List and Inspect Applications

This articles illustrates how to list and inspect Spin applications deployed to your Fermyon Wasm Functions account using the spin aka plugin.

List Your Applications

To list all Spin applications deployed to your Fermyon Wasm Functions account, use the spin aka app list command as shown in the following snippet:

$ spin aka app list

Depending on which apps you have deployed to your Fermyon Wasm Functions account, the actual output will differ from the output shown here.

hello-fermyon-wasm-functions
validate-jwt-tokens
query-external-database

By default, spin aka app list will print the name of each Spin application deployed to your Fermyon Wasm Functions account as plain text. Alternatively, you could add the --format flag and change the output format to JSON:

$ spin aka app list --format json

This time, you’ll receive the list of Spin applications as JSON array:

[
  "hello-fermyon-wasm-functions",
  "validate-jwt-tokens",
  "query-external-database"
]

You can also use the --verbose flag to learn more about your apps. Below, you’ll see the spin app names alongside their respective app ids.

$ spin aka apps list --verbose
hello-fermyon-wasm-functions(25a5fd1e-d476-40fd-bc54-6cee0e846540)
validate-jwt-tokens(8d8ffd7d-57fe-4c0e-b982-251542db8792)
query-external-database(b6cc1427-392c-4f96-859d-bb4d0adc216c)

Inspecting an Application

Use the spin aka app status command, to gather fundamental information about a Spin application deployed to your Fermyon Wasm Functions account. The command will provide the status of the application your workspace is linked to. Alternatively, you can specify a specific app with the --app-name flag.

$ spin aka app status

Name: hello-fermyon-wasm-functions
ID: ec8a19d8-6d10-4056-bb69-cc864306b489

As you can see, you’ll also receive the public origin, which could be used to access the Spin application. Similar to the spin aka apps list command, you could add the --format json flag to make the command return fundamental information about a particular application as JSON object:

$ spin aka apps info --name hello-fermyon-wasm-functions --format json

{
  "id": "ec8a19d8-6d10-4056-bb69-cc864306b489",
  "name": "hello-fermyon-wasm-functions",
  "urls": [
    "https://ec8a19d8-6d10-4056-bb69-cc864306b489.aka.fermyon.tech"
  ],
  "created_at": "2025-05-23 16:11:49 UTC",
  "invocations": "229 in the past 7 days"
}
