# LocalStack for Azure is now in Public Preview > Source: > Published: 2026-10-08 08:29:24+00:00 Building on Azure usually means testing on Azure. Every change to a function, a container app, or a Cosmos DB integration follows the same loop: deploy to a dev environment in Azure, wait, check the logs, fix, redeploy. Add access requests, permission approvals, and shared environments that break when two teams test at once, and a one-line fix can cost an afternoon. Today, LocalStack for Azure is open to everyone in Public Preview. It’s a local Azure sandbox where developers and AI agents can build, test, and validate Azure applications before anything touches live Azure resources. Access is self-serve and free for the duration of the preview. ### **Test Azure changes without waiting on Azure** **Get feedback locally.** Run supported Azure services on your machine and see the result of a change without waiting on remote provisioning or deployments. **Bring your existing IaC.** Deploy your ARM templates, Bicep templates, and Terraform modules locally and validate infrastructure changes before they reach a live subscription. No rewrites needed. **Give every developer an isolated sandbox.** No shared dev environment, no queue, no tests colliding with another team’s changes. **Keep dev/test off your Azure bill.** Local runs don’t consume Azure resources, so you can test as often as you need. That cuts the non-production spend that’s hard to track and harder to control. **Give AI agents a safe place to iterate.** Agents can deploy, break, and retry in a local sandbox. They don’t need live credentials, each attempt costs nothing in cloud spend, and they can’t make unintended changes to real Azure resources. ### **What’s in the Public Preview** This release focuses on the emulator core: high-fidelity service behavior, reliability, and compatibility with the workflows enterprise teams already run. - **Containers:** Azure Kubernetes Service (AKS), Azure Container Apps - **Serverless and data:** Azure Functions, Web Apps, Storage Account, Cosmos DB - **Security and networking:** Key Vault, Managed Identity, Private Endpoint (mocked where applicable) - **Infrastructure as Code:** ARM templates, Bicep templates, and Terraform modules We focus on the services typical enterprise dev/test workflows depend on, rather than claiming parity with all of Azure. The [supported services page](https://docs.localstack.cloud/azure/services/) lists known limitations and workarounds for each one, so you can check coverage against your architecture before you start. ### **What Public Preview means** - **It’s free.** There’s no cost during the preview. Pricing will be announced at GA, currently expected in early 2027. - **It’s emulator first.** Developer experience features such as App Inspector, snapshots, and chaos/resiliency APIs aren’t included at preview launch. Some may arrive during the preview, and others will follow GA. - **There’s a clear path to GA.** Preview access ends at GA. We’ll give you at least 30 days’ notice and publish transition steps ahead of time. - **It’s built for dev and test.** LocalStack for Azure speeds up the work before you deploy to Azure. It doesn’t replace Azure. ### **Get started in under five minutes** 1. Sign up for the Azure preview plan on the [LocalStack for Azure pricing page](https://www.localstack.cloud/pricing?tab=azure) . Already on LocalStack for AWS? Sign in with your existing account and add the Azure preview plan. 2. Follow the [Getting Started guide](https://docs.localstack.cloud/azure/getting-started/) to start the emulator and run your first workload. ### **Help shape what ships at GA** Public Preview is where we validate service behavior in real workflows, so your feedback directly shapes what ships next.
