Audit
Field guideStack Scanner
Analyze the technology stack of any website. Our Stack Scanner identifies frameworks, libraries, and server infrastructure for comprehensive technical audits.
What this tool does
A deterministic profiling tool to identify the frameworks, infrastructure, and dependencies powering any web application. Input a URL to generate a complete technology audit.
When to use: Before a migration scoping call, before a security audit, or whenever you need to know what's actually running on a page without installing a browser extension.
Detect a stack
Paste a URL above. We fetch the page through our CORS proxy and pattern-match the HTML against a hand-curated signature database covering CMS, framework, analytics, hosting, libraries, and marketing tools.
