Astro

- Ships zero JS by default — fastest page loads compared to Next.js or Docusaurus - Best Core Web Vitals scores out of the box (LCP, CLS, INP) - Content-first architecture with island hydration — only loads JS where interactivity is needed - Framework-agnostic: can use React, Vue, or Svelte components within the same project - Built-in Markdown/MDX support ideal for content-heavy sites - Simpler than Next.js for static/content sites without the overhead of a full React framework

We build content-heavy sites — docs, a spec reader, marketing — so static-first output mattered more than a JS runtime. Astro ships zero JavaScript by default and lets us drop in Svelte islands only where we actually need interactivity, so pages stay fast. Content Collections with typed schemas turned multilingual parity into a build-time check instead of a review worry. And because it's just a codebase, our agents can read it, run it, and open PRs against it like any engineer would — which is the whole point for us.

Astro's island architecture let me ship a heavy React canvas app with near-zero JS on static pages. SSR + client:only on the interactive components meant fast loads without sacrificing the real-time simulation features. Easiest framework I've used for mixing static marketing pages with a full SPA workspace

Our docs site runs on Astro while the main app is Next.js. Docs did not need a server, they needed fast plain content pages: MDX collections in git, near zero JavaScript shipped to readers, builds in seconds. Writers edit markdown, CI ships static files, and there is nothing to maintain.
