70-90% of modern software constitute code from open sources — How do we know if it's safe?

vet is an open source software supply chain security tool built for developers and security engineers who need:

✅ Next-gen Software Composition Analysis — Vulnerability and malicious package detection
✅ Policy as Code — Express opinionated security policies using CEL
✅ Real-time malicious package detection — Powered by SafeDep Cloud active scanning
✅ Multi-ecosystem support — npm, PyPI, Maven, Go, Docker, GitHub Actions, and more
✅ CI/CD native — Built for DevSecOps workflows with support for GitHub Actions, GitLab CI, and more
✅ MCP Server — Run vet as a MCP server to vet open source packages from AI suggested code

Install in seconds:

# macOS & Linux
brew install safedep/tap/vet

or download a pre-built binary

Scan your project:

# Scan current directory
vet scan -D .

# Scan a single file
vet scan -M package-lock.json

# Fail CI on critical vulnerabilities
vet scan -D . --filter 'vulns.critical.exists(p, true)' --filter-fail

# Fail CI on OpenSSF Scorecard requirements
vet scan -D . --filter 'scorecard.scores.Maintained < 5' --filter-fail

# Fail CI if a package is published from a GitHub repository with less than 5 stars
vet scan -D . --filter 'projects.exists(p, p.type == "GITHUB" && p.stars < 5)' --filter-fail

Unlike dependency scanners that flood you with noise, vet analyzes your actual code usage to prioritize real risks. See dependency usage evidence for more details.

Integrated with SafeDep Cloud for real-time protection against malicious packages in the wild. Free for open source projects. Fallback to Query Mode when API key is not provided. Read more about malicious package scanning.

Define security policies using CEL expressions to enforce context specific security requirements.

# Block packages with critical CVEs
vet scan \
--filter 'vulns.critical.exists(p, true)'

# Enforce license compliance
vet scan \
--filter 'licenses.contains_license("GPL-3.0")'

# Enforce OpenSSF Scorecard requirements
# Require minimum OpenSSF Scorecard scores
vet scan \
--filter 'scorecard.scores.Maintained < 5'

Malicious package detection through active scanning and code analysis powered by SafeDep Cloud. vet requires an API key for active scanning of unknown packages. When API key is not provided, vet will fallback to Query Mode which detects known malicious packages from SafeDep and OSV databases.

• Grab a free API key from SafeDep Platform App or use vet cloud quickstart
• API access is free forever for open source projects
• No proprietary code is collected for malicious package detection
• Only open source package scanning from public repositories is supported

Malicious package detection requires an API key for SafeDep Cloud.

# One-time setup
vet cloud quickstart

# Enable malware scanning
vet scan -D . --malware

# Query for known malicious packages without API key
vet scan -D . --malware-query

Example malicious packages detected and reported by SafeDep Cloud malicious package detection:

• MAL-2025-3541: express-cookie-parser
• MAL-2025-4339: eslint-config-airbnb-compat
• MAL-2025-4029: ts-runtime-compat-check
• MAL-2025-2227: nyc-config

# Real-time scanning
vet scan -D . --malware

# Timeout adjustment
vet scan -D . --malware \
  --malware-analysis-timeout=300s

# Batch analysis
vet scan -D . --malware \
  --json-dump-dir=./analysis

# VS Code extensions
vet scan --vsx --malware

# GitHub Actions
vet scan -D .github/workflows --malware

# Container Images
vet scan --image nats:2.10 --malware

# Scan a single package and fail if its malicious
vet scan --purl pkg:/npm/[email protected] --fail-fast

# Active scanning of a single package (requires API key)
vet inspect malware \
  --purl pkg:npm/[email protected]

• ✅ Real-time analysis of packages against known malware databases
• ✅ Behavioral analysis using static and dynamic analysis
• ✅ Zero day protection through active code scanning
• ✅ Human in the loop for triaging and investigation of high impact findings
• ✅ Real time analysis with public analysis log

vet collects anonymous usage telemetry to improve the product. Your code and package information is never transmitted.
