Website Tech Stack Detector

Feed it a domain. Get back the entire tech DNA: CMS, frontend frameworks, backend infrastructure, analytics, CDN, and 60+ technologies in their stack.

Ever wonder what tech your competitor is using? Or what stack successful companies in your space are built on? This actor crawls a domain and identifies every major technology: their CMS (WordPress, custom Node.js), frontend framework (React, Vue), backend language, hosting provider, analytics tools, payment processors, email services, and more.

🎯 Use Cases

• Sales Intelligence: What's their tech stack? If they're using your competitor's product, you know what to pitch. If they're using outdated tech, that's an opening.
• Product Teams: Benchmark against competitors. Which frameworks do successful companies use? Are you using the same infrastructure?
• Investors: Due diligence. A founder using outdated tech or expensive servers signals poor judgment. Modern stack signals technical competence.
• Talent Acquisition: Want to hire engineers? See which companies use the stack you value. Can you attract their engineers with the same tech?
• M&A Research: Evaluate acquisition targets. Assess tech debt, infrastructure choices, and integration complexity before due diligence.
• Integration Partnerships: Which tools do your target customers use? Build integrations with their entire stack.

🔌 Works Great With

• Crunchbase Company Scraper — Get funding data, then scan their tech stack. Newly-funded? Check if they're scaling infrastructure.
• Competitive Intelligence Engine — Combine tech stack with feature analysis. What are they building?
• Product Review Aggregator — See how customers rate competitors' products, then understand their tech choices.
• GitHub MCP Wrapper — Find their open-source repos. Dive deeper into their actual codebase.

💰 Cost & Performance

Typical run: 100 domains fully profiled in 2 minutes for ~$2.40.

That's $0.024 per domain — cheaper than a phone call with a prospect.

Compare to manual: One developer manually researching a tech stack takes 30 minutes. At $50/hour, that's $25 per company. We do 100 for $2.40.

🛡️ Built Right

• JavaScript rendering captures dynamically-loaded tech
• Header analysis detects servers, CDNs, security tools
• Script scanning identifies analytics, marketing, payment processors
• Performance metrics included with every scan
• Version detection where possible (React 18.2 vs 17.x matters)
• Confidence scoring tells you which detections are certain vs inferred
