We gave Claude Code the LocalStack MCP server & a CSV export of SaaS billing data. We asked it to build a quarterly Revenue-by-Plan report. It loaded the data, found/fixed 2 bugs & proved the result, without touching the real Snowflake cloud. blog.localstack.cloud/test-s…

ICYMI: LocalStack now supports local testing for AWS Lambda Durable Functions! Test your entire durable workflow locally: ✅ Step retries & backoffs ✅ Callback tokens ✅ Container restarts mid-execution Full tutorial below 👇 blog.localstack.cloud/testin…

Learn how to build and test Lambda Durable Functions on LocalStack by deploying an order-processing workflow, watching checkpoints retry a flaky gateway, surviving a mid-execution restart, and resuming the workflow with a callback. Read our tutorial 👇 blog.localstack.cloud/testin…

We acquired WonderTwin AI. LocalStack has always been about running AWS on your laptop. Now the same idea covers SaaS APIs too. Build the Slack/Stripe/whatever integration locally, test it, then ship. No live API keys, no staging box, no surprise bill. devops.com/localstack-acquir…

We asked Claude Code to run a chaos game day against a serverless data pipeline on LocalStack: define a steady state, inject faults, diagnose the failures, fix the pipeline, and prove the fix by replaying the same faults. Read more on how it worked out: blog.localstack.cloud/ask-yo…

What an incredible time we had at KCDC 2026! 🍻 Huge thank you to everyone who stopped by the LocalStack booth to chat about local cloud development, grabbed some swag, and tuned in for Kiah’s sessions on Chaos Engineering and AWS Kubernetes internals.

Testing an AWS Fargate workload shouldn’t mean waiting on a cloud deployment every time you change your code. 🐳 Learn how to run and test a full SQS → Fargate → DynamoDB workflow locally with @localstack. blog.localstack.cloud/how-to…

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. 🔗 localstack.cloud/events/what…

AWS ships a fleet of MCP servers that let agents write IaC, validate it, and invoke Lambda functions. Point them at LocalStack instead of AWS, and an agent can build, harden, deploy & test the app locally. Here is how we wired them and what happened. blog.localstack.cloud/use-aw…

Stop deploying Terraform to a staging account just to test it. Ammar Ekbote wrote a guide on wiring Terraform to LocalStack, covering provider configuration, endpoint overrides, and a fully working SQS queue. ⚡ No bills. No real resources. No latency. dzone.com/articles/localstac…
