Detect Tech Stack API

What it does

Tech Stack Detector identifies the technologies used by a webpage from its URL. Send an http or https URL in the request body, and get back the source URL plus a technologies array listing the detected stack.

Use it when you need a fast read on what powers a site before a migration, competitive review, security assessment, or integration check. It’s useful for spotting frameworks, libraries, CMS platforms, analytics tools, and other front-end or server-side technologies that leave detectable fingerprints on the page.

The response is intentionally compact: source_url confirms the page that was analysed, and technologies gives you the detected names as strings. That makes it easy to feed the result into enrichment workflows, compare multiple sites, or trigger follow-up checks based on the stack you find.

If you are building a crawler, sales workflow, or site audit pipeline, Tech Stack Detector gives you a simple way to classify web properties from a single URL input without parsing the page yourself.
