🚨 Our next meetup is 24 hrs away! 🚨 Join Shelton & Cristian from our team to see how App Inspector opens up the black box of AWS development with a real-time view of every service interaction inside your local cloud. RSVP 👉 www.meetup.com/localstack-c... #LocalStack #AppInspector

Debugging service to service communication in AWS can be painful. There might be IAM misconfigurations, payload mismatches, broken event triggers, routing issues, or all of the above. App Inspector alleviates that pain by visualizing the entire flow of your app. blog.localstack.cloud/introducing-...

Have you tried our new CLI yet? lstk is in early release. It's a single binary (no more messing with Python) & makes setup easy (no more manually setting auth tokens). Plus, it has a TUI to make it easier to read or decipher the LocalStack logs. Details here: docs.localstack.cloud/aws/tooling/...

The latest LocalStack for AWS release is officially here. This update brings major enhancements, including AWS Batch Multi-Node Parallel jobs, self-managed EC2 nodes on emulated EKS clusters, expanded AWS Replicator coverage. Read the announcement: blog.localstack.cloud/localstack-f...

Debugging async AWS service chains locally is painful when you can't see what's happening. App Inspector, a new feature built into LocalStack, records every AWS API call your app makes in real time. See how 👉

"It just works" isn't a satisfying answer when it doesn't. This post maps the full lifecycle between `kubectl apply` & a running pod – every component, every handoff. So when a deploy breaks at 2am, you know which step failed & which component to blame blog.localstack.cloud/7-steps-from-yaml-to-pod/

Solving the "Static Environment" Bottleneck 😅 In a traditional cloud-native SDLC, pre-production environments are often "static." They persist over time, accumulating configuration drift and state pollution that makes debugging non-deterministic. docs.localstack.cloud/aws/capabili...
