The implementation is 10k lines of code, which is 100x less code than Twitter wrote to build and scale their original consumer product, which was extremely similar. This repository can easily be adapted to make any Twitter-like social network.<p>> The project README includes instructions for running an instance locally on your machine, which is easy to do. To help with understanding the codebase, we've left many comments throughout the code.<p>> Finally, our blog post from two weeks ago is a deep-dive exploration of how this codebase works<p><a href="https://blog.redplanetlabs.com/2023/08/15/how-we-reduced-the-cost-of-building-twitter-at-twitter-scale-by-100x/" rel="nofollow noreferrer">https://blog.redplanetlabs.com/2023/08/15/how-we-reduced-the...</a><p>Previous discussion: <a href="https://news.ycombinator.com/item?id=37137110">https://news.ycombinator.com/item?id=37137110</a><p>There's also this "Introducing Rama" video: <a href="https://www.youtube.com/watch?v=jcvxGvzjLHg">https://www.youtube.com/watch?v=jcvxGvzjLHg</a>
