Testcontainers Desktop
testcontainers.com
What it is
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.
