# Cloud Native Buildpacks

**Canonical:** https://apis.io/providers/buildpacks/  
**Website:** https://buildpacks.io  
**APIs profiled:** 3

Cloud Native Buildpacks (CNBs) transform application source code into OCI-compliant container images that can run on any cloud, without requiring Dockerfiles. Initiated by Pivotal and Heroku in January 2018, CNBs are a CNCF incubating project licensed under Apache-2.0. They centralize container expertise through composable buildpacks, enable layer rebasing for efficient OS updates, and generate Software Bills of Materials (SBOM). The pack CLI and kpack platform operator are primary integration points.
