Check your dependencies for known vulnerabilities

Upload a lockfile and every dependency is checked against OSV.dev, the open vulnerability database maintained by Google/OpenSSF — free, no signup required.

The package-lock.json file generated by npm install, in your project root.

Nothing is stored. Nothing is logged. Your file is read into memory, parsed into a plain list of package names and versions, checked against OSV.dev's public vulnerability database, and discarded the moment this scan finishes. It is never written to disk, never saved to a database, and never appears in a server log — there is no account and nothing to look back at, even for us.

01

Known CVEs, not just staleness

Every dependency is checked against real, published vulnerability advisories — not just whether a newer version exists.

02

Nothing kept, nothing logged

No account, no database row, no file written to disk. The upload exists only for the seconds it takes to run this scan.
