Build Your Own X

Build Your Own X is a curated index of tutorials that teach programming by rebuilding familiar technologies from scratch.

What you can build

The collection includes guides for databases, shells, Git, Docker, BitTorrent clients, neural networks, 3D renderers, blockchains, command-line tools, and other systems.

Why it matters

Instead of only reading theory, developers can follow practical projects that expose how real tools store data, parse input, communicate over networks, and manage state.
