Colima vs Garden

Colima runs container environments on macOS and Linux, with Docker, containerd, Kubernetes and Incus runtime options. Docker compatibility is intended to let existing Docker workflows and tools continue without changes; containerd users can use nerdctl for a Docker-like command line. It can launch a local, single-node k3s cluster, and users can select an exact K3s version. CPU, memory and disk allocations are configurable, and multiple isolated instances can run with different settings. Colima also documents GPU-accelerated AI workloads on Apple Silicon using Krunkit, with model runners supporting Docker AI Registry and HuggingFace; Ramalama also supports Ollama registries. Those workloads require Apple Silicon, macOS 13 or newer, and Krunkit, with at least 8 GB of RAM recommended. The AI containers are isolated from the host filesystem, other containers and network access unless network access is enabled. Colima is free and MIT-licensed, with installation options for macOS and Linux. Incus virtual machines require m3 or newer Apple Silicon.

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.
