Caido CLI

Caido CLI is a lightweight web security auditing toolkit available as a command-line interface. It provides options for configuring listeners, proxies, and UI for security testing.

Description

Caido CLI is part of the Caido security auditing toolkit, specifically the CLI component packaged for Kali Linux. This tool enables users to perform web security audits through a command-line interface, supporting features like listening addresses, proxy configurations, and UI access controls.

Use cases include setting up local proxies for traffic interception, running invisible mode listeners for stealthy operations, and managing UI domains for controlled access during audits. It is designed for security professionals needing a lightweight alternative to full GUI-based tools.

The package integrates seamlessly into Kali Linux environments, with dependencies on standard libraries like libc6 and libgcc-s1, making it suitable for penetration testing workflows.

How It Works

Caido CLI operates by binding to specified network addresses and ports for listening on proxies and UI services. It supports invisible mode to hide listeners, sync options with servers, and debug logging for troubleshooting. The tool handles web traffic routing through proxy listeners and serves a UI on designated ports with domain restrictions, facilitating interactive security audits via command-line control.
