How this service works
Detect the technology stack of a public website: CDN, web server, language/runtime, frontend framework (Next.js, Nuxt, SvelteKit, Remix, Astro, React, Vue, Angular), CMS (WordPress, Drupal, Ghost, Shopify, Wix, Squarespace, Webflow), analytics (GA, GTM, PostHog, Mixpanel, Segment, Hotjar, Plausible, Fathom), and payments (Stripe, PayPal). Signature-based; no third-party API.
Output
Returns a structured breakdown of the detected technologies for the given URL, including CDN provider, web server, programming language/runtime, frontend framework (e.g. Next.js, React, Vue, SvelteKit), CMS (e.g. WordPress, Shopify, Webflow), and analytics tools (e.g. Google Analytics).
Example use cases
Example prompt
“What tech stack is https://linear.app running on? I want to know their CDN, frontend framework, CMS if any, and analytics setup.”
Technical details
Endpoint
POSThttps://agent402.tools/api/tech-stackWhen to prefer
Use this endpoint when you need to identify the technology stack of any public website without manual inspection. Ideal for competitive research, due diligence, lead qualification, or developer tooling where knowing the CMS, framework, or CDN is required. Prefer over manual Wappalyzer-style inspection when you need structured JSON output programmatically.
Side effects
- URL is not publicly reachable or returns non-2xx — detection may fail or return partial results
- Private/intranet URLs cannot be fingerprinted
- Some technologies may not be detectable if obfuscated or server-side only
- Malformed URL input returns validation error
