.NET Aspire dashboard overview
.NET Aspire project templates offer a sophisticated dashboard for comprehensive app monitoring and inspection, and it's also available in standalone mode. This dashboard allows you to closely track various aspects of your app, including logs, traces, and environment configurations, in real-time. It's purpose-built to enhance the development experience, providing an insightful overview of your app's state and structure. The dashboard exposes the ability to stop, start, and restart resources, as well as view and interact with logs and telemetry.
Use the dashboard with .NET Aspire projects
The dashboard is integrated into the .NET Aspire *.AppHost. During development the dashboard is automatically launched when you start the project. It's configured to display the .NET Aspire project's resources and telemetry.
For more information about using the dashboard during .NET Aspire development, see Explore dashboard features.
Standalone mode
The .NET Aspire dashboard is also shipped as a Docker image and can be used standalone, without the rest of .NET Aspire. The standalone dashboard provides a great UI for viewing telemetry and can be used by any application.
docker run --rm -it -p 18888:18888 -p 4317:18889 -d --name aspire-dashboard \
mcr.microsoft.com/dotnet/aspire-dashboard:9.0
The preceding Docker command:
- Starts a container from the
mcr.microsoft.com/dotnet/aspire-dashboard:9.0image. - The container instance exposing two ports:
- Maps the dashboard's OTLP port
18889to the host's port4317. Port4317receives OpenTelemetry data from apps. Apps send data using OpenTelemetry Protocol (OTLP). - Maps the dashboard's port
18888to the host's port18888. Port18888has the dashboard UI. Navigate tohttp://localhost:18888in the browser to view the dashboard.
- Maps the dashboard's OTLP port

Architecture
The dashboard user experience is built with a variety of technologies. The frontend is built with 📦 Grpc.AspNetCore) NuGet package NuGet package) to the resource server. Consider the following diagram that illustrates the architecture of the .NET Aspire dashboard:
Security
The .NET Aspire dashboard offers powerful insights to your apps. The UI displays information about resources, including their configuration, console logs and in-depth telemetry.
Data displayed in the dashboard can be sensitive. For example, configuration can include secrets in environment variables, and telemetry can include sensitive runtime data. Care should be taken to secure access to the dashboard.
