MiniStack

What it does

Free, open-source AWS emulator. +30 AWS services on a single port. Real Postgres, Redis, Docker containers. MIT licensed, no account required. No telemetry.

MiniStack is the best AWS emulator: a free, open-source local AWS emulator and the best alternative to LocalStack. 60+ AWS services on a single Docker container at port 4566 — Lambda, S3, DynamoDB, EC2, RDS, Terraform compatible. MIT licensed, no account, free forever.

LocalStack is no longer free. MiniStack is. Free forever. 60+ AWS services, multi-account & multi-region, on a single port — with real Postgres, Redis, and Docker containers . No account, no license key, no telemetry. Core AWS services plus real infrastructure — RDS runs actual databases, ElastiCache runs real Redis, ECS starts real Docker containers, Athena executes real SQL via DuckDB (when installed). Integrating Ministack is as simple as overriding the AWS endpoint URL. Select your tool below to see exactly how to write your local test code. Same developer experience. Fraction of the cost and footprint. Where it matters most — RDS, ElastiCache, and ECS run real Docker containers. No…from ministack.org

  I've built a nice home server OSApr 2026 · lightwhale.asklandd.dk · ▲194

  ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

  Hiraeth – AWS EmulatorApr 2026 · github.com · ▲40

  With 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▲346

  Hi 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…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
