Docker is the original container engine; Colima adds a lightweight VM layer for macOS/Linux with easier setup.
Which to pick
Pick Colima if you want…
- Simple local container runtimes
- A free, open-source tool
- Integrations with QEMU or vmnet (on Colima's list, not Docker's)
Pick Docker if you want…
- Secure sandboxes for AI agents
- Standard container engine
- Integrations with Docker Engine, Docker CLI or Docker Compose (on Docker's list, not Colima's)

Colima features
- Cross-platform support. Runs container runtimes on both macOS and Linux without complex configuration.
- Minimal setup. Installs and starts containers with a single command and default settings.
- Configurable networking. Allows custom NAT66 prefixes for shared vmnet networking, including IPv6 support.
- Foreign-arch emulation. Falls back to QEMU to run containers for architectures not natively supported (e.g., x86_64 on Apple Silicon).
- Multiple instances. Enables creating several Colima instances sharing the same vmnet network.
Docker features
- Docker Sandboxes. MicroVM isolation with locked-down network and filesystem for each agent session.
- Docker AI Governance. Console for policy enforcement, identity-bound audit logs and zero per-machine setup.
- Docker Hardened Images. Minimal, signed images with SLSA Level 3 provenance and continuous patching.
- Docker Desktop. Full dev loop with Engine, Kubernetes, Compose and GUI on local machines.
- Docker Build Cloud. Cloud-based build service with free trial minutes for CI/CD pipelines.
- Testcontainers Cloud. Runtime environment for container-based tests with allocated minutes per plan.
