Burp Suite Professional (AI Edition)

The world's #1 web penetration testing toolkit. The 2026 edition features 'Burp AI' for autonomous vulnerability exploitation, a React-native UI modernization, and native support for OpenAPI 3.1. While its manual testing depth is peerless, its high Java resource consumption, rising price, and 'credit-based' AI usage can be restrictive for individual researchers.
