7 alternatives to shannon

keygraphhq/shannon — Shannon is an AI pentester for web applications and APIs. It analyzes your source code, identifies attack vectors, and executes real exploits to prove vulnerabilities before they reach production. (49,333 stars, AGPL-3.0, auth, ai, infra).

These are the closest projects in the JustClaw-It index that we serve licence-cleared code from, ranked by relevance and by our code-quality score (1–10, the mean over each repo's graded components: completeness, code quality, deployability, reusability, strategic value). JustClaw-It does not serve code from keygraphhq/shannon itself (licence class: network-copyleft), so these alternatives are the licence-cleared route.
