Run AWS locally. LocalEmu is a free, open-source AWS emulator: one pip install, one command. Same CLI, same SDK, same Terraform. No paid tier, no account, no telemetry, with persistent state included. Because local development deserves local infrastructure. Real AWS is built for production. Here is what happens when teams use it for development and testing. Cloud-native dev loops can stretch from seconds-on-localhost to multiple minutes per code-build-test cycle. Daily iteration counts drop accordingly. Dev/test AWS costs commonly run from hundreds to thousands of dollars per month. Forgotten or orphaned resources regularly produce four- and five-figure surprise bills per team. Millions of…from localemu.cloud

Hiraeth – AWS EmulatorApr 2026 · github.com · ▲40With the recent changes around Localstack pricing/licensing I've been hunting for alternatives. I decided that it might be a fun experiment to try rolling my own. SQS is a service I use heavily so I chose that as the first service to implement. I have more services planned and in development. A few things I think are cool: 4MB Docker Image Size Instant Startup AWS Sigv4 Authentication A little admin UI that can be helpful for development/troubleshooting Most of the SQS API implemented, the rest will soon follow :)

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…

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
