What Testcontainers Desktop is
Testcontainers Desktop is a companion app for the open-source Testcontainers libraries, designed to support local development and testing with real dependencies. It runs in the system tray and lets users switch among local container runtimes such as Podman and Colima. It can also run containers through Testcontainers Cloud on demand, without using local resources or requiring a local Docker daemon. For debugging, users can expose container services on fixed ports, review logs, or open a shell for a configured service. Its beta freeze feature can pause container shutdown after tests so containers remain available for inspection. The app tracks test sessions and offers collaborative dashboards with data from desktop and CI users in an organization. It includes more than 15 sample service configurations, including PostgreSQL and Kafka. The embedded runtime is in beta and available on macOS 11 or later. Testcontainers Desktop supports Compose workflows and IDE integration, but requires Docker account sign-in. The free plan includes 300 minutes of cloud runtime per month; Turbo mode requires a paid account.
