Act vs lazydocker

act is an open-source command-line tool that runs GitHub Actions workflows locally using Docker containers. It reads workflow files from .github/workflows/ and executes them with environment variables and filesystem configurations matching GitHub's hosted runners. The tool enables fast local feedback on workflow changes without requiring commits and pushes to a remote repository.

lazydocker is terminal-based UI for Docker that provides an interactive dashboard for managing containers, images, and volumes. It provides comprehensive features for development workflows. The tool is actively maintained with regular updates and strong community/vendor support.
