Azure Cosmos DB Emulator
Azure Cosmos DB Emulator has no write-up on Specifiction yet; its figures are above.
Traffic Parrot
Traffic Parrot simulates APIs, services, and other systems so teams can test applications and microservices separately from the systems they depend on. It records and replays HTTP(S), gRPC, JMS, IBM MQ, Thrift, and file-transfer traffic. Scripting and templates produce dynamic responses, while stateful simulation, fault injection, database virtualization, and messaging virtualization cover different test scenarios. APIs plus Maven and Gradle plugins support automation, and an MCP server lets AI assistants discover and call its tools with optional bearer-token authentication. It can run in Docker, Kubernetes, OpenShift, AWS, Azure, Google Cloud, CI/CD pipelines, laptops, or virtual machines. Java 17 or later is required. Windows, Linux, macOS, web, API, and self-hosted use are listed. Pricing is on request; Enterprise depends on licence count and selected features. A 14-day trial requires a business email. Shared-environment user management is unavailable.
