HttpInspector.AspNetCore

NuGet Publish NuGet

HttpInspector.AspNetCore turns any ASP.NET Core app into its own request/response inspector. Drop it in, capture structured JSON logs (headers, bodies, timings, correlation IDs), and browse traffic through a zero-config dashboard.

  • One-line wiring: AddHttpInspector + UseHttpInspector, no controllers or static files required.
  • Built-in UI: /http-inspector hosts an auto-refreshing grid with filters, status coloring, and paired request/response views.
  • Pluggable storage: ships with a JSONL file store, but you can swap in your own IHttpInspectorStore.
  • Production-friendly: path filters, header redaction, optional auth, and SourceLink-enabled NuGet artifacts.

NuGet package: https://www.nuget.org/packages/HttpInspector.AspNetCore/

Quick Start

var builder = WebApplication.CreateBuilder(args);

// Register HTTP inspector dependecies 👇
#if DEBUG
builder.Services.AddHttpInspector();
#endif

var app = builder.Build();

// Enable it as part of the ASP.NET Core pipeline 👇
#if DEBUG
app.UseHttpInspector();
#endif

app.Run();

That's it! You can now visit /http-inspector to open the UI or GET /http-inspector/stream?since=<timestamp> for raw JSON events.

Configuring log retention

Configure rolling files without touching DI by passing a lambda to UseHttpInspector:

app.UseHttpInspector(store =>
{
    store.MaxFileSizeBytes = 5 * 1024 * 1024; // 5 MB per file
    store.RetainedFileCount = 4;              // keep 4 rolled files
    store.RetainedDays = 14;                  // purge anything older than two weeks
});

Leave the lambda out to stick with the built-in defaults.

HttpInspector writes JSONL segments with the entry timestamp baked into each filename (for example httpinspector-log-20250105T173000123Z.jsonl). When you pass a since query value the stream endpoint maps that timestamp directly to the right file and performs a binary search inside the JSONL document, so only the relevant portion of the log is read. You can optionally send an until parameter as well (for example /http-inspector/stream?since=2025-01-01T00:00:00Z&until=2025-01-02T00:00:00Z) to cap the range.
