Azure Cosmos Emulator

Azure Cosmos Emulator is a Windows application that provides a local environment emulating the Azure Cosmos DB service. It is intended for developers who need to build and test applications that use Azure Cosmos DB. By working locally, developers can examine application behavior without first creating an Azure subscription.

The emulator supports development and testing before an application is connected to an Azure Cosmos account in the cloud. This makes it suitable for checking an application during local development. It also allows developers to work without incurring Azure service costs during that local process. Once the application is working as expected in the emulator, development can move to an Azure Cosmos account in the cloud.

The software is available under a free license. Its main role is to provide a local counterpart to the Azure Cosmos DB service, rather than to serve as a separate cloud account. The product therefore fits the developer-tools category for Windows users working with Azure Cosmos DB applications.

MirrorNest does not mirror the installer or host a separate copy of the software. Instead, it links directly to the official release, giving readers a catalog entry that points to the original distribution source.
