+title: aspire ls command
+seoTitle: aspire ls CLI command reference for discovering AppHosts
+description: Learn about the aspire ls command which discovers and lists AppHost project candidates in the current directory and its subdirectories.
+---
+
+import Include from '@components/Include.astro';
+
+## Name
+
+`aspire ls` - List AppHost project candidates.
+
+## Synopsis
+
+```bash title="Aspire CLI"
+aspire ls [options]
+```
+
+## Description
+
+The `aspire ls` command discovers and lists [AppHost project](/get-started/app-host/) candidates in the current working directory and its subdirectories. It performs parallel discovery and reports results along with each candidate's programming language and build status.
+
+The default output is a human-readable table with the following columns:
+
+| Column     | Description                                                                       |
+| ---------- | --------------------------------------------------------------------------------- |
+| `PATH`     | The file path to the AppHost project                                              |
+| `LANGUAGE` | The raw AppHost language ID, such as `csharp` or `typescript/nodejs`              |
+| `STATUS`   | Build status of the AppHost candidate: `buildable` or `possibly-unbuildable`      |
+
+The `STATUS` value is `buildable` when the project validates as an AppHost candidate. It is `possibly-unbuildable` when the project looks like an AppHost but may not build in the current environment.
+
+### Discovery and configuration
+
+If a configuration file (for example `aspire.config.json` with `appHost.path` or a legacy `.aspire/settings.json` with `appHostPath`) points to an AppHost project, that path is included as a candidate. When a configured AppHost path points to a missing file, `aspire ls` displays a warning. When the configuration file is invalid JSON, has an invalid shape, or the configured AppHost path is empty, contains invalid characters, or isn't a JSON string, `aspire ls` displays an error. When no configuration file is present, discovery continues silently.
+
+### Output ordering
+
+**Non-streaming mode** (`--format json` without `--stream`): results are sorted by path before output.
+
+**Streaming mode** (`--format json --stream`): results are emitted in arrival order from parallel discovery and are **not sorted**. If you need a deterministic order for streamed output, pipe through a sort step. For example:
+
+```bash title="Aspire CLI"
+aspire ls --format json --stream | jq -s 'sort_by(.path)'
+```
+
+This example uses [jq](https://jqlang.org/), a third-party JSON processor.
+
+## Options
+
+The following options are available:
+
+- **`--format <Json|Table>`**
+
+  Output result format. Use `Json` for machine-readable output suitable for scripting and automation. Defaults to `Table`.
+
+- **`--stream`**
+
+  Output discovered AppHosts as newline-delimited JSON (NDJSON), emitting each candidate as soon as it is discovered. Requires `--format json`.
+
+- **`--all`**
+
+  Include all candidate AppHosts by disabling Git filtering and the built-in skip list for common dependency, build-output, and tooling directories such as `bin`, `obj`, `node_modules`, `.venv`, `.git`, and `.vs`. The NuGet package cache is still excluded.

+
+## Examples
+
+- List all discovered AppHost candidates in table format:
+
+  ```bash title="Aspire CLI"
+  aspire ls
+  ```
+
+  Example output:
+
+  ```text title="Output"
+  PATH                                                  LANGUAGE           STATUS
+  ./src/MyApp.AppHost/MyApp.AppHost.csproj              csharp             buildable
+  ./src/OtherApp.AppHost/apphost.ts                     typescript/nodejs  buildable
+  ```
+
+- Output discovered AppHosts as JSON for scripting:
+
+  ```bash title="Aspire CLI"
+  aspire ls --format json
+  ```
+
+  Example output:
+
+  ```json title="Output"
+  [
+    {
+      "path": "./src/MyApp.AppHost/MyApp.AppHost.csproj",
+      "language": "csharp",
+      "status": "buildable"
+    },
+    {
+      "path": "./src/OtherApp.AppHost/apphost.ts",
+      "language": "typescript/nodejs",
+      "status": "buildable"
+    }
+  ]
+  ```
+
+- Stream discovered AppHosts as newline-delimited JSON:
+
+  ```bash title="Aspire CLI"
+  aspire ls --format json --stream
+  ```
+
+  Example output (each line is a JSON object emitted as candidates are discovered; your line order may vary):
+
+  ```text title="Output"
+  {"path":"./src/OtherApp.AppHost/apphost.ts","language":"typescript/nodejs","status":"buildable"}
+  {"path":"./src/MyApp.AppHost/MyApp.AppHost.csproj","language":"csharp","status":"buildable"}
+  ```
+
+  Note: lines are emitted in discovery arrival order and are not sorted. To sort streamed output by path:
+
+  ```bash title="Aspire CLI"
+  aspire ls --format json --stream | jq -s 'sort_by(.path)'
+  ```
+
+- Include all AppHost candidates, ignoring `.gitignore` and directory filters:
+
+  ```bash title="Aspire CLI"
+  aspire ls --all
+  ```
