LocalStack

We're running a hands-on workshop with the AWS Connected Community. You'll build a coffee-ordering serverless web application and work through event-driven architecture patterns along the way. What we'll cover 👇 - AWS Lambda and Lambda Durable Functions - Amazon EventBridge for routing events between services - Developing and testing the full stack locally with LocalStack Register and join us tomorrow! https://lnkd.in/edsQs5mE #AWS #Serverless #EventDriven #LocalStack #Lambda #DurableFunctions

More AI-generated code means more code enterprises need to test safely. That is why I see the development environment as part of the AI governance stack. Agents need a bounded place to generate, execute, and revise code before accessing live cloud systems. LocalStack’s public beta for Microsoft Azure gives developers and agents a local environment to test against Azure APIs without live cloud credentials, provisioning delays, or cloud charges on every iteration. Local simulation still needs to be followed by validation in Azure. Its value is catching problems earlier and making experimentation faster, safer, and less expensive. I’m quoted in today’s announcement on why this matters for autonomous software development. The infrastructure for verifying AI-generated code deserves more attention. Congratulations to the LocalStack team on the Azure launch! #EnterpriseAI #AIStack #AgenticAI HyperFRAME Research Steven Dickens Rosa Hamilton Ron Westfall Don Gentile Stephen Sopko Fred McClimans Amber Rowland https://lnkd.in/eGbxAdse Follow me for analysis of the AI stack, enterprise software development, and what it takes to make AI work in production.

LocalStack for Azure is now in Public Preview. Run core Azure services locally, including Azure Kubernetes Service, Azure Functions, App Service, Container Apps, Cosmos DB, Storage, Service Bus, Key Vault, App Configuration, Virtual Networks, and Managed Identity. Deploy with your existing ARM and Bicep templates, Terraform modules, Pulumi programs, or Azure CLI scripts, then test your applications without waiting on a dev subscription or paying for every iteration. It's built for developer and platform teams, and for AI agents that need a safe place to deploy, break, and retry. Self-serve and free during the preview. https://lnkd.in/dQTqJi_B #LocalStackForAzure #LocalStack #Azure #CloudDevelopment #CloudTesting

AWS Amplify Gen 2 now runs on LocalStack. Learn how to deploy an Amplify Gen 2 backend to LocalStack, run the React frontend against local Cognito and AppSync endpoints, inspect the resources Amplify created, and iterate on the schema without an AWS account. 🔗 Tutorial: https://lnkd.in/dh2RSvd8 #AWS #Amplify #LocalStack #Serverless

Your coding agent can start LocalStack, deploy your infrastructure, and debug it, all from the chat. Here's the LocalStack MCP Server in under a minute: 1️⃣ Run one command: npx -y @localstack/localstack-mcp-server init 2️⃣ Pick your MCP clients. The wizard detects Claude Code, Cursor, VS Code, Codex, OpenCode, Amazon Q CLI and more, then writes the config for you. 3️⃣ Ask your agent: "Start LocalStack, then create an S3 bucket called mcp-demo and list my buckets." That's it. Claude Code calls the LocalStack MCP tools, starts the container, runs the AWS commands against your local cloud, and reports back. The MCP server is in public preview and needs a LocalStack Auth Token. Give it a spin and tell us what you'd want your agent to do next. 🔗 https://lnkd.in/essXgjjV #LocalStack #MCP #AWS #AIAgents #DeveloperTools

🚀 LocalStack for AWS 2026.09.0 is out! Our latest release brings major enhancements to our AWS cloud emulation. Key Highlights include: • S3 Files Support: Mount versioned S3 bucket data directly into Lambda, ECS, and Batch workloads using standard file system operations. • New Engine Defaults: The next-gen DynamoDB and Kinesis engines are now default for all users, bringing shard-aware pollers, concurrent processing, and checkpointing to EventBridge Pipes & Lambda ESMs. • Timestream Scheduled Queries: Full lifecycle support for scheduled queries, execution parameters, and SNS notifications. • Expanded Observability & IaC: CloudWatch Logs Insights query support in the v2 provider, expanded AppSync GraphQL/Events features, and new CloudFormation resource support. The easiest way to upgrade? Just run lstk to pull the latest image automatically.

Say goodbye to onboarding friction and cryptic startup errors when getting started with LocalStack. Setting up local cloud environments can sometimes get tripped up by an untrusted corporate proxy, insufficient RAM allocation, or hidden DNS misconfigurations, etc. LocalStack's new lstk CLI recently introduced the lstk doctor command to eliminate these headaches. Key benefits for engineering teams and developers: • Zero-Guesswork Onboarding: Diagnostics run in seconds before your first lstk start, surfacing issues instantly. • Actionable Self-Healing: Every check comes with concrete, copy-paste fixes (like required environment variables or config tweaks) rather than generic error codes. • Proactive Prevention: Validates network connectivity, container engine availability, memory, and TLS certificate chains concurrently. • Safe & Non-Intrusive: It only inspects your environment. It won't alter your system or require a running emulator to work. Whether you're setting up local AWS development on a new machine or onboarding new team members, lstk doctor helps get you up and running faster without frustration.

Calling our Japan community! Tokyo local dev enthusiasts, we're coming your way. Join our CTO Waldemar Hummer on October 8 at 6:30 PM for an evening of talk and networking at XLSoft. It's free, so reserve your spot today: https://lnkd.in/e4TfeuKt

We gave Claude Code the LocalStack MCP server and a CSV export of SaaS billing data. We asked it to build a quarterly Revenue-by-Plan report on our Snowflake emulator. Here's what it did: 1. Loaded the data 2. Found & fixed two bugs 3. Proved the result All of this happened without ever touching the real Snowflake cloud. Read the details: https://lnkd.in/eUN4ue3m

In case you missed the announcement last week: AWS Lambda Durable Functions are now officially supported in LocalStack! This will help you eliminate slow deploy-and-test cycles. With LocalStack, you can now run and debug your entire durable workflow locally from start to finish. In this step-by-step tutorial, Harsh Mishra walks through how to: 📦 Deploy a durable order-processing workflow with AWS CDK 🔄 Test step retries and exponential backoffs against a flaky API ⏸️ Pause executions and resume them asynchronously using callbacks 💥 Simulate crash recovery and container restarts mid-execution to verify persistence Check out the full walkthrough on the LocalStack blog: https://lnkd.in/dPUR4SHc #AWS #Serverless #Lambda #LocalStack #CloudDevelopment #DevOps
