Footprint

What this site does to weigh as little as possible, in the spirit of /green pages.

A visit to the home page emits about 0.01 g (A+) of CO₂, according to the Sustainable Web Design model of the Green Web Foundation (CO2.js). The measurement is taken again every morning on the production site.

  • Static pages: nothing is computed on a visit, everything is generated once at build time.
  • Very little JavaScript, no framework, and the site works without it.
  • Native CSS, inlined in the page: no extra request.
  • Images converted to AVIF and WebP, at the displayed size.
  • Fonts served from the site, with no call to a third party.
  • No tracker or third-party script, apart from audience measurement without cookies.

The technical details are under the hood.
