Docker Desktop vs Testcontainers Desktop

Docker Desktop brings container development and deployment tools together for developers and teams. It includes Docker Engine, Docker CLI, Docker Compose, Docker Build, and Docker Kubernetes, with support for building images and Compose workflows. Its built-in Kubernetes environment lets users deploy, scale, test, and manage containerized applications locally without an external cluster. Docker Debug offers command-line diagnostics for containers and images, including slim containers, while Extensions allow third-party tools for debugging, testing, security, and networking. Downloads cover macOS with Apple Silicon or Intel, Windows with AMD64 or ARM64, and Linux; web is also listed as a platform. Docker Personal is free. Pro is $9 a month, Team is $15 a month, and Business is $24 a month. Paid-plan allowances and user limits differ. Business lists VDI support and additional security controls. Commercial use at companies with more than 250 employees or more than $10 million in annual revenue requires a paid subscription.

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.
