littlewebsite.co is running on Astro, pulling content from Sanity content management system and delivering the site statically. It uses view transitions to make it feel like a SPA (single page app) but is in fact a MPA (multi page app) that works pretty well without javascript.
littlewebsite.co is running on sustainable energy via Cloudflare and is cleaner than 94% of all web pages globally (I would wager it’s higher than that as it’s being delivered by CDN and not an always-on server).
