InstantDB

InstantDB is a client-side database designed to simplify backend development for frontend engineers. It provides a comprehensive set of features including queries, transactions, authentication, permissions, storage, real-time updates, and offline support, all accessible through a simple SDK that can be used directly in the browser. This eliminates the need for developers to build common, non-differentiating backend components, allowing them to focus on their application's unique business logic. The platform is built to deliver modern app experiences with real-time interactions, minimal loading screens, collaborative features, and robust offline capabilities. It handles complex data operations like optimistic updates and rollbacks automatically. InstantDB also supports multi-tenancy, enabling rapid database provisioning, and is designed to be highly scalable and efficient for both human-built applications and AI agents.
