Join our January meetup to learn how to build a unified, local testing environment that handles both AWS services and external APIs. 💪🏿 Stop wrestling with cloud latency and complex dependencies. You deserve better! www.meetup.com/localstack-c...

Multi-runtime testing is harder than it looks. Supporting multiple AWS Lambda runtimes isn’t just about adding a new version flag. Each runtime has differences in: · dependency resolution · build tooling & packaging · test isolation & execution order docs.localstack.cloud/aws/services...

.NET 10 support just landed in LocalStack 💪🏿 AWS recently released the new .NET 10 Lambda runtime, and we’ve already added support for it in LocalStack. 👉 PR: github.com/localstack/l...

LocalStack for Snowflake 1.6 is now available ❄️ It improves Iceberg integration for AWS S3 Tables and Polaris vended credentials, introduces new SQL functions, and delivers targeted parity updates. blog.localstack.cloud/localstack-f...

If you’re using Terraform and GitHub Actions, this one’s for you 👀 Learn how to automate Terraform testing locally with LocalStack so your CI runs faster without touching real cloud resources. 📖 🔗https://blog.localstack.cloud/automate-terraform-testing-localstack-github-actions/

Choose peace. Choose local.

We shared an update on what’s next for LocalStack 👀 Unified AWS image, changes coming in March 2026, and clarity on what remains free for the community. If LocalStack is part of your workflow, check it out 👇🏾

What if your AI coding assistant could not only write infrastructure code, but also deploy it, test it, and fix issues automatically — all on your local machine? That's exactly what the LocalStack MCP Server makes possible. Learn more about it here 👉 youtu.be/9DLSr7fxNag

You mean we should break things...on purpose?! Yes! Intentionally adding errors & latency into your app with chaos engineering helps ensure it is resilient when problems occur. Even better, as Kiah Imani shows, you can do this testing locally without risking production. youtu.be/nSEfnAgBjh0

LocalStack for Snowflake 1.5 introduces new SQL functions, enhanced support for Iceberg tables with CTAS, and parity improvements for window functions, large timestamps, & stage file operations for better local Snowflake development. Check it out here 👉 blog.localstack.cloud/localstack-f...

AWS Fault Injection Service (FIS) provides an API for injecting faults into your application to test resiliency. LocalStack enables creating FIS experiments & test them locally. In this post, Harsh Mishra shows how this works by injecting EC2 faults into an app. blog.localstack.cloud/testing-aws-...

There are 3 options for testing cloud applications: real cloud services, mocks or LocalStack for emulation. In this presentation, Fernando Teixeira shows why emulation offers the benefits of realistic tests that mocks cannot without the escalating costs of real cloud. www.youtube.com/watch?v=paSJ...

We're still feeling energized by last week's Re:Invent with one highlight being our CTO and co-founder Waldemar Hummer's lightning talk. If you missed it, it's already up on YouTube. Catch the replay here: www.youtube.com/watch?v=z0G0...

What if your AWS serverless bugs were autonomously found, fixed and tested while you slept, allowing you to wake up to validated PRs in the morning rather than bug reports and tickets? That's the promise of combining LogicStar's automated AI tooling with LocalStack.

Join our session to explore how AI agents are enabling systems that can autonomously detect, diagnose, and fix bugs. Boris Paskalev will show how AI agents can detect prod bugs, reproduce them, and generate validated PR with fixes, thereby removing bottlenecks from the debugging cycle.

Local Lambda testing hits different 😭🔥
