Custom website design and build

A custom website is code written for your brand, not an adapted theme.

Building a custom website means designing and coding a site from your brand and your goals, with no template or off-the-shelf theme: showcase site, premium site, site with a client area or online booking. OTTOPILOTE builds these sites for companies, practices and brands, in France and the United States.

Under the surface.

The difference with a WordPress or Wix site lies under the surface: a design drawn for you rather than a repurposed theme, lightweight code that loads fast and ranks well, content that sits in the HTML, readable by Google and by AI answer engines alike. A light CMS lets you edit your text without us.

When it makes sense.

A custom site is justified when first impressions matter (consulting, healthcare, real estate, industry, luxury), when the site must do something (quotes, booking, client area, connected catalogue) or when the current site no longer converts. For a simple temporary presence, a no-code tool is enough, and we will tell you.

Our commitments.

Our published commitments: for a showcase site, a Lighthouse score of 95 or above and one to two weeks of lead time, hosting and domain name included for the first year. The home page of the site you are reading, measured on 2 October 2026 with the mobile profile (median of three runs): 96, for 412 KB transferred. When a feature costs speed, a full-screen video or an interactive map, we tell you before adding it.

What we build

Four kinds of sites we build most often.

From a practice’s showcase site to a brand site with booking.

Showcase

The premium showcase site

Present the business, the team, the offer, and convert: quote request, booking, call. The site of Thomas Tirache’s practice, a midwife sonographer, shipped in one to two weeks, with Doctolib booking built in.

Why OTTOPILOTE

What we check on every site, because we learned it shipping our own.

Links Google can follow.

On a site we had delivered, the menu and footer were JavaScript buttons: Google does not follow them, and 9 pages stayed “discovered, currently not indexed”. Fixed in September 2026. Since then, every navigation link is a real link, checked before go-live.

The first visitor, measured.

On our own home page, in September 2026, the slowest element for a first-time visitor was the cookie banner, loaded after every script. Moved to the top of the page: the main content now paints in 2.95 s instead of 3.59 s (mobile Lighthouse, median of seven runs).

Images at the right weight.

The original photos of a site we delivered weighed 11.6 MB. Served as 1,200-pixel WebP by the host’s image optimiser: 273 KB, checked on 1 October 2026.

Text you can read over a photo.

On the hero image of a site we delivered, the white heading only reached a 2.31:1 contrast ratio, below accessibility thresholds. Fixed without touching the image: 4.75:1 on desktop, 5.17:1 on mobile (13 September 2026).

Analytics wait for consent.

Even in “consent denied” mode, the Google Analytics script sends requests to Google: we saw it on our own site in August 2026. So our sites do not load that script until the visitor accepts.

The code is assigned to you in writing.

Source code handed over at delivery, once the project is paid; hosting in your name. You can leave with the site.

Showcase site · Medical practice

A medical practice online in one to two weeks, booking included.

The problem
A midwife sonographer with no online presence: no showcase for the practice and the care pathway, and no simple booking for patients.
What we built
A modern, reassuring showcase site: pathway, examinations, practice and fees presented clearly, with online booking built in via Doctolib.
The result
Site delivered in one to two weeks, with online booking via Doctolib. The practice has a showcase in its own image, open around the clock.

Frequently asked questions

What we get asked before signing.

Another question? Write to us: a human reply within one business day.

What is the difference between a custom site and a template site?

A template is a generic theme you adapt: same structures, same plugins, same limits as thousands of other sites. A custom site is designed then coded for your brand and your goals: unique design, lightweight code, no plugins to maintain, and a structure built for search from the start.

How much does a custom website cost?

From €500 to €5,000 for a showcase site depending on pages, design and content to produce, €3,000 to €15,000 for e-commerce, and €10,000 to €40,000 when the site includes a client area or a tool. At OTTOPILOTE, the website plan starts at €600, with hosting and domain included for the first year.

How long does it take to build a custom showcase site?

One to two weeks for a showcase site, from brief to go-live, if your content is ready. Thomas Tirache’s practice site shipped within that window. A site with a client area or booking is closer to a web application timeline, six to eight weeks.

Is a custom site necessarily more expensive than a template?

At build time, a well-chosen template costs less. Over time, a coded site has no builder subscription, no paid plugins, no forced redesign when the theme is abandoned, and it ranks better. Compare over five years, hosting and maintenance included.

Will I be able to edit the site myself?

Yes. A light CMS lets you edit text, images, news and pages without technical skills. Anything touching structure or design stays in the code, so the site keeps its performance and consistency.

Showcase site or e-commerce site, what is the difference?

A showcase site presents and gets people in touch: quotes, appointments, calls. An e-commerce site sells online: catalogue, cart, payment, delivery, and the obligations that come with it. The second needs more pages, more integrations and more maintenance.

Is SEO included in the website build?

Technical SEO, yes: heading structure, tags, structured data, sitemap, performance, redirects in case of a redesign. Ongoing SEO (regular content, authority) is a separate service, offered on our SEO page.

Will my site be readable by ChatGPT and AI answer engines?

Yes, on one condition that is often missed: the content has to be in the HTML sent by the server, not added afterwards by JavaScript. On a site we had delivered, an animated counter started from zero: until 29 September 2026, the HTML showed “0%” instead of a key figure of the offer. Google read the right value once the script ran; most AI crawlers do not run JavaScript (Vercel, December 2024) and read 0%. For Google, no special file such as llms.txt and no chunking of the text is needed, as its July 2026 guide says: clear HTML, real links and useful content are enough. This very site appeared 1,040 times in Google’s generative AI features (AI Overviews, AI Mode) over the last three months, according to Search Console (checked on 2 October 2026).

What do I need to provide to get started?

A brief of a few sentences, your logo and brand guidelines if they exist, your text or the material to write it, a few sites you like, and access to your domain name if you have one. The rest we ask for as the project goes.

Should I redo my site or improve it?

Redo when the structure no longer keeps up: outdated technology, slowness, poor mobile experience, security, a business that has changed. Improve when the site holds up but converts poorly: content, calls to action, speed. Our guide “Website redesign: how to know when it is time” lists the signals.
