What is OSS Scanner?

OSS Scanner is an Anthropic service for eligible open-source projects that provides free, periodic AI vulnerability scans. It is designed to help verified maintainers receive model-generated security findings by email, including reproducers and candidate patches when available. Enrollment is handled through a GitHub pull request that includes project configuration and a Dockerfile.

Key Features

  • Free periodic security scans for eligible critical open-source repositories
  • Model-generated vulnerability reports delivered to verified maintainers
  • Self-contained reproducers included with reports when available
  • Candidate patches provided when available
  • Maintainer enrollment through a GitHub pull request
  • Project configuration and Dockerfile-based setup
  • Email report delivery with optional OpenPGP encryption
  • Maintainer-controlled pause or opt-out options

Best For

Maintainers of eligible critical open-source repositoriesOpen-source projects that want additional AI-assisted vulnerability reviewTeams that can provide a reproducible Docker-based project setupMaintainers who prefer receiving vulnerability findings by emailProjects seeking candidate patches and reproducers alongside security reports

Pricing

OSS Scanner is described as free for eligible open-source projects. Access appears to depend on eligibility and maintainer enrollment rather than a public paid plan.

Pros & Cons

Pros

  • Free for eligible open-source projects
  • Designed specifically for critical open-source repositories
  • Reports may include reproducers that help maintainers validate findings
  • Candidate patches may reduce the time required to investigate fixes
  • Optional OpenPGP encryption supports more private report delivery
  • Maintainers can pause or opt out of scanning

Cons

  • Availability is limited to eligible open-source projects
  • Findings are model-generated and may require maintainer verification
  • Candidate patches are only provided when available
  • Enrollment requires a GitHub pull request and project setup work
  • Not positioned as a general-purpose commercial code scanning platform

Known limitations

  • Enrollment is limited to established open-source projects with a critical infrastructure or user-security impact; Anthropic reviews eligibility and verifies core maintainers
  • Reports are fully model-generated without human review and can contain incorrect findings or inflated severity ratings
  • Maintainers must supply project configuration and a Dockerfile that builds the project and installs dependencies before an offline audit
  • Scan frequency varies with pipeline load and other factors; reports are delivered by email rather than an on-demand IDE workflow
