What LocalCloud really offers

Comparison notes. Test permissions, HMAC credentials, object moves and notification recovery. Compared with fake-gcs-server. Permission checks require an HTTP authorization callback. HMAC verification covers supported XML routes; moves stay within one bucket. Features that neither LocalCloud GCS nor fake-gcs-server supports are not listed. Counts describe documented rows and can overlap.

Comparison notes. Test missing-index failures, query Explain and optimistic transaction conflicts. Compared with Google Firestore emulator · Java 1.22.0. Extended-profile features need their documented configuration. Persistence and Admin APIs require a configured engine, not just a CLI profile switch. Features that neither LocalCloud Firestore nor Google Firestore emulator supports are not listed. Counts describe documented rows and can overlap.

Comparison notes. Keep persistent data and test backups, restricted views, change streams and SQL. Compared with Google Cloud Bigtable emulator · client library v1.58.0. Change streams use one local partition. IAM policies manage configuration without enforcing identity. Google emulator results come from its open-source implementation, not from a Cloud SDK bundle. Features that neither LocalCloud Bigtable nor Google Cloud Bigtable emulator supports are not listed. Counts describe documented rows and can overlap.

Comparison notes. Persist databases, test backup recovery and database roles, and execute graph algorithms. Compared with Google Spanner emulator v1.5.58. This comparison uses v1.5.58. Persistence and backups require --data_dir. Database roles enforce privileges; IAM policies do not. Features that neither LocalCloud Spanner nor Google Spanner emulator supports are not listed. Counts describe documented rows and can overlap.

Comparison notes. Run ML, external tables, federation, policies, snapshots and clones alongside SQL. Compared with goccy BigQuery emulator. Generative ML requires a configured provider. Competitor results come from its documentation, source or backend declarations, not new test runs, and unassessed behavior never counts as a missing feature. Features that neither LocalCloud BigQuery nor goccy BigQuery emulator supports are not listed. Counts describe documented rows and can overlap.
