La Petite Vitrine

Freelancers, small outfits and artisans need a clean, professional online presence — but they get stuck between two extremes: the custom-built site, too slow and too expensive, and the DIY builder, time-consuming and quickly botched. Both share the same blind spot: you pay before knowing what the result will look like. La Petite Vitrine was born from that gap — to offer a third path, simple and guided, where you see the finished site before you buy.

I designed and built La Petite Vitrine, a platform that industrializes the creation of small profession-based sites. The business principle fits in one sentence: what you buy is what you see. The catalogue doesn't show mock-ups but finished, working landing pages, generated with AI and then audited; the client browses, picks the one that fits their profession (health, retail, services, wellness, leisure), I integrate their content, and the site goes live after validation. Every site follows a clear, proven structure: introduction, offering, practical info, contact, legal notices.

The tech choice follows the business model: to sell a €650 go-live and a €14/month subscription, each site has to cost next to nothing to produce, host and maintain. Neither one WordPress per client (an instance to maintain and secure for every site) nor a no-code builder (a subscription per site, locked-in content) could hold that equation. So I built a custom Next.js platform (React, TypeScript, Tailwind) around one simple contract: every theme in the catalogue is a self-contained static preview fed by JSON content, and client sites ship as static exports — fast, secure, nearly free to host. Edited content lives on Vercel Blob (the serverless filesystem is ephemeral). GDPR by default: no advertising, no trackers.

AI is what makes this model possible: hand-building about fifty finished, browsable landing pages — 12 active at launch — could never sell at this price. Yet the generation is anything but improvised: development relies on Claude Code, framed by a project constitution (architecture, contracts, security rules) and ten specialized agents — theme integration, security, performance and UI/UX audits, Playwright functional tests, content ↔ schema ↔ DOM consistency. No theme ships without passing the audit scripts that act as gates. AI generates and accelerates; the architecture, the contracts and the quality bar remain human decisions — that is what keeps the product maintainable.

The result is a clear, no-surprise offer: €650 excl. VAT to go live (integration included), then from €14 excl. VAT/month for hosting and maintenance, with payment after scoping. A pilot programme of 10 projects (5 mental-health practices, 5 artisan workshops) documents the service with real, usable examples rather than promotional mock-ups.
