What does StackOptic analyze?

StackOptic runs 18 analysis modules on any public website from a single URL. It detects 7,000+ technologies (CMS, frameworks, analytics, payments, CDN, hosting), evaluates SSL certificates and HTTP security headers with grades from A+ to F, measures Core Web Vitals (LCP, CLS, TBT, FCP), audits SEO meta tags and structured data, checks email security (SPF, DKIM, DMARC), analyzes AI & LLM readiness including bot access and llms.txt validation, extracts color palettes and typography, estimates carbon footprint, and generates permanent shareable reports.

Does it work on sites behind Cloudflare or bot protection?

Yes. StackOptic uses a real browser engine that loads pages exactly like a human visitor — executing JavaScript, rendering CSS, and handling redirects. This allows it to bypass Cloudflare, LiteSpeed, Sucuri, and other bot protection systems where traditional crawlers and HTTP-only tools fail.

What do I get on the free plan?

The free plan includes 5 analyses per day with access to all 18 modules, full scores, technology detection, and security grades. Every report is permanently accessible via a unique shareable URL — no login required to view. No credit card needed. AI-powered insights, re-analysis, PDF/JSON export, and comparison features are available on Pro ($24/mo) and Agency ($99/mo) plans.

What is AI & LLM readiness analysis?

This module evaluates how visible and citable your website is to AI search engines like ChatGPT, Perplexity, Google AI Overviews, and Claude. It audits access permissions for 8 major AI bots, validates llms.txt and llms-full.txt files, scores citation-ready content structure, and analyzes structured data (JSON-LD) for GEO readiness — helping you rank in the next generation of search.

How long does an analysis take?

Most analyses complete in under 10 seconds. StackOptic runs all 18 modules in parallel using a real browser session, so you get technology detection, security audit, performance metrics, SEO analysis, and AI readiness scoring simultaneously.

How accurate are the results?

Detection is based on real browser execution — DOM inspection, JavaScript runtime analysis, HTTP headers, and DNS records. With 7,000+ technology signatures and Lighthouse-calibrated performance scoring, StackOptic achieves high accuracy for mainstream technologies.

What security checks are performed?

The security module evaluates SSL/TLS certificates, 12+ HTTP security headers (HSTS, CSP, X-Frame-Options, Permissions-Policy, Referrer-Policy), HTTPS enforcement, and email authentication (SPF, DKIM, DMARC). Each site receives a letter grade from A+ to F with specific remediation steps.

Do you store the websites I analyze?

StackOptic only stores publicly available information that any visitor to a website would see — HTML content, HTTP headers, DNS records, and screenshots. We do not access private data, log in to websites, or perform any intrusive testing.

WP Rocket - Websites Using WP Rocket

What Is WP Rocket?

WP Rocket is a premium WordPress caching and performance optimization plugin used on over 3.5 million websites. Created by WP Media, WP Rocket is known for delivering significant performance improvements with minimal configuration, making it the most popular premium caching solution for WordPress.

Caching

WP Rocket generates static HTML files for WordPress pages, serving cached versions to visitors instead of processing PHP and database queries for each request. Cache preloading automatically generates cached versions of all pages. Separate mobile cache serves optimized content to mobile devices.

Performance Optimization

File Optimization minifies and combines CSS and JavaScript files, reducing the number of HTTP requests and total file size. Critical CSS generates above-the-fold CSS for each page, loading remaining styles asynchronously.

Lazy Loading defers loading of images, iframes, and videos until they enter the viewport. Database Optimization cleans post revisions, spam comments, transients, and other database bloat.

CDN Integration rewrites asset URLs to serve files from content delivery networks. Preloading supports DNS prefetching, preconnecting to external domains, and font preloading for faster resource loading.

Ease of Use

WP Rocket requires no technical knowledge to configure. Activating the plugin immediately applies caching and basic optimizations. Advanced options are clearly documented with explanations of what each setting does.

Why Choose WP Rocket

WordPress site owners wanting significant performance improvements without technical complexity choose WP Rocket. The combination of page caching, file optimization, lazy loading, and database cleanup in a single, user-friendly plugin consistently delivers measurable performance gains.
