Build and test a real-time payment fraud detection pipeline locally with LocalStack for Azure. Stream payments through Event Hubs using AMQP, Kafka, and HTTPS, process them with Azure Functions, and explore checkpoints, Event Hubs Capture, and Blob Storage before deploying to Azure.
Stop writing bigger and bigger prompts for your AI coding agent. Learn how to build an AI-native AWS development environment using Cursor Rules, agent skills and plugins, the AWS MCP Server, and LocalStack so your agent has what it needs to build, test, and debug AWS applications locally before touching a real cloud account.
We’re launching the LocalStack Champions program to recognize developers who build, share, and support others in the community. If you’re creating content, helping in Slack, or building with LocalStack, this is your opportunity to get recognized.
Learn how to run AWS Lambda Web Functions locally with LocalStack by deploying an Express URL shortener backed by DynamoDB and S3 with the AWS CLI, calling its endpoint, and reading its logs and metrics.
309 developers and managers on AI in software development: 79% give AI agents cloud access, 97% worry, and nearly 40% of AI code never ships.
AWS Lambda Web Functions let you run full web apps and API backends on Lambda, with no adapters or custom configuration. LocalStack supports them from day one, so you can build and test those apps locally, alongside the rest of your application, before deploying to AWS.
Run core Azure services on your own machine. Build and test Azure applications locally, self-serve and free during the preview.
Learn how to deploy an AWS Amplify Gen 2 backend to LocalStack with ampx sandbox, run the React frontend against the local Cognito and AppSync endpoints, inspect the resources Amplify created, and iterate on the schema without an AWS account.
We gave Claude Code the LocalStack MCP server and a CSV export of SaaS billing data, then asked it to build a quarterly Revenue-by-Plan report on our Snowflake emulator. It loaded the data, found & fixed two bugs, and proved the result, without touching the real Snowflake cloud.
79% of developers say AI agents have access to cloud environments for development, testing, or staging, and 97% have concerns. That makes agentic AI security a dev and test problem first.
Proxies, TLS inspection, and locked-down laptops can stall a first LocalStack run. lstk doctor runs 11 checks in one pass, finds the root cause, and gives you the exact fix.

Learn about LocalStack's acquisition of WonderTwin AI and how application emulation enables agentic full-stack emulation for AI-native software development.
Real horror stories of AI agents deleting production and running up surprise cloud bills, what they have in common, and how to give agents a sandbox instead of the keys to prod.
AT Protocol is more than just Bluesky. This post explains what ATproto is, why it matters for event-driven apps, and how to build a reusable AWS pipeline for consuming it — including testing the full stack on LocalStack before touching a real account.
Stop writing bigger and bigger prompts for your AI coding agent. Learn how to build an AI-native AWS development environment using Cursor Rules, agent skills and plugins, the AWS MCP Server, and LocalStack so your agent has what it needs to build, test, and debug AWS applications locally before touching a real cloud account.
AI agents are getting capable enough to provision infrastructure and execute code with real consequences. Here's a taxonomy of AI sandboxes and where LocalStack fits as the missing cloud infrastructure layer.
You've run kubectl apply a thousand times. But what actually happens? This post breaks down the full Kubernetes deployment lifecycle, every component, every handoff, and shows you how to watch it happen live with LocalStack.
App Inspector is LocalStack's built-in observability layer that shows you every AWS API call, IAM permission evaluation, and full request/response payload your app makes locally, before it ever hits a real AWS account.
Kiro Crew runs AI agents on a schedule. Build a Crew app that deploys an AWS app to LocalStack, tests it, and has the agent diagnose an IAM failure.
We pointed several AI agents to build an AWS app in parallel, using the LocalStack MCP Server. Each agent built a different part of the app in its own Git worktree and deployed to a separate Ephemeral Instance, avoiding conflicts and making it easier for agents to work independently.
