SharpInspect

Chrome DevTools-style inspector for any .NET application

Monitor HTTP requests, console logs, performance metrics, and application info in real-time.

English | 한국어

Features

• Framework Agnostic: Works with WinForms, WPF, Console, ASP.NET Core, and more
• One-Line Setup: Start with SharpInspectDevTools.Initialize()
• Real-Time Monitoring: WebSocket-powered live data streaming
• Chrome DevTools UI: Familiar, intuitive interface
• Zero Dependencies: No external NuGet packages required
• Development-Only by Default: Automatically disabled in production environments

Supported Platforms

Quick Start

1. Install

dotnet add package SharpInspect

2. Initialize

using SharpInspect;

// Initialize at app startup
SharpInspectDevTools.Initialize();

// Or with options
SharpInspectDevTools.Initialize(options =>
{
    options.Port = 9229;
    options.AutoOpenBrowser = true;
});

3. Open in Browser

http://localhost:9229

Usage Examples

Console App

using SharpInspect;

class Program
{
    static async Task Main()
    {
        SharpInspectDevTools.Initialize();

        // Create HttpClient with automatic capture
        using var client = SharpInspectDevTools.CreateHttpClient();

        // HTTP requests appear in DevTools Network tab
        var response = await client.GetStringAsync("https://api.example.com/data");

        // Console output appears in DevTools Console tab
        Console.WriteLine("Data received!");

        SharpInspectDevTools.Shutdown();
    }
}

WinForms / WPF

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        SharpInspectDevTools.Initialize();
        base.OnStartup(e);
    }

    protected override void OnExit(ExitEventArgs e)
    {
        SharpInspectDevTools.Shutdown();
        base.OnExit(e);
    }
}

Using Statement (Auto-Shutdown)

using (new SharpInspectSession())
{
    // Your app logic
    // Automatically shuts down when block exits
}

Configuration

SharpInspectDevTools.Initialize(options =>
{
    // Server
    options.Port = 9229;
    options.Host = "localhost";
    options.AutoOpenBrowser = true;
    options.OpenInAppMode = true;  // Opens as standalone window (Chrome/Edge)

    // Capture toggles
    options.EnableNetworkCapture = true;
    options.EnableConsoleCapture = true;
    options.EnablePerformanceCapture = true;
    options.EnableApplicationCapture = true;

    // Storage limits (ring buffer)
    options.MaxNetworkEntries = 1000;
    options.MaxConsoleEntries = 5000;
    options.MaxPerformanceEntries = 2000;
    options.MaxBodySizeBytes = 1048576;  // 1MB

    // Development-only mode (enabled by default)
    options.EnableInDevelopmentOnly = true;
    options.DevelopmentDetectionMode = DevelopmentDetectionMode.Auto;

    // Security
    options.MaskedHeaders.Add("X-API-Key");
    options.AccessToken = "my-secret-token";
});

Development Detection Modes

SharpInspect runs only in development environments by default:

// Auto (default): Environment variable first, then debugger attached
options.DevelopmentDetectionMode = DevelopmentDetectionMode.Auto;

// Environment variable only: DOTNET_ENVIRONMENT or ASPNETCORE_ENVIRONMENT = "Development"
options.DevelopmentDetectionMode = DevelopmentDetectionMode.EnvironmentVariableOnly;

// Debugger only: Debugger.IsAttached
options.DevelopmentDetectionMode = DevelopmentDetectionMode.DebuggerOnly;

// Custom: Your own logic
options.DevelopmentDetectionMode = DevelopmentDetectionMode.Custom;
options.CustomDevelopmentCheck = () => MyConfig.IsDevMode;

// Force enable in all environments
options.EnableInDevelopmentOnly = false;

DevTools UI Features

Network Tab

• Request/response list with timing info
• Full path display (pathname + querystring)
• Status code color coding (2xx green, 4xx orange, 5xx red)
• Headers and body inspection (JSON formatted)
• Timing breakdown (DNS, TCP, TLS, TTFB)
• Filtering and search
• Clear button
• Export HAR: Export network logs as HAR (HTTP Archive) format
• Copy as cURL/fetch: Copy request as cURL command or fetch code

Console Tab

• Log level color coding
• Real-time streaming
• Stack trace display for exceptions
• Filtering and search

Performance Tab

• CPU usage monitoring
• Memory metrics (working set, GC heap)
• GC collection counts
• Thread count tracking
• Request Stats: Requests/sec, avg response time, error rate, uptime

Application Tab

• App info (name, version, runtime, PID)
• Environment variables
• Loaded assemblies list

Security Considerations

• Binds to localhost only by default
• Auto-disabled in production (EnableInDevelopmentOnly = true)
• Sensitive headers masked automatically (Authorization, Cookie)
• Optional token-based authentication

Roadmap

Completed

• Network Tab (HTTP capture with timing)
• Console Tab (log capture)
• Performance Tab (CPU, memory, GC metrics)
• Application Tab (app info, env vars, assemblies)
• Real-time WebSocket streaming
• Chrome DevTools-style UI
• Development-only mode with multiple detection strategies
• Multi-framework support (.NET Framework 4.6.2 ~ .NET 9.0)
• Dark mode UI
• HAR export
• Request Stats (requests/sec, avg response time, error rate)
• Frontend modularization (separate HTML/CSS/JS files)
• Network panel UX improvements (full path display, error status)
• NuGet package release

Planned

• Custom panel plugin system
• Request replay
• Performance timeline view
