Why Data Hogo

Most security scanners ask you to hand over access to your repositories. Data Hogo doesn't. It's a CLI that runs entirely on your machine — it reads your files locally, finds vulnerabilities, and prints them to your terminal. Nothing is uploaded. There's no account, no sign-up, and no server to trust. The source is here for you to read.

It's built for developers and vibecoders who ship real projects but aren't security experts: it explains findings in plain language and, if you want, generates fixes using your own AI key.

npx datahogo

That's it. Point it at a project and it scans the current directory.

Quick start

# Scan the current directory
npx datahogo

# Scan a specific path
npx datahogo scan ./my-app

# Fail CI if there are high-severity findings
npx datahogo scan --fail-on high

# Output SARIF for GitHub Code Scanning
npx datahogo scan --sarif > results.sarif

Install it globally if you'd rather not use npx every time:

npm install -g datahogo
datahogo scan

What it checks

Data Hogo auto-detects your stack and runs the matching analyzers. Coverage is deepest for the JavaScript/TypeScript ecosystem; other languages have a focused set of high-signal checks.

Secrets detection and dependency scanning run across every project regardless of language.

Optional: deeper analysis

Two industry-standard tools add extra depth when installed. Data Hogo works fine without them — it just uses its built-in checks and tells you what you're missing.

datahogo doctor   # shows what's installed and how to add the rest

• Semgrep — ~250 additional AST-based rules for JS/TS
• Gitleaks — comprehensive secret-detection ruleset

AI explanations & fixes (bring your own key)

Every finding comes with a plain-language explanation and a suggested fix out of the box. If you want richer, context-aware fixes generated by Claude, set your own Anthropic API key — the calls go directly from your machine to Anthropic, billed to you. We never see them.

export ANTHROPIC_API_KEY=sk-ant-...
datahogo scan --explain
