Buildpacks transform your source code into OCI images
Paketo Buildpacks can run on any platform that supports container images, including Docker and Kubernetes!
Compatible with CI/CD integrations around containers such as CircleCI, Gitlab, Tekton, and much more!
Paketo Buildpacks are leveraged by many application platforms and local development tools including Hashicorp Waypoint, the Pack CLI, Spring Boot, Tilt, and VMware Tanzu Build Service.

Here's how it works

Just bring your app and Paketo Buildpacks will detect what language your app is using, gather the required dependencies, and build it into an image.
