How this service works
Detect the technologies a website uses (CMS, frameworks, analytics, CDN). Detects CMS, e-commerce platform, JS framework, analytics, payments, CDN and server software from a page's HTML and headers.
Output
A JSON object listing the detected server software (e.g. 'cloudflare') and an array of identified technologies (e.g. ['Shopify', 'Google Tag Manager', 'Cloudflare']), based on analysis of the target page's HTTP headers, HTML, and scripts.
Example use cases
Competitor tech stack research
“Can you figure out what tech stack my competitor acme.com is using? I want to know their server, CDN, CMS, and any frontend frameworks.”
Sales prospecting qualification
“Before I pitch them on our DevOps solution, can you check what technologies hubspot.com is running so I know if they'd be a good fit?”
Security audit pre-check
“I'm starting a security assessment of example.com — can you pull their full technology fingerprint so I know what software I'm dealing with?”
Technical details
Endpoint
GEThttps://sift.srv1996466.hstgr.cloud/v1/tech?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call technology fingerprint of any public website without setting up your own crawling infrastructure. It is ideal for competitive intelligence, sales qualification, security scoping, or partner due diligence. Prefer it over manual inspection or dedicated OSINT platforms when cost-per-call economics matter and you need JSON output compatible with automated pipelines.
Side effects
- Non-public or paywalled URLs may return incomplete or empty technology lists
- Heavily obfuscated or headless-only sites may evade detection
- Invalid or unreachable URLs return an error rather than HTTP 200 (no charge)
- Some modern SPAs may not expose enough signals for full detection
- Rate limits or bot-blocking on the target site may prevent successful fetching
