Why Fulora

You have a fast-moving web team and a battle-tested .NET desktop stack.
Most hybrid approaches force a compromise: either weak host-web contracts, or a rewrite when complexity grows.

Fulora is built for the middle path that scales:

• Keep your native host in C# and Avalonia
• Ship rich UI with React/Vue/Svelte inside WebView
• Connect both sides through a typed, source-generated bridge
• Enforce host capabilities through policy-first execution

From "just embed one page" to "run a full product shell", you stay on one runtime model.

Start in 60 Seconds

Choose the onboarding path that matches where you are today.

Recommended (CLI + template):

dotnet tool install -g Agibuild.Fulora.Cli
dotnet new install Agibuild.Fulora.Templates
fulora new MyApp --frontend react
cd MyApp
fulora dev

Alternative (template only):

dotnet new install Agibuild.Fulora.Templates
dotnet new agibuild-hybrid -n MyApp
cd MyApp
dotnet run --project MyApp.Desktop

Manual (add WebView to an existing Avalonia app):

dotnet add package Agibuild.Fulora.Avalonia

In Program.cs:

AppBuilder.Configure<App>()
 .UsePlatformDetect()
 .UseFulora()
 .StartWithClassicDesktopLifetime(args);

In XAML:

<Window xmlns:wv="clr-namespace:Agibuild.Fulora;assembly=Agibuild.Fulora">
 <wv:WebView x:Name="WebView"
 Source="https://example.com" />
</Window>

Speak One Language Across C# and JavaScript

The bridge is the core experience: predictable contracts, async-friendly calls, and no fragile string-based IPC.

Expose C# to JavaScript:

[JsExport]
public interface IGreeterService
{
 Task<string> Greet(string name);
}

webView.Bridge.Expose<IGreeterService>(new GreeterService());

Call from JavaScript:

const msg = await window.agWebView.rpc.invoke("GreeterService.greet", {
 name: "World"
});

Call JavaScript from C#:

[JsImport]
public interface INotificationService
{
 Task ShowNotification(string message);
}

var notifications = webView.Bridge.GetProxy<INotificationService>();
await notifications.ShowNotification("File saved!");

Ship SPAs Like Native Screens

Run your frontend exactly how your team already works: embedded assets in production, hot reload in development.

Production (embedded):

webView.EnableSpaHosting(new SpaHostingOptions
{
 EmbeddedResourcePrefix = "wwwroot",
 ResourceAssembly = typeof(MainWindow).Assembly,
});
await webView.NavigateAsync(new Uri("app://localhost/index.html"));

Development (HMR):

webView.EnableSpaHosting(new SpaHostingOptions
{
 DevServerUrl = "http://localhost:5173"
});

Capability Snapshot

From a single embedded page to a full product shell — everything you need is already here.

Core

• Typed bridge: [JsExport] / [JsImport], source-generated C#/JS proxies, AOT-safe; V2: byte[]/Uint8Array, CancellationToken/AbortSignal, IAsyncEnumerable streaming, overloads
• Typed capability gateway for host/system operations (policy-first execution)
• SPA hosting: embedded assets, dev HMR proxy, shell activation, deep-link, SPA asset hot update with signature verification
• OAuth / Web auth (IWebAuthBroker), Web dialog (IWebDialog), screenshot & PDF, cookies, command manager
• DevTools, User-Agent, session modes, dependency injection

Ecosystem

• Official plugins: Database (SQLite), HTTP Client, File System, Notifications, Auth Token, Biometric, LocalStorage
• CLI: fulora new, dev, generate, search, add plugin, list plugins --check
• Telemetry: OpenTelemetry provider, Sentry crash reporting with bridge breadcrumbs
• AI: Microsoft.Extensions.AI integration, streaming, tool calling, Ollama/OpenAI providers
• Enterprise: OAuth PKCE client, shared state store (cross-WebView), plugin compatibility matrix

Vision & Roadmap

Fulora helps teams move from first WebView integration to full hybrid platform without replacing their foundation.

Two paths, one runtime:

• Control path: integrate WebView with minimal coupling
• Framework path: adopt bridge, policy, shell, and tooling for faster delivery

Unlike wrapper-only solutions, Fulora provides typed host/web contracts, policy-governed capabilities, machine-checkable diagnostics, and scalable app-shell patterns out of the box.

Current status: Phase 12 (Enterprise & Advanced Scenarios) completed. All roadmap phases through 12 are done.

Quality Signals

Quality badges at the top of the page are updated automatically by CI on every successful build to main from these CI gates:

nuke Test # Unit + Integration
nuke Coverage # Coverage report + threshold enforcement
nuke NugetPackageTest # Pack → install → run smoke test

For local template validation (not required by the default CI badge pipeline):

nuke TemplateE2E # Template end-to-end test
