GitHub – I tried to build AWS S3 from scratch
Over the past few years I’ve been thinking about how I could build SaaS and deploy it on my own infrastructure without needing to use any cloud platforms like AWS or GCP. In this repo I document my progress on building a clone of AWS S3 that functions the same as S3 using an exclusively open-source technology stack.
GitHub – I tried to build AWS S3 from scratch launched on May 18, 2024 with 21 votes, #841 of 4,539 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
This project documents an open-source implementation of AWS S3, built from scratch using only open-source technologies. It enables developers to deploy S3-compatible object storage on their own infrastructure without relying on cloud providers like AWS or GCP. The repository tracks the creator's progress in replicating S3's functionality, offering an alternative for teams seeking self-hosted, cloud-independent storage solutions.

Talanoa▲340Hi 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…
