Can it do what I need?
The features that decide whether an emulator fits your project, against every target, from the latest run. These are cross-cutting capabilities: a feature like Global Secondary Indexes is exercised across several operations, so the operation matrix can't show it as a single line. This can.
The columns split in two: DynamoDB's own surface, and features that reach beyond DynamoDB into other AWS services - S3 for export and import, Kinesis for streaming, IAM for resource policies, CloudWatch for Contributor Insights, plus backups and PITR and the account-level APIs. A DynamoDB-only emulator won't implement these; one that also emulates the surrounding services - LocalStack, say - generally can, and some implement backups or PITR directly.
- Supported
- every test for the feature passes.
- Partial
- the feature works, with gaps: some tests pass, some fail or skip. Usable, but check the edges.
- Failing
- the feature is implemented but passes nothing at all.
- Not supported
- the target doesn't implement the feature.
Hover a cell for the exact pass, fail and skip counts. For the full per-operation breakdown, see the support matrix.

Know an emulator we're missing?
If there's a DynamoDB emulator or compatible adapter that isn't tracked here, suggest it. Anything that speaks the DynamoDB HTTP API can be run through the same suite and scored against live AWS.
