Our verdict on Vendetect
Vendetect is an open-source command-line tool from Trail of Bits for detecting copied and vendored code between Git repositories. It is designed for developers, security researchers, and organizations investigating code provenance. The tool compares local or remote repositories, identifies similar files and matched code sections, displays similarity scores, and can analyze selected repository subdirectories. Its self-hosted model suits teams that want repository analysis within their own environments rather than a hosted service.
Its standout capability is semantic comparison. Vendetect uses semantic fingerprinting to identify related code even when variable names or comments differ, giving it a broader detection approach than simple text matching. Users can filter analysis by file type and inspect Git repository history, which supports investigations that need more than a current-state comparison. Results are available in rich, CSV, and JSON formats, making the output suitable for interactive review or structured downstream handling.
Vendetect is a strong fit when the core requirement is comparing repositories and tracing potentially copied or vendored code through a focused CLI. The self-hosted, open-source model also gives organizations a way to run the tool within their own infrastructure. Teams seeking a broader developer platform, built-in CI workflows, or an extensive integration layer should consider alternatives with those capabilities. Choose Vendetect for semantic repository analysis; look elsewhere when clone detection is only one part of a wider code-management workflow.
