At a glance

Three tools, three different jobs

BuiltWith
Enterprise lead generation and sales prospecting
Free tier limited · Paid from ~$295/mo

BuiltWith has the largest technology database and the best tools for bulk prospecting — CRM integrations, domain lists, historical data. But it is expensive, and its free tier is heavily restricted. Everything you actually need for analysis requires a paid plan.

Strengths
Largest technology fingerprint database
Historical technology usage data
Bulk domain list scanning
CRM integrations (Salesforce, HubSpot)
Browser extension available
Limitations
No Stack Health Score or qualitative analysis
No AI insights — raw data only
Free tier severely limited
Expensive for individuals and small teams
Interface can feel data-heavy without context
Wappalyzer
Browser-based lookups while actively browsing
Free tier limited · Paid from ~$149/mo

Wappalyzer's browser extension is genuinely convenient for quick checks while browsing. The free tier is usable for casual lookups. But for any serious analysis — comparison, export, API — you hit a paywall. And it has no scoring or AI layer at all.

Strengths
Convenient browser extension
Real-time detection while browsing
Clean minimal interface
API available for developers
Good for casual free lookups
Limitations
No Stack Health Score or health assessment
No AI insights or risk analysis
Side-by-side comparison requires paid plan
Export behind paywall
Misses many server-side technologies
TrueTechFinder

Completely free · No account required
