Hacktoberfest is here again, and Repello AI is thrilled to invite developers, security researchers, and AI enthusiasts to contribute to our open-source projects! This is a fantastic opportunity to dive into the world of AI security, enhance your skills, and potentially land full-time opportunities or internships with our team.

At Repello AI, we are dedicated to building robust AI security solutions. We believe in the power of community and open source to drive innovation and create a safer AI ecosystem. This Hacktoberfest, we're spotlighting two of our exciting projects:

Our Projects:

1. Agent-Wiz: Static Threat Analysis for AI Agents

Agent-Wiz is a CLI tool for threat modeling and visualizing AI agents built using popular frameworks like LangGraph, AutoGen, CrewAI, and more.

2. Whistleblower: Offensive Security for AI Applications

Whistleblower is an offensive security tool specifically built for testing against system prompt leakage and capability discovery of AI applications exposed through APIs. It’s an essential tool for AI engineers, security researchers, and anyone curious about the inner workings and potential vulnerabilities of the LLM-based apps they use daily.
