Retool utilizes the Neon API to efficiently manage over 300,000 Postgres databases with minimal engineering resources, demonstrating the potential of serverless architecture and automated database management. By integrating Neon's serverless Postgres solutions, which automatically scale to zero when inactive, Retool minimizes idle resource costs and manages a vast database fleet with just one engineer. Retool's platform, known for enabling rapid internal app development through its drag-and-drop interface, seamlessly integrates these databases, allowing developers to focus on building custom internal tools without the burden of database management. Retool's internal operations are enhanced by using its own platform to oversee database tasks, showcasing the benefits of their approach to potential partners and customers interested in offering managed Postgres solutions.
