.NET Error Tracking: 4 Tools Compared for 2026

What .NET Error Tracking Should Capture

For an ASP.NET Core service, useful error tracking starts with unhandled exceptions, readable C# stack traces, request context, environment, release, and user-safe diagnostic tags. Logs still matter, but a hosted tracker adds grouping and an issue lifecycle so repeated exceptions do not become repeated manual investigations.

Before comparing dashboards, verify that the notifier supports your deployed runtime and test one exception from a non-production environment. Also decide which request fields must be removed before they leave your application.

.NET Error Tracking Tools Compared

Feature sets and supported runtime versions change. Confirm the current vendor documentation against the exact .NET version and hosting model you deploy.

Bugsly with ASP.NET Core

Bugsly accepts the Sentry event protocol, so a .NET service can use the maintained Sentry NuGet package and point it at the DSN shown in the Bugsly project setup. This is compatibility with the Sentry SDK; Bugsly does not claim a separate native .NET package.

dotnet add package Sentry.AspNetCore

var builder = WebApplication.CreateBuilder(args);

builder.WebHost.UseSentry(options =>
{
    options.Dsn = builder.Configuration["BUGSLY_DSN"];
    options.Environment = builder.Environment.EnvironmentName;
    options.SendDefaultPii = false;
});

Keep the DSN in configuration, set a release identifier during deployment, and send a controlled test exception before relying on production alerts. Existing Sentry-instrumented applications can normally evaluate Bugsly by changing the DSN rather than replacing their instrumentation.

Sentry for .NET

Sentry maintains the SDK used in the example above and documents integrations across .NET application types. It is the clearest default when you want the broad Sentry platform or need vendor-native support for Sentry-specific tracing and profiling features. Check the support matrix separately for error monitoring and profiling because they do not cover every runtime in the same way.

Rollbar for .NET

Rollbar publishes a core .NET notifier plus separate modules for ASP.NET, ASP.NET MVC, Web API, ASP.NET Core, Microsoft.Extensions.Logging, Serilog, NLog, and log4net. That modular design is useful when an application already standardizes on one of those logging abstractions, but it also means the package choice should match the framework rather than copying a generic install command.

Honeybadger for .NET

Honeybadger documents a Honeybadger.DotNetCore package for ASP.NET Core, automatic unhandled-exception reporting, manual notifications, and a Microsoft.Extensions.Logging provider. It is a straightforward option when the main requirement is exception reporting from a modern ASP.NET Core application.

How to Choose

• Choose Bugsly when Sentry SDK compatibility and a focused error workflow are the priority.
• Choose Sentry when you need its broader native monitoring feature set.
• Choose Rollbar when its modular .NET and logging-framework integrations fit an existing stack.
• Choose Honeybadger when you want a direct ASP.NET Core middleware and logging-provider setup.

Whichever tool you test, compare it with the same exception, release tag, environment, and scrubbed request context. The useful winner is the one your team can configure safely and use to resolve a real production failure—not the one with the longest feature list.
