## What's under the hood?

1. **Frappe Framework**: A full-stack web application framework written in Python and Javascript. The framework provides a robust foundation for building web applications, including a database abstraction layer, user authentication, and a REST API.
2. **Frappe UI**: A Vue-based UI library to provide a modern user interface. The Frappe UI library provides a variety of components that can be used to build single-page applications on top of the Frappe Framework.
3. **Agent**: A flask app designed to work along with Press. It provides a CLI interface for Press to communicate with the sites and benches.
4. **Docker**: An open-source platform that enables developers to build, package, and deploy applications in lightweight, portable containers.
5. **Ansible**: An open-source IT automation tool that simplifies the management, configuration, and deployment of systems and applications.
