the photos, and who will update them in six months? A website delivered without its text sits waiting, sometimes for weeks, and the budget waits with it. We would rather know early, even if it means helping you write the pages that matter most.

The technical choice

When a custom website is worth it

Sometimes a ready-made website builder is the right answer, and we tell you on the first call. A five-page website that changes twice a year does not need more. You save the budget for something else, and we are still here the day your needs grow.

A custom website becomes useful when your website has to do something specific. A form that sorts requests, a client area, a catalogue you can filter, content that comes from another tool. With a generic theme, you then spend your time working around it, and every workaround makes the page heavier. The next change costs more, then the one after that.

We code with Next.js and TypeScript, the same tools we use for our own website. Pages are prepared in advance when possible, so they are served fast, even on an average mobile network. If you want to edit your text and images yourself, we build a custom admin interface, and you never have to touch the code. And when a project calls for a 3D scene or a detailed animation, Guillaume builds it: he also comes from 3D modelling and video games.

At delivery

What is yours at delivery

The code, the domain name and the hosting are in your name: at delivery, the website belongs to you. We work directly in your accounts, with access you can remove at any time. If you change provider one day, there is nothing to ask us for and nobody to wait for.

The code comes with its documentation: how to run the website, how to add a page, where the settings are. William and Guillaume write it for someone who was not there during the project. Often that someone is you, a year later, adding a new offer. Sometimes it is the developer you hired in the meantime.

After launch, the website keeps evolving, and that is where custom work pays off. A new page, a reworked form or an added section does not mean starting over. Fixes and changes are quoted as needed.

The method

How a custom website gets built

  1. Architecture and technical choices

    We start by choosing the stack your real needs call for. No over-engineering, no underestimating.

  2. Development in increments

    We deliver working pieces as we go. You can test them and give feedback before the final delivery.

  3. Tests and code review

    Unit tests, integration tests, manual review: we do not deliver code we have not tested ourselves.

  4. Launch and handover

    Deployment on Vercel or your host, technical documentation, handover to your team if needed.

Questions

Website development questions

How much does a brochure website cost?

A custom brochure website starts at €3,500, for up to five pages. A fully custom website, with more pages or specific features (client area, filterable catalogue, a form that sorts requests), is between €6,500 and €12,000. The fixed price follows the call, in writing.

How much does a website redesign cost?

The same price list applies, from €3,500. What changes the price is what we keep. Before pricing, we look in Search Console at the pages that bring you visits: we keep them, or redirect them to their new address so you do not lose the rankings you have earned.

Should I build my website myself or hire an agency?

For a website of a few pages that rarely changes, a builder like Wix is often enough, and we tell you on the first call. Hiring a team becomes useful when the website has to do something specific, rank well from the start, or when you do not have time to run it. With us, the code, the domain name and the hosting stay in your name.

Do I need a specification to build a website?

No, you do not need to arrive with a document. We cover it on the 30-minute call: your customers, what they come to the website for, the content you already have. You then get a written proposal, with the scope and the price. It serves as your specification.

How much does website maintenance cost?

Fixes and changes are quoted as needed. The code is documented and it is yours: you can also hand those changes to someone else.

Can you take over an existing website?

Yes, as long as we can run a technical audit first. We need to understand the state of the code before committing to a timeline.
