What it does
A fully functional local AWS cloud stack. Develop and test your cloud & Serverless apps offline! Try our community version on Github, and check out the Pro edition with a large set of extended APIs and features!
LocalStack creates secure cloud development and testing sandbox environments so AI agents, software developers, and CI/CD pipelines can build, test, and validate applications before they touch the cloud.
LocalStack simulates cloud environments on your own infrastructure so software teams and AI agents can validate security, quality, and reliability faster and more safely than the cloud allows. LocalStack makes it easier for software teams and AI agents to fix security risks, bugs, and defects that they struggle to diagnose in the cloud. Using your existing application code and IaC resources, AI agents deploy to a local container that simulates your production app environment’s behavior. No access, cloud costs, or provisioning delays required. LocalStack surfaces the defects that will cause failures when you push to production so AI agents can validate reliability early in the development…from localstack.cloud

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
