Often searched for as a local multi-cloud simulator or a LocalStack alternative — Vyomi goes further: a real digital twin on real backends across all three clouds, not single-cloud mocks.

LocalStack mocks AWS; Moto, Azurite, and the GCP emulators each cover a single cloud. Vyomi runs all three major clouds on real backends (Postgres, MySQL, MinIO/S3, DynamoDB, Vault, NATS, Azurite, the Firestore emulator) with native multi-cloud NoSQL —…
