Pagefind
Static-site search, zero infra
FreeSearch, vector & RAGpagefind.app
What it is
A Rust CLI that crawls your built HTML after a static site generator runs, then writes a chunked search index and JS bundle into your output folder. Browsers fetch only the chunks a query needs — full-text search across a 10,000 page site in under 300kB of total payload.
Why it earns a slot
Zero backend, zero API key, zero monthly bill. Point it at
dist/ and you have working site search with prebuilt UI web components — ideal for Astro, Hugo, Eleventy or a Next static export.Know before you commit
It only indexes what is in your built HTML. Client-rendered content, authenticated pages and data fetched at runtime are invisible to it.
Getting started
npx pagefind --site dist

How Pagefind sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
