Caido

Caido enables the interception, inspection, and modification of HTTP requests directly within the browser environment. It allows researchers to alter request headers, payloads, and parameters while preserving active session cookies and authentication tokens, ensuring continuous access to protected application endpoints during security assessments.

Caido is designed for penetration testers, security researchers, and web application developers who require granular control over network traffic. It is specifically built for professionals conducting manual security audits, vulnerability research, and bug bounty hunting who need to manipulate requests without disrupting their authenticated session state.

Users require a functional web browser and the Caido environment configured to proxy traffic. It relies on the underlying application's authentication mechanisms, meaning valid session cookies or bearer tokens must be present in the browser environment for the interception and modification features to function effectively.
