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.
The LocalStack for Open Source program offers free licenses of LocalStack for AWS and LocalStack for Snowflake to eligible community open source projects to help speed up their development and lower their costs.
Learn how to test Service Control Policies with LocalStack by building a local AWS organization, attaching guardrails to a sandbox account, reading denial messages that name the exact policy, and simulating SCP conditions before they reach production.
Learn how to test Amazon S3 replication with LocalStack by configuring a cross-Region replication rule, catching an under-privileged replication role with IAM enforcement before it ships, and validating the whole flow, end-to-end on our local machine.
Learn how to run LocalStack on Jenkins with Docker-in-Docker when Docker socket mounting is unavailable, using an isolated DinD daemon for CI integration tests.
Learn how to orchestrate dbt pipelines on the Snowflake emulator with Apache Airflow and Astronomer Cosmos using LocalStack's MWAA emulator to run seeds, models, and validation queries locally.
One theme kept coming up in nearly every one of the hundreds of conversations we had at AWS Summit NYC: AI agents are already writing infrastructure code, and engineering teams are still figuring out how to test it safely.
Learn how to run Glue ETL jobs that connect to Snowflake entirely on your local machine using LocalStack. You'll set up the infrastructure with Terraform, write a PySpark Glue job that reads from a local Snowflake emulator via JDBC, and verify it all through CloudWatch Logs.

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.
New to LocalStack but familiar with AWS? Learn what LocalStack is, why it speeds up your development workflow, and how to get your first local AWS environment running in minutes.
Learn how to use the Keycloak extension to add OAuth2/OIDC authentication to your AWS apps. Walk through a sample app with API Gateway, Lambda, and DynamoDB that uses Keycloak JWTs for role-based access control, all running locally without cloud dependencies.
Learn how to test AWS Fargate container workloads locally with LocalStack by deploying a CDK stack that runs a message-driven Go app on ECS Fargate, processing SQS messages into DynamoDB, and validating the full flow with integration tests.
AWS ships a fleet of official MCP servers that let agents write IaC, validate it, and invoke Lambda functions. Point them at LocalStack instead of real AWS, and an agent can build, harden, deploy, and test the cloud app locally. Here is how we wired them up and what happened.
We gave Claude Code the LocalStack MCP server and a production bug report about a broken dead-letter queue, then watched it deploy, reproduce the failure from App Inspector traces, fix the pipeline, and prove the fix, without touching an AWS account.
Learn how to test Service Control Policies with LocalStack by building a local AWS organization, attaching guardrails to a sandbox account, reading denial messages that name the exact policy, and simulating SCP conditions before they reach production.

We launched a dedicated entry point that lets your AI agent discover, install, and start using LocalStack without you having to explain anything. Here's what's in it and why we built it.
App Inspector gives engineering teams full transparency within their local development environment by continuously monitoring your emulated AWS environment to surface hidden issues, helping your team understand what is happening, where, and why.
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.
