Use the Aspire Dashboard Standalone

Source: Dev.to

Quick Tip originally published on lukaswalter.dev.

Overview

Aspire is often seen as a full orchestration suite, but its Dashboard can run standalone.
Use it as a lightweight, OTLP‑compatible viewer for logs, traces, and metrics from any language (C#, Go, Python, etc.) without the overhead of the full suite.

Running the Dashboard

docker run --rm -it \
  -p 18888:18888 \
  -p 4317:18889 \
  -p 4318:18890 \
  --name aspire-dashboard \
  mcr.microsoft.com/dotnet/aspire-dashboard:latest

Ports

Authentication

The dashboard is secured by default. After starting the container, it prints a login URL to the console. Retrieve it with:

docker logs YOUR-CONTAINER-NAME

Look for a line similar to:

Login to the dashboard at http://0.0.0.0:18888/login?t=YOUR_TOKEN_HERE

Instant Setup

• Set your OpenTelemetry exporter to http://localhost:4317 (or http://localhost:4318 for HTTP) and the dashboard will start receiving data immediately.

Key Benefits

• Polyglot – Works with any OTLP‑compatible application, not just .NET.
• Local‑First – Ideal for the “inner loop” of development; no extra infrastructure required.
• Standalone – Provides a beautiful, real‑time UI without needing the full Aspire orchestration stack.
