Installation

pip install techstackdetect

Quick Start

from techstackdetect import TechStackDetect

client = TechStackDetect(api_key="YOUR_RAPIDAPI_KEY")

result = client.detect("https://stripe.com")

for tech in result.technologies:
    print(f"{tech.name} ({tech.category}) — {tech.confidence:.0%}")
# AWS CloudFront (cdn) — 95%
# Fastly (cdn) — 95%
# HSTS (security) — 90%
# Varnish (cache) — 75%

Usage Examples

Check if a site uses a specific technology

result = client.detect("https://shopify.com")

if result.has("Shopify"):
    print("This site uses Shopify!")

if result.has("React"):
    print("React detected!")

Filter by category

result = client.detect("https://notion.so")

analytics = result.by_category("analytics")
hosting = result.by_category("hosting")
frontend = result.by_category("frontend")

print("Analytics tools:", [t.name for t in analytics])
print("Hosting:", [t.name for t in hosting])

Batch processing for lead enrichment (native /batch endpoint)

leads = [
    "https://woocommerce.com",
    "https://shopify.com",
    "https://ghost.org",
    # ... up to any number of URLs; automatically chunked into 50/request
]

results = client.detect_batch(leads)

for url, result in results:
    if isinstance(result, Exception):
        print(f"{url}: ERROR - {result}")
    else:
        cms = result.by_category("cms")
        ecom = result.by_category("ecommerce")
        print(f"{url}: CMS={[t.name for t in cms]}, ecommerce={[t.name for t in ecom]}")

Browse all supported technologies

# List all ecommerce platforms we can detect
ecom = client.technologies(category="ecommerce")
print(f"Ecommerce platforms: {len(ecom)}")
print([t['name'] for t in ecom[:10]])
# ['BigCommerce', 'Magento', 'OpenCart', 'PrestaShop', 'Shopify', ...]

# List all 5,225 technologies
all_techs = client.technologies()
print(f"Total: {len(all_techs)}")

CRM enrichment workflow

def enrich_lead(website_url):
    result = client.detect(website_url)
    return {
        "url": result.url,
        "cms": next((t.name for t in result.by_category("cms")), None),
        "ecommerce": next((t.name for t in result.by_category("ecommerce")), None),
        "frontend": [t.name for t in result.by_category("frontend")],
        "analytics": [t.name for t in result.by_category("analytics")],
        "hosting": [t.name for t in result.by_category("hosting")],
        "tech_count": len(result.technologies),
    }

print(enrich_lead("https://stripe.com"))

API Reference

TechStackDetect(api_key, timeout=30)

Create a client instance.

client.detect(url, force_refresh=False) → DetectionResult

Detect technologies for a single URL.

client.detect_batch(urls, force_refresh=False, chunk_size=50) → list

Detect technologies for multiple URLs using the native /batch endpoint (parallel server-side processing). Automatically chunks large lists into batches of up to 50 URLs. Returns list of (url, DetectionResult | Exception) tuples.

client.technologies(category=None) → list

List all 5,000+ supported technologies, optionally filtered by category. Available categories: frontend, cms, ecommerce, analytics, cdn, hosting, backend, server, security, marketing, support, payment, ui, monitoring, etc.

Detect technologies for multiple URLs with optional rate limiting.
