Don't know what Fusion is? You should! Fusion is your #1 partner in crime if you're building a real-time app (an online app delivering some or all updates in real-time) or a high-load app. Moreover, it plays really well with Blazor and works on MAUI.
Curious to see Fusion in action? Explore [Voxt.ai] – a very new chat app built by the minds behind Fusion.
Voxt fuses real-time audio, live transcription, and AI assistance to let you communicate with utmost efficiency. With clients for WebAssembly, iOS, Android, and Windows, it boasts nearly 100% code sharing across these platforms. Beyond real-time updates, several of its features, like offline mode, are powered by Fusion.
Fusion allows you to build real-time UIs like this one —
and it's nearly as easy as if there were no logic related to real-time
updates at all:
Demonstrates Fusion's core compute service pattern with automatic dependency tracking. The sample simulates a project build system that dynamically recomputes projects when their dependencies are invalidated, showcasing automatic caching and invalidation.
Showcases five progressive implementations of a shopping cart system—from in-memory to multi-host distributed—using Fusion's operations framework and command handlers. Demonstrates how to track product prices and cart totals with real-time updates.
A simple Blazor Server application demonstrating real-time UI updates using Fusion compute services. Includes a counter, weather forecast, and chat service with server-side rendering and WebSocket communication.
Extends HelloBlazorServer with hybrid rendering, supporting both server-side and WebAssembly interactive components with Fusion's compute services for real-time data binding.
A full-featured Blazor application with GitHub OAuth authentication, database persistence (SQLite), and Entity Framework Core integration. Demonstrates multiple compute services including chat, composition, image streaming, and real-time sum calculations.
A comprehensive todo application supporting both single-server and multi-tenant distributed architectures with PostgreSQL, SQL Server, or SQLite backends. Showcases Fusion's database entity resolvers, sharding, backend/API server separation patterns, and RPC streaming.
A minimal client-server chat application using Fusion's RPC framework with WebSocket transport. Demonstrates compute methods, command handlers, and real-time state synchronization between client and server.
Extends MiniRpc with multiple servers using consistent hashing-based routing to distribute chat conversations across servers based on chat ID, demonstrating horizontal scalability patterns.
Demonstrates a dynamic peer-to-peer mesh network where hosts are added and removed at runtime. Fusion's shard mapping automatically routes requests to appropriate hosts for distributed counter services.
See Benchmarks.md for the most recent results.
Compares Fusion services against an identical non-Fusion DAL, measuring both local and remote access throughput.
Benchmarks ActualLab.Rpc against gRPC, SignalR, StreamJsonRpc, MagicOnion, and HTTP (REST), measuring both call and streaming throughput on different payload sizes.
