How this service works
Tech stack detection: what a website is built with (CMS, frameworks, e-commerce, analytics, ads, chat, payments, CDN, hosting, server) with the evidence for each.
Output
A structured breakdown of the technologies detected on the target website, organized by category (CMS, frameworks, e-commerce, analytics, ads, chat, payments, CDN, hosting, server), each accompanied by evidence such as HTTP headers, script patterns, or HTML signatures that confirm the detection.
Example use cases
Competitor technology stack audit
“Can you figure out what technology stack shopify.com is using? I want to know their CMS, front-end frameworks, analytics tools, and CDN provider.”
E-commerce platform identification
“What e-commerce platform is allbirds.com built on? And does it use any third-party payment or chat integrations?”
Sales lead tech qualification
“Before I reach out to this prospect, can you check what tools notion.so is running — specifically their marketing analytics, ad networks, and CRM or chat software?”

Endpoint
GEThttps://agents.citiviewgroup.com/v1/techstack?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, categorized technology fingerprinting of a website with evidence, especially when you need coverage across multiple tech categories (CMS, CDN, payments, analytics) in a single call. Prefer it over generic web scraping when the goal is technology identification rather than content extraction, and over manual inspection when you need fast, automated results at low cost ($0.005/call).
Side effects
- Invalid or unreachable URL returns an error or empty result
- Private or localhost domains cannot be inspected
- Some technologies may be obfuscated or minified and go undetected
- Rate limiting or bot-blocking on the target site may prevent evidence collection
- Very new or highly custom stacks may yield no recognized technology matches
