Build Full-Stack Applications in Pure C#

Ivy is a modern C# framework that lets you build reactive full-stack web applications entirely in pure C# - using familiar React-style components, hooks, and declarative patterns. No frontend/backend split, no HTML/CSS/JS - just write type-safe C# code and ship beautiful, production-ready internal tools at lightning speed.

Quick Start   •   Docs   •   Samples   •   Examples   •   Current Sprint   •   Roadmap

Simple Example

Ivy takes a lot of inspiration from frameworks like React. If you know React, you'll feel right at home. Here's a simple counter app built with Ivy:

public class SimpleCounterApp : ViewBase
{
   public override object? Build()
   {
       var count = UseState(0);
       
       UseEffect(() =>
       {
           Console.WriteLine($"Count changed to: {count.Value}");
       }, [count]);

       return Layout.Vertical(
           Text.Block($"Count: {count.Value}"),
           new Button("Increment", onClick: _ => count.Set(count.Value + 1))
       );
   }
}

Features

⚙️ Architecture

  • Rich Widget Library: Extensive set of pre-built widgets to build any app. If you need more, an external widget framework is coming soon, where you can integrate any React, Angular, or Vue component.
  • External Widget Framework: Easily integrate any third-party React component.
  • Hooks: Familiar React-style hooks for state management, side effects, and lifecycle events.

🎨 UI Components

  • Forms: Create complex CRUD forms with validation and data binding.
  • Data Tables: Sort, filter, and paginate data.
  • Charts/Dashboards: Build interactive charts and dashboards with ease.

⚡ Developer Experience

  • Hot-Reloading: Full support for hot-reloading with maintained state as much as possible.
  • LLM Code-Generation Compatibility: Designed to maximize compatibility with LLM code generation tools.

Ivy maintains state on the server and sends updates over WebSocket. The frontend consists of a pre-built React-based rendering engine. With Ivy, you never need to touch any HTML, CSS, or JavaScript. Only if you want to add your own widgets.

Tools

The Ivy.Console CLI provides a suite of tools to streamline your development workflow:

🚀 Getting Started

  • Project Initialization: Quickly set up new Ivy projects with predefined templates.
  • AI-Powered App Generation: Generate applications using AI based on your specifications.
  • MCP: Teach any coding agent to use Ivy Framework for building full-stack applications.

🔌 Integrations

  • Authentication: Built-in support for popular authentication providers like Supabase, Auth0, Clerk, and Microsoft Entra.
  • Database: Easy integration with SQL Server, Postgres, Supabase, MariaDB, MySQL, Airtable, Oracle, Google Spanner, Clickhouse, Snowflake, and BigQuery.

📦 Production

  • Deployment Management: Manage deployments to Azure, AWS, Google Cloud, or Sliplane with ease.
  • Secrets Management: Securely manage sensitive information within your applications.

Usage

Quick Start

⚠️ Note: Ivy.Console is still in beta, and the agentic features require an account. Register for a free account to be among the first to try these features.

Make sure you have the .NET 10 SDK installed.

  1. Install Ivy CLI:

    dotnet tool install -g Ivy.Console

  2. Install Vite+ CLI: Ivy uses the vp (Vite+) CLI for frontend orchestration. Install it globally:

    npm install -g vite-plus

  3. Create a new project:

     ivy init --hello

  4. Run:

    ivy run --browse

  5. Open http://localhost:5010 in your browser.

You can also run ivy samples to see all the components that Ivy offers and ivy docs for documentation.
