Act vs Husky

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.

Husky is a developer-utilities tool that git hooks manager that lets you run linters, tests, and formatters automatically on git commit and push. It is open source software.
