I Built a BuiltWith Alternative API at 1/15th the Price

Why I Built This

I needed tech stack detection for a sales intelligence tool. Checked the market:

BuiltWith: $295/mo
Wappalyzer: $250/mo
SimilarTech: $199/mo

For an API call. Seriously?

So I built my own: Tech Stack Detector API — $19/mo unlimited.

How It Works

One API call, instant results:

curl "https://api.lazy-mac.com/tech-stack/api/v1/detect?url=stripe.com"

Returns:

{
  "url": "stripe.com",
  "technologies": {
    "frameworks": ["React", "Next.js"],
    "analytics": ["Google Analytics 4", "Segment"],
    "cdn": ["Cloudflare"],
    "hosting": ["Vercel"],
    "payment": ["Stripe"],
    "cms": [],
    "languages": ["TypeScript", "JavaScript"]
  },
  "detected_count": 8
}

Batch Detection

Need to scan a list of leads? Batch endpoint:

curl -X POST https://api.lazy-mac.com/tech-stack/api/v1/batch \
  -H "Content-Type: application/json" \
  -d '{
    "urls": ["stripe.com", "shopify.com", "vercel.com"]
  }'

Scan your entire prospect list in seconds.

Use Cases

1. Sales Intelligence

"Hey, I noticed you're using React + Vercel — we help React teams ship 2x faster..."

Personalized outreach based on actual tech stack = higher reply rates.

2. Competitive Analysis
Track what technologies your competitors adopt. Spot trends before they become obvious.

3. Lead Enrichment
Plug into your CRM pipeline. Auto-tag leads by their tech stack for better segmentation.

4. Market Research
Scan thousands of sites to understand technology adoption in your industry.

MCP Support

Works with Claude Code, Cursor, and any MCP-compatible tool:

POST https://api.lazy-mac.com/tech-stack/mcp

Your AI coding assistant can look up tech stacks mid-conversation.
