An autonomous AI pentester for web apps and APIs that proves every finding, on your ChatGPT Plus or Pro plan.

About Shannon
Shannon analyses your source code, identifies attack paths and executes real exploits against your web application or API to prove a vulnerability before it reaches production: no exploit, no report. Shannon Open Source runs the full agent locally from your command line, and its latest version supports ChatGPT Plus and Pro subscriptions through the OpenAI Codex provider.
