## Introduction Supabase is an open-source Firebase alternative that provides a complete backend solution for building web and mobile applications. It offers a suite of tools and services, including a PostgreSQL database, authentication, storage, and real-time subscriptions, all accessible through a simple API. ## Quick Start To use the Supabase Playground, follow these steps: 1. Visit the GetVM website and access the Supabase Playground environment. 2. The Playground provides a pre-configured Supabase project, where you can explore the various features and functionalities. 3. In the Playground, you can interact with the Supabase API using the provided code examples and documentation. 4. Try creating a new table, inserting data, querying the database, and exploring the authentication and storage features. 5. The Playground also includes a web-based SQL editor, allowing you to write and execute SQL queries directly. The Supabase Playground is a free, limited-use environment, with restrictions on the amount of data, number of API calls, and other usage limits compared to a full Supabase project. Any changes or data you create will not be saved, as the Playground is intended for learning and experimentation purposes only. ## Configurations and Usage The Supabase Playground provides Container-based VMs with 1 core and 2GB RAM, and storage up to 10GB. VMs can be used for a default time of 30 minutes, with a reminder after 20 minutes of use. After the session, VMs will be deleted. Pro users have 5GB of persistent storage to save their code and files, which is automatically mounted to the /home/getvm/project/storage directory on VM startup. Any files saved in this directory will be preserved and accessible across VMs. Please note that internet access is restricted on the Free plan to prevent misuse, and VMs should be used for learning and experimentation within the provided resource limits. Avoid using VMs for cryptocurrency mining or engaging in illegal activities. ## Discord Welcome to the GetVM Discord server!
