The Stitch CLI provides an intuitive way to automate workflows with Stitch, allowing developers to export existing applications, make local edits, and merge changes back into their Stitch app, increasing productivity and collaboration. With the CLI, users can log in, import and deploy stitch applications from a local directory, easily share custom services and functions between apps, push code from development environments to QA and production, and work with standard JSON and JavaScript files and structures. The CLI includes commands such as `login`, `logout`, `whoami`, `export`, and `import` for authentication, importing, and exporting applications, making it easier to develop and manage Stitch apps.
