Mock Cloud Resource ID Generator

Used by developers, writers, and creators worldwide.

A mock cloud resource ID generator creates realistic AWS ARNs, GCP resource paths, and Azure resource IDs for testing, documentation, and tool development. Cloud identifiers follow strict provider-specific conventions — account IDs, project slugs, subscription GUIDs — and hand-crafting them wastes time. This tool generates correctly formatted fake identifiers in one click. Use them to populate a cost dashboard with sample data, test an IAM policy parser against realistic ARNs, or fill Terraform module docs with plausible resource references. Pick a single provider or generate IDs across all three clouds at once. No real credentials are needed, and nothing gets logged.

  1. Choose your options above
  2. Click Generate

Detailed instructions

  1. Choose a cloud provider — AWS, GCP, or Azure — or select All for a mixed set.
  2. Set how many resource identifiers you need.
  3. Click Generate to produce realistically-formatted fake resource IDs.
  4. Copy the IDs into your test fixtures, mock responses, or documentation.

Use Cases

  • •Populating a cloud cost dashboard UI with realistic-looking AWS ARN sample data
  • •Testing an IAM policy parser against correctly formatted multi-provider resource identifiers
  • •Filling Terraform module README examples with plausible GCP resource path references
  • •Seeding a mock Azure inventory database for Cypress integration tests
  • •Building multi-cloud infrastructure tutorials without exposing real subscription IDs

Tips

  • →Match the provider to the SDK or API your code targets so the ID format is realistic.
  • →Use these to test parsing and validation, never to reference a real cloud resource.
  • →Generate a varied batch to confirm your code handles different providers' ID shapes.
  • →Pair with a mock API response generator to build complete, believable cloud fixtures.
  • →Keep generated IDs out of production config — they point at nothing real.

FAQ

what does a valid AWS ARN actually look like

An ARN follows the pattern arn:partition:service:region:account-id:resource — for example, arn:aws:s3:::my-bucket. The generator produces ARNs matching this structure with randomised account IDs and regions, so they pass format validation without pointing to a real account.

can these fake resource IDs break anything if accidentally used in real cloud configs

No — the account IDs, project slugs, and subscription GUIDs are randomly generated and won't match any real cloud account. That said, always double-check before committing IaC files to production pipelines.

what's the difference between AWS ARNs GCP resource paths and Azure resource IDs

AWS ARNs use a colon-separated flat string starting with arn:; GCP uses a hierarchical slash-separated path like projects/{project}/locations/{region}/...; Azure uses a long slash-separated path rooted at /subscriptions/{guid}. Each format is provider-specific and this generator handles all three correctly.
