Best for: Teams wanting managed DAST without self-hosting
OWASP ZAP is one of the highest-ROI free tools in security — application security engineers, QA testers, DevSecOps teams, and bug-bounty hunters get a fully open-source DAST scanner that competes with $499/year Burp Suite Professional and $25,000+/year Veracode DAST. Teams of any size benefit because the cost is zero; the only investment is a few hours learning the API and CI/CD integration patterns. There is no upgrade path because ZAP itself is free, but teams wanting a managed SaaS DAST experience without self-hosting should evaluate StackHawk (built on ZAP) starting at $79/month. Compared to commercial DAST scanners, ZAP saves $25,000–$100,000+/year per team while providing comparable OWASP Top 10 coverage and superior CI/CD friendliness.
OWASP ZAP itself is free under the Apache 2.0 license — no discounts apply because there are no costs. The OWASP Foundation accepts donations to support ZAP development but provides no paid tier. StackHawk (commercial managed SaaS built on ZAP) offers a free tier and student/non-profit discounts; check their pricing page for current rates. There is no trial because ZAP is permanently free — download from zaproxy.org.
Yes, OWASP ZAP is completely free and open-source under the Apache 2.0 license. The full DAST scanner including active and passive scanning, fuzzer, and CI/CD Docker images is free for everyone.
