LocalStack

AWS just launched AWS Emulator: local AWS services for developers and AI agents.

In 2017, people asked us why anyone would run the cloud locally. Now AWS is building it too.

Congrats to the @awscloud team 👏 Here's what it means if you use LocalStack 🧵

Meet the heroes of Stack Escape, our 15-min game at #AWSreInvent where you debug a broken AWS app.

Hero #1: Proxyx, who guards the gate (API Gateway). An AccessDenied error has Proxyx trapped. Fix it and Proxyx walks free.

Play at Booth #1304, Nov 30-Dec 3 👇

The Local Cloud Sandbox for Developers & AI Agents is heading to re:Invent.

Booth #1304, Nov 30-Dec 3. Play Stack Escape (debug a broken AWS app in 15 min) and watch agents build, test and validate locally 👇

#AWSreInvent

$ curl -I localhost:2026
HTTP/1.1 200 OK

The only AWS re:Invent afterparty for the local cloud.

Wed Dec 2, 6-9 PM PT, Las Vegas. Food, drinks, giveaways and Stack Escape, our 15-min AWS debugging game. Open to all 👇

The @AWSAmplify Gen 2 sandbox redeploys on every save, and each one waits on a real CloudFormation stack in AWS.

We ran the whole loop on LocalStack instead:

- ampx sandbox, locally
- React app on local Cognito + AppSync
- live schema edits with hot swap

No AWS account 👇
