Every kilobyte of JavaScript is a tax on someone’s battery, someone’s data plan, someone’s low-end phone — often in Sylhet, often on 3G. Nakshora’s answer is absolute: the framework ships CSS, and nothing else.

What zero-runtime buys#

  • No hydration — pages are interactive at first paint.
  • No supply chain — the core compiler has zero runtime dependencies.
  • No lock-in — the output is plain CSS; leave whenever you like (MIT).
  • Honest budgets — performance budgets (performance budgets) stay about *your* code.

Even the docs obey#

This platform is pre-rendered HTML; its small React island only enhances search and theme. Without JavaScript, every word still renders — the doctrine demands it.

Tip. Measure it yourself: performance numbers from CI, pinned by doc-claims tests.
