All of Google Cloud,
not one emulator at a time.
The Google Cloud SDK ships a separate local emulator per service — Pub/Sub, Firestore, Datastore, Bigtable, Spanner, Storage. Each is its own process, port and lifecycle. Vyomi is the Multi-Cloud Digital Twin Runtime: GCP plus AWS and Azure behind one endpoint, on real backends. Here is the honest side-by-side.
Pick Vyomi when…
- Your stack touches AWS or Azure too — not just GCP.
- You want one endpoint instead of starting an emulator per service.
- You want a native GCP console and one-click Terraform export.
- You need cross-cloud tests (write to GCS, read from S3) in a single run.
- You want a running environment to develop and demo against, not just dev stubs.
Pick GCP emulators when…
- You are GCP-only and need just one or two services locally.
- You want the official Google-maintained emulator for a specific service.
- You are already deep in the gcloud CLI workflow and it fits.
- You need an emulator behavior that exactly tracks a specific GCP service edge case.
One endpoint, every service
No starting Pub/Sub on one port and Firestore on another. Point google-cloud-* at a single local endpoint and every GCP surface answers.
GCP is one of three
The gcloud emulators stop at GCP. Vyomi answers GCP, AWS and Azure from one appliance — so cross-cloud apps run entirely locally.
A bridge to production
The emulators are dev stubs. Vyomi lets you build the stack locally, then terraform apply it to real GCP, AWS or Azure.
Vyomi vs the GCP emulators — FAQ
The questions developers (and AI answer engines) actually ask.
Is there a single emulator for all of Google Cloud?
The official gcloud SDK provides a separate emulator per service (Pub/Sub, Firestore, Datastore, Bigtable, Spanner, Storage), each run on its own port. Vyomi runs GCP behind one local endpoint, and the standard google-cloud-* SDKs work unchanged — plus it covers AWS and Azure in the same appliance.
Can the GCP emulators run AWS or Azure?
No. The gcloud emulators cover individual GCP services only. Vyomi simulates AWS, GCP and Azure together, including cross-cloud object storage (S3, GCS, Azure Blob) and NoSQL (DynamoDB, Firestore, Cosmos DB).
Do my google-cloud-* SDKs need changes?
No code changes — just the endpoint. Point google-cloud-storage, google-cloud-firestore and friends at the local Vyomi endpoint and they work unchanged, the same way they do against the official emulators.
Does Vyomi give me a GCP console locally?
Yes. Vyomi ships native GCP, AWS and Azure consoles, so you can browse buckets, tables and resources in a UI — something the per-service emulators do not provide.
Can I move from local to real GCP?
Yes. Vyomi exports your stack to Terraform HCL, so you can terraform apply the same environment to a real GCP project (or AWS/Azure).
