But it is also worth noting that OWASP Zap has more false positives than Burp Suite Pro.

Moreover, Burp Suite Pro includes more coverage than OWASP Zap. In addition, OWASP Zap provides little documentation, which may be why some people prefer Burp Suite Pro (which offers extensive documentation). OWASP Zap is maintained by volunteers whereas Burp Suite Pro is a commercial product maintained and sold by PortSwigger, which makes me feel more confident in it. OWASP Zap is free, but Burp Suite Pro requires a paid subscription (currently $399 per year). One big difference between the two, though, is price. Both OWASP Zap and PortSwigger Burp Suite Pro have a spider feature, and provide updates. Both are very comparable in terms of intercepting features, fuzzing capabilities, and encoder and decoders. OWASP Zap has web application scanning available with basic security vulnerabilities while Burp Suite Pro has it available with quality security vulnerabilities. OWASP Zap and PortSwigger Burp Suite Pro have many similar features.
