Implementing the French Government Design System in Wagtail
2025-10-08 , Main

Discover how Sites Faciles help French public administration build accessible, ready-to-use websites with the French Design System—no tech team or contractors required.


Sites Faciles is a project developed by the French government’s digital services suite, aimed at helping public servants quickly create websites using the official French Government Design System (DSFR), currently used on about 80 websites.

The goal: provide an accessible, user-friendly CMS that doesn’t require an internal tech team or costly external contractors for each new website.

Wagtail’s StreamFields made it possible to implement more than 40 DSFR components as reusable blocks. But this approach also brought challenges: offering layout templates is not straightforward, and the editing interface can become complex when components themselves are complex.

In this talk, Lucie Laporte and Sylvain Boissel—two of the three developers behind Sites Faciles – will share how the project has evolved over the past two years, the lessons learned, and the issues they are now tackling in designing a simpler admin experience.

I'm a freelance web developer, working mostly with Django (for about 10 years now) and Wagtail (since 2020). I currently work on Sites Faciles for the French government’s digital services suite

I'm a freelance web developer since 2021. Before turning to tech, I spent years as an art registrar, more used to wandering through museum storage rooms than reading lines of code. Since my career change, I've been working extensively with Wagtail and Django, and I currently contribute to Sites Faciles, a platform for the French government. That journey from art handling to web development has shaped the way I approach projects today—with a mix of creativity, precision, and care.
