aspire ps command

aspire ps - List running Aspire AppHosts.

Aspire CLI
aspire ps [options]

The aspire ps command lists all running Aspire AppHost processes. The output includes the AppHost project path, process IDs, and dashboard URLs for each running instance.

The command scans for running AppHosts by checking the backchannel connections in the ~/.aspire/backchannels/ directory. This approach is fast because it doesn’t need to recursively search for project files.

The default output is a human-readable table with the following columns:

ColumnDescription
PATHThe file path to the AppHost project
PIDThe process ID of the running AppHost
CLI_PIDThe process ID of the CLI that started the AppHost
DASHBOARDThe dashboard URL with login token

In-scope AppHosts (those within the current directory) are displayed first, followed by out-of-scope AppHosts.

The following options are available:

  • --format <Json|Table>

    Output result format. Use Json for machine-readable output suitable for scripting and automation. The JSON output includes an array of AppHost objects with appHostPath, appHostPid, cliPid, and dashboardUrl properties. Defaults to Table.

  • -?, -h, --help

    Prints help and usage documentation for the available commands and options.

  • -l, --log-level <Critical|Debug|Error|Information|None|Trace|Warning>

    Set the minimum log level for console output. Use this option to increase diagnostics while troubleshooting or reduce output in scripted runs.

  • --non-interactive

    Run the command in non-interactive mode, disabling all interactive prompts and spinners.

  • --nologo

    Suppress the startup banner and telemetry notice.

  • --banner

    Display the animated Aspire CLI welcome banner.

  • --wait-for-debugger

    Wait for a debugger to attach before running a command.

  • List all running AppHosts in table format:

    Aspire CLI
    aspire ps

    Example output:

    Output
    PATH PID CLI_PID DASHBOARD
    ./src/MyApp.AppHost/MyApp.AppHost.csproj 12345 12340 https://localhost:17244/login?t=abc123
    /home/user/other/OtherApp.AppHost.csproj 67890 67885 https://localhost:17250/login?t=def456
  • Output running AppHosts as JSON for scripting:

    Aspire CLI
    aspire ps --format Json

    Example output:

    Output
    [
    {
    "appHostPath": "./src/MyApp.AppHost/MyApp.AppHost.csproj",
    "appHostPid": 12345,
    "cliPid": 12340,
    "dashboardUrl": "https://localhost:17244/login?t=abc123"
    }
