Built for teams

That act on technology signals

webcop gives GTM, security, product, and engineering teams quick stack intelligence from any URL.

Turn technographics into pipeline

Research prospect stacks before outreach. Know if a lead runs Shopify, WordPress, or a custom Next.js build before your first call.

  • Qualify accounts by CMS and e-commerce platform
  • Personalize outreach with real stack data
  • Spot migration opportunities

7,500+

technology fingerprints

Frameworks, CMS, analytics, CDN, hosting, security, and commerce tools.

AI

for ambiguous matches

Used where ordinary pattern matching needs an extra read on the signals.

<3s

page content stored

The scanner fingerprints public signals without keeping target page content.

Technology lookup

Turn any website into stack intelligence

Paste a URL and get a structured report of frameworks, CMS, CDN, analytics, and version hints where they are detectable.

Useful when you need to

  • Research a prospect or competitor in seconds
  • Avoid digging through DevTools by hand
  • Share a clean report instead of screenshots

API and automation

Put stack checks inside your own workflow

Use the same scanner from the dashboard, REST API, or CLI when you need technology data inside internal tools or scripts.

Useful when you need to

  • API keys managed from your dashboard
  • JSON output for pipelines and enrichment
  • CLI for quick terminal checks

How it works

From URL to tech stack in three steps

No setup, no browser extension required. Paste a link and get a structured technology profile in seconds.

01

Enter a URL

Paste any public website URL — a competitor, a client site, or your own production page.

02

webcop inspects the signals

The scanner checks headers, JavaScript bundles, meta tags, cookies, and DOM patterns in a headless browser.

03

Get a structured stack report

See detected technologies with confidence scores, versions, and categories ready to revisit or share.

Detection

What we inspect on every scan

Each scan loads the target in a headless browser and matches public signals against 7,500+ technology fingerprints.

HTTP response headers

Server software, CDN identifiers, security headers, cache policies, and framework-specific headers like X-Powered-By.

JavaScript and CSS assets

Script URLs, bundle patterns, and library signatures for frameworks, analytics SDKs, chat widgets, and more.

HTML meta and link tags

Generator tags, Open Graph sources, canonical URLs, and stylesheet references that reveal CMS and builder tools.

Cookies and local storage

Session cookies, analytics IDs, and storage keys that map to known platforms and marketing tools.

DOM structure

Class names, data attributes, and embedded iframes that fingerprint page builders, forms, and embeds.

Network and hosting hints

IP ranges, SSL certificate issuers, and DNS patterns that point to hosting providers and CDNs.

Results grouped by category

Scan through a report in seconds instead of sorting through a flat unordered list.

Why webcop

Built for the moment someone asks what they are using

A scanner for quick answers, repeatable research, and automation that needs structured technology data.

AI-assisted resolution

Uses AI where signals are fuzzy, helping separate a real match from a noisy script or shared hosting clue.

7,500+ fingerprints

Frameworks, CMS, CDN, analytics, security tools, hosting, commerce, and more from a broad detection dataset.

Web, CLI, and extension

Scan from the dashboard, terminal, or browser context with one credit balance across every surface.

REST API access

Automate scans in CI/CD, enrich lead records, or add stack detection to internal tools.

Privacy-aware scanning

SSRF protections are built in, and scans fingerprint technology signals instead of storing target page content.

Simple credits

Start with 5 free scans, then pay for what you use with ledger visibility on every debit.

FAQ

Common questions

How is this different from opening DevTools?+

DevTools shows raw page source and network requests — you still have to know what to look for. webcop runs those signals through a maintained fingerprint database and returns structured matches with confidence scores, versions, and categories.

What counts as one credit?+

One credit = one completed scan of one URL. Re-scanning the same URL later uses another credit. Credits never expire, and failed scans caused by our infrastructure are refunded.

Can I scan sites behind a login?+

No. webcop only scans publicly accessible URLs. Private networks, localhost, and internal IPs are blocked at the SSRF validation layer before a scan starts.

Do you store the pages you scan?+

We store the scan result — detected technology names, confidence scores, and metadata like final URL and duration. We don't keep page HTML, screenshots, or visitor data from the target site.

Where does the fingerprint data come from?+

The detection engine uses the Wappalyzer technology dataset — the same open-source fingerprint collection used across the industry, with 7,500+ entries and regular updates.

Is there a free tier?+

Yes. New accounts get 5 credits on sign-up, no credit card required. After that you buy credit packs — see the pricing page for current rates.
