CST VerdictBased on our analysis of available product data, here is our conclusion:
Security teams mapping external attack surface for web applications should start with Wappalyzer because it identifies technology stacks faster and cheaper than manual reconnaissance, and the free tier actually works without constant upsells. You get API access to scan hundreds of sites monthly, which beats the pay-per-lookup model competitors use. Skip this if you need continuous passive monitoring of your own infrastructure or vulnerability correlation baked in; Wappalyzer is a lookup tool, not a persistent scanner, so you're running point-in-time checks rather than feeding live asset data into your SIEM.
Security teams conducting external attack surface discovery on a budget will get the most from ZoomEye; its free tier gives you real-time visibility into exposed assets and service versions across your internet-facing infrastructure without licensing friction. The search engine indexes over 600 million IP addresses and devices, letting you identify vulnerabilities before an attacker does. Skip this if you need continuous posture monitoring or remediation workflows; ZoomEye is a reconnaissance tool, not a management platform.
