Cloud Native Buildpacks Pack vs Garden

Cloud Native Buildpacks Pack is a free command-line tool for building applications with buildpacks and rebasing the resulting application images. It is maintained by the Cloud Native Buildpacks project and is also available as a Go library. Buildpacks turn application source code into container images that can run on any cloud. Listed capabilities include caching, automatic source detection, modular buildpacks, support for multiple languages and processes, minimal images, reproducible builds and reuse of community buildpacks. Pack supports multi-architecture builds and multiple build-cache backends, and the project lists build-time software bills of materials in CycloneDX, SPDX and Syft JSON formats. The CLI runs on Linux, macOS and Windows; installation options include package managers, container images, scripts and manual installation. Builds need a containerized environment and a daemon such as Docker or Podman, and some setups may need the local Docker socket mounted. The project documents CircleCI, GitLab Auto DevOps and Tekton integrations, as well as kpack for Kubernetes-native builds and image updates. Pack is Apache-2.0 licensed.

Garden is a DevOps automation tool for developing and testing Kubernetes applications. It creates production-like environments for development, testing, and CI on demand, then represents infrastructure, builds, services, and tests in a dependency-aware action graph. Graph-aware caching avoids rerunning unchanged images and tests. Garden Core uses YAML declarations to make workflows reproducible across developer machines and CI, and sync mode live-syncs changes to running deployments. Plugins cover Kubernetes, Helm, Terraform, Pulumi, and local scripts. Its Terraform provider validates and provisions infrastructure and exposes stack outputs to Garden actions; the Pulumi plugin is experimental and deploys stacks in dependency order. Garden Cloud's Remote Container Builder uses managed remote compute and shared Docker layer caches. Garden supports Linux, macOS, Windows, and self-hosted use. It requires Git 2.14 or newer, and local service builds need a local Kubernetes installation. The free tier has limits on build minutes, cache hits, and cache retention. Enterprise is a self-hosted Garden Cloud distribution installed into a customer's Kubernetes infrastructure.
