There’s an active community of members, contributors and collaborators behind the SLSA framework. We’re drawn together by the shared goals of improving software supply chain security and codifying best practices for development, deployment and governance, all collaborating on an objective framework that works for open source projects and organizations, influences policy and regulations, empowers engineers and builds for the future.

Get involved

The SLSA project is an open source project that strives to make useful and practical standards, tools, and documentation to reduce software supply chain risk in the real world. To succeed, we rely on contributors from a variety organizations to help us improve. Whether that’s reporting successes or challenges, contributing changes to the specification or documentation, or developing tooling and services, we welcome your contributions.

“SLSA’s really the first of its kind, a framework for supply chain and build integrity. What sets it apart is the thriving community behind it, and it’s resonating with different organizations.”

Project status

SLSA v1.0 is coming soon!

The SLSA v1.0 release candidate specification is out and available for community review. We anticipate a stable release soon.

We’ve released a set of tools and services to generate up to SLSA 3 provenance, and plan to develop further tooling soon.

Google has been using an internal version of SLSA since 2013 and requires it for all of their production workloads.
