A self-hosted, easy-to-use realtime database for Asp.Net Core and EF Core with automatic API generation.
SapphireDb is a self-hosted realtime database server for Asp.Net Core and EF Core that automatically generates a generic API for realtime data synchronization. It solves the problem of building responsive applications by providing automatic data synchronization between server and multiple client technologies without requiring developers to write extensive backend code.
.NET developers building realtime applications who want Firebase-like functionality with self-hosting capabilities, and teams needing offline support across web and mobile clients.
Developers choose SapphireDb because it provides a complete realtime database solution that integrates seamlessly with existing .NET infrastructure while offering self-hosting control, offline support, and broad client compatibility without vendor lock-in.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Directly integrates with Asp.Net Core and EF Core, allowing reuse of existing DbContext and middleware with minimal changes, as shown in the configuration examples.
Generates a generic API out-of-the-box for realtime data synchronization, reducing backend coding effort and enabling responsive applications across clients.
Works with multiple frontend frameworks like React, Angular, Svelte, and Node.js, demonstrated by dedicated client examples in the README.
Provides built-in offline support where clients can operate without connectivity and sync upon reconnection, crucial for mobile or unstable network environments.
Heavily dependent on Asp.Net Core and EF Core, making it unsuitable for projects using other backend stacks and limiting cross-platform flexibility.
Requires modifying DbContext to derive from SapphireDbContext and configuring middleware in Startup.cs, which adds overhead compared to drop-in solutions.
As a self-hosted alternative, it has a smaller community and fewer third-party integrations than established services like Firebase, potentially affecting support and tooling.
SapphireDb is an open-source alternative to the following products:
Firestore is a flexible, scalable NoSQL cloud database from Firebase for storing and syncing data in real-time across mobile and web apps.
Firebase Realtime Database is a cloud-hosted NoSQL database within Firebase that stores and syncs data in real-time across connected clients.
