What it is: a local-first desktop tool to inspect, test and mock REST, GraphQL,
gRPC and SOAP APIs, generate test code, author contracts, and run local mocks.
Why it's a good catalog fit:
- Windows installer is code-signed (Azure Trusted Signing) and RFC-3161
timestamped, so signatures stay valid after the short-lived cert expires.
- Frequent releases on a stable, public feed, easy to track.
