π― Why vet?
70-90% of modern software constitute code from open sources β 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:
β
Real-time malicious package detection β Active scanning and analysis of unknown packages
β
Modern SCA with actual usage analysis β Prioritize real risks over vulnerability noise
β
Policy as Code β Express security requirements using CEL expressions
Hosted SaaS version available at SafeDep Cloud.
Get started with GitHub App and other integrations.
β‘ Quick Start
Install in seconds:
# macOS & Linux
brew install safedep/tap/vet
or download a pre-built binary
Get started immediately:
# 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
# Get API key for advanced malware detection

π Key Features
π‘οΈ Malicious Package Detection
Real-time protection against malicious packages powered by SafeDep Cloud.
Free for open source projects. Detects zero-day malware through active code analysis.
π΅οΈ Smart Vulnerability Analysis
Unlike dependency scanners that flood you with noise, vet analyzes your actual code usage to prioritize real risks.
See dependency usage evidence for details.
π Policy as Code
Define security policies using CEL expressions to enforce context specific requirements:
# 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
π― Multi-Ecosystem Support
Package managers: npm, PyPI, Maven, Go, Ruby, Rust, PHP
Container images: Docker, OCI
SBOM formats: CycloneDX, SPDX
Source repositories: GitHub, GitLab
