Retool has announced the general availability of Retool Database, a PostgreSQL database with a spreadsheet interface, designed to streamline the process of building secure and scalable applications. This service allows users to upgrade from spreadsheet-based processes, providing 5GB of free data storage for one year, and features a user-friendly interface that simplifies schema creation and data management. Users can import data from Airtable and Google Sheets by uploading CSV files, and perform direct SQL queries to integrate with Retool applications or external databases. Retool Database supports multiple environments and offers integration with Retool Workflows for automated tasks, alongside compatibility with GPT-4 for natural language data queries. It is available to all cloud customers, with self-hosted customers needing to upgrade to v2.113 or later to access these features.
