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.

Bulma - Websites Using Bulma

What Is Bulma?

Bulma is a modern CSS framework based on Flexbox with no JavaScript dependencies. Created by Jeremy Thomas, Bulma provides a clean, readable class system for building responsive websites using only CSS. Its modular architecture allows importing only the components needed.

Pure CSS

Bulma is purely CSS with zero JavaScript. Interactive behavior must be implemented separately, giving developers freedom to use any JavaScript framework or vanilla JS. This approach keeps the framework lightweight and avoids conflicts with application JavaScript.

Flexbox Grid

The responsive grid system uses Flexbox for powerful layout capabilities. Columns automatically adjust based on content and available space. Responsive helpers control visibility and sizing at different breakpoints.

Components and Elements

Bulma includes buttons, forms, cards, media objects, tiles, modals, navbars, dropdowns, panels, tabs, breadcrumbs, pagination, messages, tags, and progress bars. All components use a consistent BEM-inspired naming convention.

Why Choose Bulma

Developers wanting a clean, CSS-only framework without JavaScript opinions choose Bulma. Its readable class names, Flexbox foundation, and modular architecture make it straightforward to learn and integrate with any JavaScript stack.
