The detector identifies 150+ technologies across 15+ categories: frontend frameworks (React, Vue, Angular, jQuery), backend platforms (Node.js, Django, Rails, PHP), CMS (WordPress, Shopify, Squarespace), CDNs (Cloudflare, Fastly, Akamai), analytics (Google Analytics, Plausible, Hotjar), e-commerce (Shopify, WooCommerce), monitoring (Sentry, Datadog), marketing (HubSpot, Mailchimp), chat widgets, fonts, security tools, and hosting platforms.
The tool analyzes HTTP response headers, HTML meta tags, script sources, CSS references, and known URL patterns. Each detection includes a confidence level (high, medium, or low) based on how definitive the signal is.
Yes. You can analyze any public website to understand what technologies your competitors use — their frontend framework, analytics tools, CDN provider, CMS platform, and more. The JSON API makes it easy to scan multiple sites programmatically.
Integrate tech stack detection into your scripts, monitoring, or sales tools:
curl "https://51-68-119-197.sslip.io/api/techstack?url=https://example.com"
import urllib.request, json
url = "https://51-68-119-197.sslip.io/api/techstack?url=https://example.com"
data = json.loads(urllib.request.urlopen(url).read())
for tech in data['technologies']:
print(f"{tech['name']} ({tech['category']}) — {tech['confidence']}")
const resp = await fetch('https://51-68-119-197.sslip.io/api/techstack?url=https://example.com');
const data = await resp.json();
console.log(`${data.technologies_detected} technologies found`);
data.technologies.forEach(t => console.log(`${t.name} (${t.category})`));
resp, _ := http.Get("https://51-68-119-197.sslip.io/api/techstack?url=https://example.com")
defer resp.Body.Close()
body, _ := io.ReadAll(resp.Body)
fmt.Println(string(body))
