OSS Index and Guide: Continuity and Clarity

OSS Index played a critical role by providing free, high-quality vulnerability intelligence for many developers and organizations. But it was built for a world where humans were in the loop. Today's AI-driven software supply chains require something different: real-time, continuously curated intelligence that automated systems can safely rely on. While software development has fundamentally changed, one thing hasn't. Teams are still accountable for what ships to production. Sonatype Guide helps ensure builds are secure in an era of where open source risk continues to scale exponentially. 

What to Expect: 

  • The OSS Index API will continue to be available via compatibility API in Sonatype Guide.
  • Users can expect continued compatibility with existing integrations such as Dependency-Track and Dependency-Check.
  • Free and paid packages will be offered, scaling based on usage and consumption needs.
  • Users will have clear options to continue using OSS Index or transition to Guide as needs evolve.

Guide provides a path forward for teams looking to fully automate open source security in AI-powered SDLCs. Our goal is to make this transition clear, predictable, and non-disruptive while supporting the realities of modern, AI-assisted development.
