Know your deployed versions?

Optional. Server versions are usually hidden. Enter exact versions from your deployment; they will be marked as provided by you.

Up to 30 public npm or Python packages, one exact version per line. Python: pip==26.2.1. npm: npm:next@16.4.0. Copy from the deployed environment, not your laptop.

Only these package names and versions are sent to OSV for comparison. Do not paste private packages, credentials, URLs or install commands. No packages are installed or executed.

We check the page’s security settings and read up to 8 linked JavaScript files from the same origin to identify library versions. Scripts are never executed. Hidden server versions remain unverified.

Security news from trusted sources

These are ecosystem alerts, not findings about your website. A package and version match is required before attributing an alert to your project.
