Technology Detector
Competitive IntelligenceTestedWebsite technology identification — CMS, analytics, ad pixels, frameworks, CDNs, and 3,000+ signatures.
Technology Detector scans any website and identifies the technologies powering it — CMS platforms, analytics tools, advertising pixels, JavaScript frameworks, CDNs, ecommerce platforms, marketing automation, and more. It uses over 3,000 open-source signatures from the webappanalyzer project (successor to Wappalyzer) to match against HTTP headers, HTML content, script URLs, and meta tags.
Ask what tech stack a competitor is using, which analytics tools are installed on a site, or what CMS a domain runs on. Agentcy fetches the page and matches against the full signature database, returning categorized results with confidence levels.
This is an always-available bundled service — no setup required. Scans any public URL.

Start asking about any website's technology stack
24-hour cache. Technology stacks change infrequently — results reflect the site state at scan time.
Detection is based on server-side signals (headers, HTML, scripts) — technologies that leave no public footprint may not be detected
Some sites actively strip technology fingerprints from their responses for security
Version detection is approximate — exact version numbers are only available when the technology exposes them in headers or scripts
Single-page scan — the technology stack on internal pages may differ from the homepage
