# Site Stack Detector

> See what framework, libraries, and analytics any website is running on.

Site Stack identifies the tech behind any website — frameworks, UI libraries, analytics, payment processors, fonts, hosting — in a clean, scannable panel.

## Benefits

- Identify the framework, UI library, and CMS a site uses
- Detect analytics, A/B testing, and tracking tools at a glance
- See payment, auth, and CDN providers without DevTools spelunking
- Get version numbers when fingerprinting allows
- Copy the full stack as a markdown list for documentation

## Use cases

- Research how competitors build their stack
- Audit a website you're inheriting from another team
- Confirm an A/B testing tool is actually deployed where you expect

## FAQ

### How accurate is Site Stack?

Detection works by scanning network requests, DOM fingerprints, and known global variables. Common stacks (React, Next.js, Vue, Tailwind, Stripe, Segment, GA4) are identified with very high confidence. Obscure or heavily-customized setups may show fewer hits.

### Can sites hide their stack from this?

Yes — sufficiently aggressive obfuscation will hide most fingerprints. DevZap reports what's reasonably detectable; it won't fabricate guesses.

### How is this different from Wappalyzer?

Same general idea, much faster UI, and bundled with the rest of DevZap so you don't need a second extension.

## Details

## Why Site Stack exists

You land on a site, you wonder how they're rendering it, you open DevTools, you scan the Network tab, you check Sources, you guess at the framework based on bundle names. Twenty minutes later you might have an answer.

Site Stack does that whole loop in under a second.

## What it can identify

Frontend frameworks (React, Vue, Svelte, Solid, Astro, Next.js, Nuxt, Remix, SvelteKit), UI libraries (Tailwind, Material UI, Chakra, shadcn/ui), CMS platforms (WordPress, Contentful, Sanity), analytics and experimentation tools (Google Analytics, Plausible, Datafast, PostHog, LaunchDarkly, Optimizely), payment and auth (Stripe, Paddle, Auth0, Clerk, NextAuth), CDN and hosting fingerprints (Vercel, Netlify, Cloudflare), and a long tail of utility libraries that show up in the global scope.

Versions are reported when they're reliably detectable from public bundles.
