Container Desktop vs Testcontainers Desktop

Container Desktop is a free, open-source desktop interface for Podman, Docker, and Apple Container, available on Linux, macOS, and Windows. It connects to local environments, SSH, and WSL. Users can inspect container logs, environment variables, mounts, ports, and live stats, then start, stop, or restart containers. Exposed services can be opened in a browser.

For image work, the app includes a Containerfile editor with live linting, build options, a build timeline, and an image layer inspector. It also provides tools for image security, pods, networks, secrets, and volumes. A built-in assistant can inspect and operate containers; it requests approval before actions that change state. The assistant works with LM Studio and llama.cpp locally, or OpenRouter and Anthropic in the cloud. The project is licensed under MIT. Its privacy policy says the app itself performs no telemetry and collects, stores, or transmits no data, while noting that third-party registries such as docker.io and quay.io have their own privacy practices. Linux and Windows downloads list x86_64 and arm64 options.

Testcontainers Desktop is a companion app for the open source Testcontainers libraries, for local development and testing with real dependencies. The closed-source app runs in the system tray and lets users switch between local container runtimes, including Podman and Colima. It can also run containers through Testcontainers Cloud on demand without local resources or a local Docker daemon. Users can expose services on fixed ports for debugging tools, inspect container logs, and open a shell for a configured service. A beta freeze option can stop containers from shutting down after tests, while session tracking feeds collaborative dashboards with desktop and CI data from an organization. More than 15 example service configurations include PostgreSQL and Kafka. The embedded runtime is beta and requires macOS 11 or later. A Docker account is required to sign in. The free plan includes 300 minutes of cloud runtime per month; Turbo mode requires a paid account.
