OSS Rebuild information
What is OSS Rebuild?
Secure open-source package ecosystems by originating, validating, and augmenting build attestations.
OSS Rebuild aims to apply reproducible build concepts at low-cost and high-scale for open-source package ecosystems.
Rebuilds are derived by analyzing the published metadata and artifacts and are evaluated against the upstream package versions. When successful, build attestations are published for the upstream artifacts, verifying the integrity of the upstream artifact and eliminating many possible sources of compromise.
We currently support the following ecosystems:
- NPM (JavaScript/TypeScript)
- PyPI (Python)
- Crates.io (Rust)
While complete coverage is the aim, only the most popular packages within each ecosystem are currently rebuilt.
