Lambda Web Functions run full web apps on Lambda, no adapters.
On Thursday, AWS and LocalStack go live to show what's new and how to build and test them locally, with an end-to-end demo.

ALT Live webinar, Oct 22, 10am ET: Lambda Web Functions, deep dive with AWS. What's new, plus a live local demo with LocalStack. Register free.
New research: we asked 309 enterprise devs and eng managers how AI is changing cloud development.
65% write at least 2x the code.
Nearly 40% of AI-generated code never ships.
42% wait 10+ min for staging after every push.
Full report: tinyurl.com/ls-ai-report-x

AWS Lambda Web Functions launched yesterday, and you can already build and test them locally with LocalStack.
Full web apps and API backends on Lambda, with hot reload instead of a package-and-deploy loop.
Supported from day one in LocalStack for AWS 2026.10.0.
ALT AWS Lambda Web Functions, built and tested locally. Supported in LocalStack from day one.
Shared staging: where one team's test run quietly breaks another's.
ECI Research on LocalStack for Azure: a single-tenant sandbox per developer, no cloud credentials, and your existing Bicep or Terraform as-is.
What's your worst shared-staging story?
ALT Quote card: "…shared staging environments, where one team's test run can corrupt another team's state." Paul Nashawaty and Samantha Weston, ECI Research, on LocalStack for Azure, now in Public Preview.
Your AI agent can run your local cloud.
One command sets up the LocalStack MCP server for Claude Code, Cursor, VS Code, Codex and more:
npx -y @localstack/localstack-mcp-server init
Then just ask: "Start LocalStack and create an S3 bucket."

We're excited to officially launch lstk, the new CLI for working with LocalStack. lstk offers a better developer experience than the legacy CLI with more intuitive commands, no authentication friction, no python dependencies & more. Learn more here 👉 blog.localstack.cloud/introd…
Why test in the cloud when you can make the exit at LocalStack? 😂
Skip the deploy → wait → debug → repeat loop. Test your AWS workloads locally, break things freely, and ship when you’re actually ready.
Your cloud bill will understand. Probably. 🫡
You run kubectl apply. Kubernetes says configured. Then a pod appears. What happened in between?
Join Kiah Imani on Aug 26 at 16:00 CEST for What the YAML?! — a walkthrough of Kubernetes deployment at every stage, all on LocalStack.
