Hi, I am from Azure Cosmos DB Engineering Team. For development (before going into production) with Azure Cosmos DB, we suggest a number of options (also documented here: https://docs.microsoft.com/en-us/azure/cosmos-db/optimize-dev-test https://docs.microsoft.com/en-us/azure/cosmos-db/optimize-de...): [1] Cosmos DB emulator (Cosmos DB Local version) - https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator https://docs.microsoft.com/en-us/azure/cosmos-db/local-emula.... The Azure Cosmos DB Emulator provides a local environment that emulates the Azure Cosmos DB service for development purposes. Using the Azure Cosmos DB Emulator, you can develop and test your application locally, without creating an Azure subscription or incurring any costs. When you're satisfied with how your application is working in the Azure Cosmos DB Emulator, you can switch to using an Azure Cosmos DB account in the cloud. Support for Cosmos DB emulator on Linux is coming. [2] We provide Try Cosmos DB for free experience - https://azure.microsoft.com/try/cosmosdb/ https://azure.microsoft.com/try/cosmosdb/. There is Try Azure Cosmos DB for free experience which gives you a time-limited full-service experience with Azure Cosmos DB. It is designed for trying out Cosmos DB, doing a tutorial, a demo, doing a quick start, a lab without requiring an Azure account or a credit card. [3] We provide a free tier (Cosmos DB is a part of free account) - https://azure.microsoft.com/free https://azure.microsoft.com/free. In Azure, we support a free tier with 12 month access to all popular services in Azure. As a part of free tier specifically for Cosmos DB you get 5GB in storage and 400RUs. Thanks so much!
