You've been there: Lambda triggers, SQS messages fly, Step Functions execute, and somewhere in the middle, something breaks. You have no idea what triggered what, what payload was passed, or where it all went wrong.
That's the black box problem of AWS development.
Once your architecture grows beyond a single service, visibility disappears fast. You're left stitching together scattered logs and redeploying just to see what's going on.
App Inspector is LocalStack's built-in observability layer that opens up that black box. It gives you a real-time, unified view of every service interaction happening inside your local cloud: what triggered what, with what payload, in what order.
In this talk, we'll walk through what App Inspector is, how it fits into your LocalStack workflow, and how to use it to catch bugs locally before they ever reach staging or production.

LocalStack is ephemeral, so when you stop and restart it, all data is lost. You can use certain features to save the state & load it back when you restart LocalStack. This includes saving the local state for S3 buckets, DynamoDB tables, RDS databases and more. In this video, we explore three mechanisms that allow you to save state in LocalStack: persistence, state export and import, and Cloud Pods.

In this video, you'll learn how to set up and integrate LocalStack's Snowflake Emulator to develop and test your Snowflake data apps in your local environment or CI pipelines. Whether you're using Snowpark, various client libraries, or building interactive data apps with frameworks like Streamlit, this emulator simplifies your developer experience. We'll walk you through step-by-step instructions on installing the Snowflake emulator with the LocalStack CLI & Docker, configuring and integrating the emulator with popular SQL clients, such as DBeaver, and running SQL queries locally to replicate a full Snowflake environment without cloud dependencies. ⚡ Get early access! The Snowflake Emulator is currently in public preview—reach out to us for access and start building today!

Real cloud developers aren’t pushing straight to AWS. They’re building and testing everything locally before a single deploy goes live. This episode breaks down the modern cloud dev workflow and how tools like LocalStack make it possible to move fast without burning money (or trust). Learn how local-first dev culture is changing the cloud game.
