Caido

Caido provides a web‑security auditing environment that combines a proxy with AI‑driven testing and collaborative features. It captures HTTP traffic, allowing users to filter requests and responses with an HTTPQL query language, and supports the creation of custom automation workflows through a node‑based interface. The toolkit also offers plugins that can generate payloads, run autonomous agents, and integrate with external large‑language‑model services such as Anthropic, Google, and OpenAI.

The platform is aimed at bug‑bounty hunters, penetration testers, and security engineers who need to accelerate manual testing and embed automation into their workflows. Its API‑first design enables headless operation and programmatic control via a client SDK, while the “bring your own model” option lets teams connect to their preferred LLM provider. Community‑contributed plugins and an active Discord community extend its functionality.

Caido runs on macOS and is positioned as a stable, production‑ready utility that scales manual web assessments through context‑aware AI, instant request filtering, and flexible automation.
