What PageSpeed issues can be fixed with server config?

Cache-Control headers, text compression (gzip/brotli), image optimization settings, and CDN configuration can all be fixed at the server level.

Why does my PageSpeed score vary between runs?

PSI measures real user conditions and lab data — results can vary based on server load, network conditions, and third-party scripts.

Does SpeedFixer work for WordPress sites?

Yes — SpeedFixer detects WordPress and generates WP Rocket / LiteSpeed Cache plugin settings instead of server config blocks.

Paste your URL. SpeedFixer fetches your live PageSpeed audit and generates stack-specific server config — for Nginx, Cloudflare, Vercel, Apache, Netlify, and WordPress.

About SpeedFixer

What does SpeedFixer check?

SpeedFixer calls the Google PageSpeed Insights API with your URL and retrieves the live audit results for your site. It then generates stack-specific server configuration based on your detected stack — Nginx, Apache, Cloudflare, Vercel, Netlify, or WordPress.

What is the difference between server config fixes and code-level fixes?

Server config fixes are changes to your web server or CDN configuration — cache headers, compression, HTTP/2 push. Code-level fixes require changes to your application code or build pipeline — unused JavaScript, image formats, bundle splitting. SpeedFixer separates these two categories clearly.

How does stack detection work?

SpeedFixer reads ther response header and CDN-specific headers (Cf-Ray for Cloudflare, X-Vercel-ID for Vercel, X-NF-Request-ID for Netlify) to identify your stack. You can override the detected stack if your server is behind a proxy that masks these headers.

Is my URL stored or logged?

No. The PageSpeed API call is made via a stateless Cloudflare Worker. Your URL is not stored or associated with any account.
