The whole site is plain HTML rendered at build time. No client framework, no trackers, no chart library: the activity, language and benchmark charts are SVG generated from JSON when the site builds.
The interactive layer is a few kilobytes of vanilla JavaScript: the ⌘K palette and search, the light and dark toggle (it follows your system until you choose), the sun and moon in the hero that track your local time, count-ups, and the links dock in the corner.
The full colophon, with reasons, is in How this site is built.
