Show HN: Flipsite – Website builder for 100% Lighthouse scores

Hi HN,

We’ve been building Flipsite, a website builder where Lighthouse 100% scores aren’t a nice-to-have — they’re the foundation.

Why we built it: Every other website builder we tried was “builder-first, HTML/CSS second.” That means bloated DOMs (nested <div>s inside <div>s), render-blocking scripts, unused CSS, and SEO headaches. We flipped the model:

Built the compiler first — it generates clean HTML, critical CSS, no third-party libraries, and optimizes for speed, accessibility, and technical SEO.

Then layered on a Framer-like editor for design. Not our first rodeo, but it was hard work.

What’s working today: - Clean HTML output (no nested <div> soup)

- Automatic critical CSS

- Zero render-blocking scripts or unnecessary libraries

- Free forever: 1 website, unlimited CMS items & collections (https://flipsite.io/pricing/)

- Export everything as a ZIP to deploy anywhere

Coming before launch (1–2 months):

1) Automatic deployment to GitHub Pages, Cloudflare Pages, etc.

2) More and better templates to help you get started

3) Whatever you tell us is essential ;)

We’d love early feedback — especially from developers and designers who care about performance, accessibility, and SEO from day one.
