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.
Starting with the March 2026 release, all LocalStack products follow a new YYYY.MM.patch version format. Here's what's changing and what it means for you.
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 run the official AWS CDK integration testing framework (integ-runner and integ-tests-alpha) against LocalStack for AWS, using a friend request microservice built using AWS services with Lambda, API Gateway, DynamoDB, and SQS.
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.
Learn how to build a custom AWS Lambda extension using the Extensions API. This tutorial walks through creating an audit-log extension that tracks every invocation and writes a report to S3, deployed and tested locally on LocalStack.
How to shift cost policy left into your local development workflow using CloudBurn and LocalStack, with a pre-commit hook that tells you whether your IaC changes made things better or worse before you commit.
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.
Let's look at 3 things you may not be aware of about LocalStack for AWS including that it's free for many use cases, has no CI limits and is validated against thousands of tests to ensure API accuracy.
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.
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.
