Act vs charm

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.

Charm is a set of open-source tools and libraries for building beautiful terminal user interfaces in Go. The ecosystem includes Bubble Tea (TUI framework), Lip Gloss (styling), Glamour (Markdown rendering), and cloud services for data persistence.
