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](https://semgrep.dev) — ~250 additional AST-based rules for JS/TS
• [Gitleaks](https://github.com/gitleaks/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

Use it in CI

GitHub Action

# .github/workflows/security.yml

name: Security on: [push, pull_request] permissions: contents: read security-events: write jobs: scan: runs-on: ubuntu-latest steps:

• uses: actions/checkout@v4
• uses: datahogo/datahogo@main with: fail-on: high

Findings show up in your repository's Security tab automatically. See action.yml for every input (path, url, upload-sarif).

Any other CI

Data Hogo exits with a non-zero code when it finds issues at or above the severity you choose, so it drops straight into any pipeline:

- run: npx datahogo scan --fail-on high --sarif > results.sarif

• uses: github/codeql-action/upload-sarif@v3 if: always() with: sarif_file: results.sarif

The SARIF output shows up in your repository's Security tab.

Commands & options

datahogo [scan] [path]        Scan a directory (default: current directory)

datahogo doctor Check optional external tools

--json Machine-readable JSON output --sarif SARIF 2.1.0 (GitHub Code Scanning) --fail-on Exit 1 if findings >= critical|high|medium|low --url Also scan a deployed URL (headers, SSL, CORS) --explain AI explanations (requires ANTHROPIC_API_KEY) --all Include informational / non-production findings --help, --version

Use it from Claude Code, Cursor, or Claude Desktop (MCP)

@datahogo/mcp exposes the same scan engine as MCP tools, so your agent can scan a project, pull a specific finding, check a deployed URL, or review Supabase/Firebase rules — and write the explanation and fix itself, at no AI cost to you.

claude mcp add datahogo -- npx -y @datahogo/mcp

For Cursor or another MCP client, point it at the same command: npx -y @datahogo/mcp, stdio transport.

Tools: scan_project, get_finding, scan_url, check_db_rules.

Prefer a lighter footprint in Claude Code specifically? Install the Claude Code skill instead — it just teaches the agent to run npx datahogo scan --json and interpret the output, no MCP server process required:

npx skills add datahogo/datahogo/skills/datahogo

Data Hogo Cloud

The CLI is free and always will be. If you want scan history, findings tracked across commits, automatic fix pull requests, scheduled scans, and team dashboards, Data Hogo Cloud builds those on top of the same engine. Using the CLI never requires it.

Contributing

Issues and pull requests are welcome — new detection rules for any language are especially valuable. The scan engine lives in packages/core and the CLI in packages/cli.

git clone https://github.com/datahogo/datahogo.git

cd datahogo npm install npm run build npm test

Support the project

Data Hogo is free and open source. If it saved you from shipping a vulnerability, consider sponsoring the project — it funds new detection rules and keeps the lights on.

Por qué Data Hogo

La mayoría de los escáneres de seguridad te piden acceso a tus repositorios. Data Hogo no. Es una herramienta de línea de comandos que corre completamente en tu máquina: lee tus archivos localmente, encuentra vulnerabilidades y las muestra en tu terminal. No se sube nada. No hay cuenta, no hay registro, no hay servidor en quien confiar. El código está aquí para que lo leas.

Está hecho para developers y vibecoders que lanzan proyectos reales pero no son expertos en seguridad: explica los hallazgos en lenguaje simple y, si quieres, genera arreglos usando tu propia llave de AI.

npx datahogo

Eso es todo. Apúntalo a un proyecto y escanea el directorio actual.

Inicio rápido

# Escanear el directorio actual

npx datahogo

Escanear una ruta específica

npx datahogo scan ./mi-app

Romper el CI si hay hallazgos de severidad alta

npx datahogo scan --fail-on high

Generar SARIF para GitHub Code Scanning

npx datahogo scan --sarif > results.sarif

Instálalo de forma global si prefieres no usar npx cada vez:

npm install -g datahogo

datahogo scan

Qué revisa

Data Hogo detecta tu stack automáticamente y corre los analizadores que correspondan. La cobertura es más profunda en el ecosistema JavaScript/TypeScript; los demás lenguajes tienen un conjunto enfocado de checks de alta señal.

La detección de secretos y el escaneo de dependencias corren en todos los proyectos sin importar el lenguaje.

Opcional: análisis más profundo

Dos herramientas estándar de la industria agregan profundidad extra si las tienes instaladas. Data Hogo funciona bien sin ellas: usa sus checks integrados y te dice qué te estás perdiendo.

datahogo doctor   # muestra qué tienes instalado y cómo agregar lo demás

• [Semgrep](https://semgrep.dev) — ~250 reglas adicionales basadas en AST para JS/TS
• [Gitleaks](https://github.com/gitleaks/gitleaks) — conjunto completo de reglas de detección de secretos

Explicaciones y arreglos con AI (usa tu propia llave)

Cada hallazgo viene con una explicación en lenguaje simple y un arreglo sugerido de fábrica. Si quieres arreglos más ricos y con contexto generados por Claude, configura tu propia llave de API de Anthropic: las llamadas van directo de tu máquina a Anthropic, facturadas a ti. Nosotros nunca las vemos.
