> [!NOTE]
> `vet` also runs in the cloud. Point it at your GitHub repositories and get continuous scanning, malware detection, and policy enforcement without managing any infrastructure. See [SafeDep Cloud](https://safedep.io/) for the end-to-end software supply chain security platform.
## Why vet?
> **70-90% of modern software is open source code** — how do you know it's safe?
Traditional SCA tools drown you in CVE noise. **vet** takes a different approach:
- **Shadow AI discovery** — Discover AI tool usage signals across various tools and configurations
- **Catch malware before it ships** — Zero-day detection through static and dynamic behavioral analysis (requires SafeDep Cloud access)
- **Cut through vulnerability noise** — Analyzes actual code usage to surface only the risks that matter
- **Enforce policy as code** — Express security, license, and quality requirements as [CEL](https://cel.dev/) expressions
- **CI/CD integration** — Zero-config security guardrails in CI/CD
Free for open source. Hosted SaaS available at [SafeDep](https://safedep.io).
## Quick Start
**Install in seconds:**
```bash
# macOS & Linux
brew install vet
# Using npm
npm install -g @safedep/vet
```
or download a [pre-built binary](https://github.com/safedep/vet/releases)
**Get started immediately:**
```bash
# Scan for malware in your dependencies
vet scan -D . --malware-query
# Fail CI on critical vulnerabilities
vet scan -D . --filter 'vulns.critical.exists(p, true)' --filter-fail
```
## Architecture
`vet` follows a pipeline architecture: **readers** ingest package manifests from diverse sources (directories, repositories, container images, SBOMs), **enrichers** augment each package with vulnerability, malware, and scorecard data from SafeDep Cloud, the **CEL policy engine** evaluates security policies against enriched data, and **reporters** produce actionable output in formats like SARIF, JSON, and Markdown.

## Key Features
### **Malicious Package Detection**
Real-time protection against malicious packages powered by [SafeDep Cloud](https://docs.safedep.io/cloud/malware-analysis).
Free for open source projects. Detects zero-day malware through active code analysis.
### **Vulnerability Analysis**
Unlike dependency scanners that flood you with noise, `vet` analyzes your **actual code usage** to prioritize real risks.
See [dependency usage evidence](https://docs.safedep.io/vet/guides/dependency-usage-identification) for details.
### **Policy as Code**
Define security policies using CEL expressions to enforce context specific requirements:
```bash
# Block packages with critical CVEs
vet scan --filter 'vulns.critical.exists(p, true)' --filter-fail
# Enforce license compliance
vet scan --filter 'licenses.contains_license("GPL-3.0")' --filter-fail
# Require minimum OpenSSF Scorecard scores
vet scan --filter 'scorecard.scores.Maintained < 5' --filter-fail
```
### **Multi-Ecosystem Support**
Package managers: **npm**, **PyPI**, **Maven**, **Go**, **Ruby**, **Rust**, **PHP**
Container images: **Docker**, **OCI**
SBOM formats: **CycloneDX**, **SPDX**
Source repositories: **GitHub**, **GitLab**
## Malicious Package Detection
**Real-time protection against malicious packages** by querying SafeDep's threat intelligence
database, continuously populated through static and dynamic behavioral analysis.
### Quick Setup
```bash
# Query known malicious packages (no API key needed)
vet scan -D . --malware-query
```
> [!NOTE]
> The `--malware` flag is deprecated. Active (on-demand) scanning has been retired in favour of
> querying SafeDep's threat intelligence database. `--malware` now behaves identically to
> `--malware-query` and is retained for backward compatibility.
**Example detections:**
- [MAL-2025-3541: express-cookie-parser](https://safedep.io/malicious-npm-package-express-cookie-parser/)
- [MAL-2025-4339: eslint-config-airbnb-compat](https://safedep.io/digging-into-dynamic-malware-analysis-signals/)
- [MAL-2025-4029: ts-runtime-compat-check](https://safedep.io/digging-into-dynamic-malware-analysis-signals/)
**Key security features:**
- Real-time lookups against SafeDep's known malicious packages database
- Behavioral analysis using static and dynamic analysis (performed continuously in SafeDep Cloud)
- Human-in-the-loop triaging for high-impact findings
- Public [analysis log](https://vetpkg.dev/mal) for transparency
### Advanced Usage
```bash
# Specialized scans
vet scan --vsx --malware-query # VS Code extensions
vet scan -D .github/workflows --malware-query # GitHub Actions
vet scan --image nats:2.10 --malware-query # Container images
```
> [!NOTE]
> The `vet inspect malware` command (on-demand analysis of a single package) is deprecated and
> will be removed in a future release. Use `vet scan --malware-query` to check packages against
> SafeDep's known malicious packages database.
