The number of apps has reached the limit of your…

Error message

The number of apps has reached the limit of your subscription.

What it means

HTTP 403 from `cloud_edition_billing_resource_check("apps")`. When `resource == "apps"` and `0 < apps.limit <= apps.size`, the decorator aborts with `The number of apps has reached the limit of your subscription.` App creation is blocked at the plan's app count ceiling.

Solutions

1. Upgrade the workspace plan to raise the app limit.
2. Delete or archive unused apps to free quota before creating new ones.
3. Surface `FeatureService.get_features(...).apps` (`limit`/`size`) in the UI and disable the 'New App' button at the ceiling.
4. Confirm the features cache is fresh if the count looks wrong.

Example fix

// before
await createApp(payload)  // 403 at app cap
// after
const { apps } = await getFeatures()
if (apps.limit > 0 && apps.size >= apps.limit) {
  alert('App limit reached — upgrade or delete an app.')
} else {
  await createApp(payload)
}

from services.feature_service import FeatureService

_, tenant_id = current_account_with_tenant()
features = FeatureService.get_features(tenant_id, exclude_vector_space=True)
a = features.apps

def can_create_app() -> bool:
    return not (a.limit > 0 and a.size >= a.limit)

if not can_create_app():
    # surface upgrade / delete-app prompt instead of creating
    ...

def under_app_cap(limit: int, size: int) -> bool:
    return not (limit > 0 and size >= limit)

try:
    resp = client.post("/apps", ...)
except HTTPError as err:
    if err.response.status_code == 403 and "apps" in err.response.text:
        # app limit reached — upgrade or delete an app
        ...
    raise

When it happens

Trigger: Creating a new app on a tenant whose app count equals or exceeds the plan's app limit (limit > 0).

Common situations: Free/starter plan with a low app cap; user duplicating apps to template many workflows; bulk import pushing the count over the limit.
