Features

Every optimization,

one pipeline.

pageflare applies 30+ optimizations to your static site output. Here's everything it does.

Performance

Speed where it matters

Critical CSS Extraction

Inlines above-the-fold CSS, defers the rest. Eliminates render-blocking stylesheets for instant first paint.

JS Defer & Minification

Automatic defer and loader injection for non-critical scripts. Minification reduces payload size.

Content Hashing

Fingerprinted filenames with optimal cache headers. Immutable assets, forever cached by CDNs.

Speculation Rules

Injects speculation rules for instant page navigations. Near-zero latency transitions between pages.

Background Image Deferral

Defers off-screen CSS background images using IntersectionObserver. Reduces initial page weight.

Preconnect Hints

Automatically injects preconnect and dns-prefetch hints for third-party origins detected on the page.

Images

Pixel-perfect delivery

Smart Image Optimization

Lazy-loading, dimension inference, responsive srcset generation, and adaptive sizing — zero config.

Build-Time Image Processing

Format conversion to WebP/AVIF, responsive srcset variants, disk caching, and content deduplication.

Platform Image CDN

Rewrites images to use Vercel, Netlify, or Cloudflare Pages image CDN for on-the-fly format conversion.

YouTube Facade

Replaces YouTube embeds with lightweight facades. Saves 500kb+ per embed until the user clicks play.

SVG Optimization

Inline SVGs are optimized automatically — removes editor metadata, comments, and redundant attributes.

Fonts

Typography, optimized

Google Fonts Self-Hosting

Downloads and self-hosts Google Fonts. Eliminates third-party requests and improves load times.

Font Subsetting

Unicode-range subsetting strips unused glyphs. Reduces font payloads by 60-80%.

Font Fallback Stacks

Metric-adjusted fallback fonts for 30 popular Google Fonts families. Eliminates layout shift while web fonts load.

Font Display Swap

Injects font-display: swap into all @font-face rules so text remains visible while custom fonts load.

SEO & Crawlers
