| Purpose | Azurite is an open source Azure Storage API compatible server emulator for trying Azure Storage in a local environment. | LocalStack simulates cloud environments on customer infrastructure so developers and AI agents can validate cloud applications before deployment. |
| Telemetry | Azurite collects telemetry by default and provides an option to disable collection for an execution. | The open-source version may send anonymized usage information to a central server, alongside update and error-reporting communications. |

In their own words
Azurite
Azurite is a free, open-source server emulator for trying Azure Storage APIs on a local machine. Azurite V3 supports Blob and Queue storage, while Table storage is marked preview. Blob functionality includes containers, block and page blobs, service properties, and CRC-64/NVME transactional checksum checks for specified writes. Queue operations cover creating queues and putting, getting, peeking, updating, deleting, and clearing messages. Documented authentication includes Shared Key, account and service SAS, OAuth, and supported public access. It works with Azure Storage SDKs, Azure CLI, and Storage Explorer. Installation options are npm, Docker, a Visual Studio Code extension, or cloning and building the source. The npm route supports Windows, Linux, and macOS with supported Node.js LTS versions. Local hosts, ports, workspace, and optional in-memory persistence are configurable. Telemetry is enabled by default, with an execution-level disable option. It uses the MIT License.
LocalStack
LocalStack simulates cloud environments on customer infrastructure so developers and AI agents can validate applications before deployment. It currently emulates AWS and Snowflake, with AWS coverage described as 120+ services; an Azure public preview is coming soon. A typical workflow deploys application code and infrastructure-as-code resources into a local container, where teams can inspect failures and validate fixes before changing the endpoint to ship. LocalStack can run in GitHub Actions, GitLab CI, CircleCI, and Jenkins through a Docker image. The listed infrastructure-as-code tools include CDK, Terraform, and Pulumi. LocalStack is designed for development and testing, not production customer-facing applications. Hobby is free, offers 30+ emulated services and one personal sandbox, and is restricted to non-commercial use. AWS Base costs $39 a year, billed at $39 per license per month annually, or $45 per license per month billed monthly. LocalStack supports API, Linux, macOS, self-hosted, web, and Windows environments.
