I stumbled upon a new open-source tool called BugHunter by shuvonsec. It is an AI-powered bug bounty toolkit built on top of Claude Code that automates the entire vulnerability discovery and reporting pipeline. Already sitting at 3.6k+ stars on GitHub and picking up steam fast.
Official site: github.com/shuvonsec/claude-bug-bounty

What Is BugHunter?
You give it a target, and it handles the whole pipeline from start to finish:
- Recon – subdomain enumeration, tech detection, endpoint discovery
- Hunt – tests 20+ vulnerability classes automatically
- Validate – strict 4-gate validation before reporting
- Report – generates submission-ready reports for HackerOne, Bugcrowd, Intigriti, and Immunefi
What sets it apart is the multi-provider support. You can run it with Claude, Ollama (free), Groq (free tier), or DeepSeek (cheap). No paid subscription required to try it out.
9 Specialized AI Agents
BugHunter ships with 9 AI agents, each handling a specific part of the workflow:
| Agent | Role |
|---|---|
| Recon Agent | Subdomain enumeration, tech detection, endpoint discovery |
| Validator | Verify findings before report submission |
| Report Writer | Generate submission-ready reports |
| Web3 Auditor | Smart contract security audit |
| Chain Builder | Exploit chain analysis |
| Autopilot | Orchestrate the whole pipeline |
| Recon Ranker | Prioritize attack surface |
| Token Auditor | Token and credential security |
| Credential Hunter | Credential leak detection |
All agents come with built-in legal guardrails. The tool hard-stops before any credential spraying or activity without proper authorization.
Vulnerability Coverage
For Web2 (standard web applications), BugHunter covers 20+ vulnerability classes:
- IDOR (Insecure Direct Object Reference)
- SSRF (Server-Side Request Forgery)
- XSS (Cross-Site Scripting)
- SQL Injection
- OAuth misconfiguration
- GraphQL injection
- Race conditions
- LLM injection
- File upload bypass
- JWT attacks
- RCE chainsFor Web3 (smart contracts), there are 10 bug classes including reentrancy, flash loan attacks, oracle manipulation, and proxy/upgrade flaws.
Installation
One command and you are ready to go:
git clone https://github.com/shuvonsec/claude-bug-bounty
cd claude-bug-bounty
./install.sh --agent standalone bughunter setupAfter installation, you pick your AI provider – Ollama (free), Groq (free tier), DeepSeek (cheap), or Claude (full power). If you already use Claude Code, it installs directly as a skill set in ~/.claude/skills/.
Why I Like This Tool
- End-to-end automation – from recon to report in a single pipeline
- Multi-provider – not locked to one AI provider
- Validation gate – strict checks reduce false positives
- Web3 support – rare to see smart contract auditing in a bug bounty tool
- Open source – inspect, modify, and contribute
That said, AI is an assistant, not a replacement. Bugcrowd reports that 82% of hunters now use AI in their workflow, but results still depend on the human directing the AI.
Final Thoughts
If you are tired of repetitive recon or writing reports by hand, BugHunter can save you a lot of time. Especially useful for bug bounty hunters looking to scale their effort without piling on more manual work.
Start with the free providers (Ollama or Groq) before upgrading to Claude. And as always, use it ethically – only against authorized targets.
