Every cloud audit fingerprints the technologies a site is built with - **385 signatures** across CMS, frameworks, CDN & hosting, analytics, tag managers, payment processors, chat widgets, fonts, and security/consent tools - and surfaces them as a dedicated **Technologies** section in the report.

It's informational: technology detection **never affects your health score**. It's there to give you - and your agent - context about what you're auditing.

## What it detects

Detection runs against response headers, HTML, inline and external scripts, cookies, and meta tags, and reports versions where they can be determined. Results are grouped by category:

| Category | Examples |
|----------|----------|
| CMS & Ecommerce | WordPress, Shopify, Webflow, Ghost |
| Frameworks & Libraries | Next.js, Astro, React, Vue, Svelte |
| Web Servers | nginx, Apache, Caddy |
| Hosting | Vercel, Netlify, AWS, GitHub Pages |
| CDN & Edge | Cloudflare, Fastly, Akamai |
| Analytics | Google Analytics, Plausible, Cloudflare Web Analytics |
| Tag Managers | Google Tag Manager |
| Advertising | Google AdSense, ad networks |
| Payments | Stripe, PayPal, Shopify Payments |
| Support & Chat | Intercom, Crisp, Zendesk |
| Security & Consent | OneTrust, reCAPTCHA, hCaptcha |
| Fonts, Video & Media, Widgets & UI | Google Fonts, YouTube, OneTrust |

A typical result:

```
TECHNOLOGIES
Detected tech stack - informational, not part of the score. No changes since last scan.
🧩 Frameworks & Libraries   Astro 6.3.7
🌐 CDN & Edge               Cloudflare
📊 Analytics                Cloudflare Web Analytics
🏷️ Tag Managers             Google Tag Manager
🔒 Security & Consent       OneTrust
```

Technologies appear in **every output format** - console, HTML, Markdown, JSON, XML, and LLM - with logos in the visual formats.

## When it runs

- **Logged in** - detection runs automatically as part of every cloud audit. One detection per domain, regardless of how many pages you crawl.
- **Logged out or `--offline`** - skipped, like every other cloud feature. Your local rules still complete.

Detection is best-effort and never fails the audit: if the service is unavailable, the Technologies section is simply omitted and you're not charged.

## Cost

**5 credits per audit** - a single detection per domain, not per page. See [Credits & Pricing](/cloud/credits).

## Change history

squirrelscan keeps a per-domain record of what it has detected over time, so you can see when a site adopts or drops a technology - a CMS migration, a new analytics vendor, a CDN switch.

- **Current snapshot** - free, shown on every audit. The report notes whether anything changed since the last scan ("No changes since last scan").
- **Historical timeline** - the full add / remove history for a domain is a **paid-plan** feature, available in the [dashboard](/dashboard).

<Note>Technology data is keyed by domain and shared: the current detected stack for a domain is the same for everyone who audits it, so the snapshot stays fast and consistent across re-audits.</Note>
