Frequently Asked Questions

How accurate is the detection?

We use multiple detection methods for each technology:

• HTML pattern matching - Script tags, CSS classes, meta tags
• Header analysis - Server, CDN, and X-Powered-By headers
• Domain fingerprinting - Known CDN and platform domains

Our confidence scoring (HIGH/MEDIUM/LOW) helps you understand detection reliability.

What's the difference between this and BuiltWith?

BuiltWith costs $295+/month and detects thousands of obscure technologies you'll never need. We focus on the 100+ technologies that actually matter for business decisions, at $0.02 per site. Plus, we extract contacts and support industry-specific platforms.

Can it detect ServiceTitan, Mindbody, or Toast?

Yes! We're one of the few tech detection tools that identifies industry-specific business software:

• Home services: ServiceTitan, Housecall Pro, Jobber
• Fitness: Mindbody, Vagaro, Zenoti
• Restaurants: Toast, Square, Clover
• Healthcare: Jane App, SimplePractice
• And 50+ more

Why can't it access some websites?

Some websites use aggressive bot protection. Try these options:

1. Enable Firecrawl fallback - Works on most protected sites
2. Enable Camoufox anti-detection - Browser fingerprint masking
3. Use residential proxies - Apify automatically uses them

How do I integrate with Make.com or Zapier?

Use the webhookUrl parameter to receive results via POST request when the actor completes. The output includes techStackString and contactsString fields for easy parsing.

Can I analyze thousands of websites?

Yes! The actor handles large batches efficiently. For best results:

• Keep deepScan off for faster processing
• Use the default concurrency settings
• Consider breaking very large jobs into batches of 500-1000

What's Demo Mode?

Demo mode returns sample data without actually scraping websites. It's completely free and lets you preview the output format before running live analysis.

How do I get a Firecrawl API key?

Visit firecrawl.dev to sign up and get your API key. Firecrawl provides excellent access to protected websites that standard scraping can't reach.

Common Problems & Solutions

"Site blocked" or empty results

Cause: The website has bot protection. Fix: Enable useFirecrawl: true and provide your Firecrawl API key, or enable useCamoufox: true.

Fewer technologies detected than expected

Cause: Technologies may be loaded dynamically or on inner pages. Fix: Enable deepScan: true to scan multiple pages per site.

Demo data showing instead of real results

Cause: demoMode is set to true. Fix: Set demoMode: false in your input.

Contact extraction missing data

Cause: Some websites don't display contact information on their homepage. Fix: Enable deepScan: true to check contact/about pages.

Timeout errors on large batches

Cause: Too many concurrent requests. Fix: Reduce batch size or run in smaller groups of 100-200 sites.
