## ProjectDiscovery Nuclei Key Advantages
- 32,087+ GitHub stars under MIT written in Go, executing 10,000+ community-curated YAML vulnerability templates across HTTP, DNS, TCP, SSL, and headless browsers
- Near-zero false positives because every finding is backed by a deterministic, replayable exploit request/response match
- Sub-second CI/CD execution on pull requests and external attack-surface perimeters without heavy Java/browser memory overhead

## OWASP ZAP Key Advantages
- 15,955+ GitHub stars under Apache-2.0 providing a complete stateful web application proxy, passive traffic analyzer, and active parameter fuzzer
- Handles complex multi-step OAuth/OIDC/cookie authentication flows and headless browser AJAX spidering for SPAs (React/Next.js/Vue)
- Turnkey GitHub Actions for Baseline, Full, and OpenAPI/GraphQL/SOAP schema security scans
