Ivy-Interactive/Ivy-Framework

What it solves

Ivy eliminates the need for a separate frontend and backend stack when building web applications. It allows developers to create full-stack, reactive apps using only C#, removing the requirement to write HTML, CSS, or JavaScript while maintaining a modern, component-based development experience.

How it works

Ivy uses a server-side state management system that communicates updates to a pre-built React-based rendering engine on the frontend via WebSockets. It adopts a React-like programming model with components and hooks (e.g., UseState, UseEffect) implemented in C#. To optimize performance, the core uses Rust-compiled native libraries for JSON diffing and document processing.

Who it’s for

C# developers who want to build production-ready internal tools and full-stack applications quickly without switching between different languages or managing complex frontend/backend API boundaries.

Highlights
