A curated awesome-list repository compiling step-by-step guides for recreating popular technologies (databases, shells, compilers, renderers, etc.) from scratch. It is maintained by CodeCrafters and serves as a free companion resource to their hands-on programming challenges.
Use cases
- find tutorials to build a database from scratch
- learn how git works by implementing it
- build your own programming language or interpreter
- find a guide to write a toy operating system
- learn networking by building a TCP stack or web server
- find free step-by-step guides for deep learning fundamentals
- recreate redis or docker to understand internals
When to choose
- you learn best by building things from scratch
- you want free, curated, community-vetted tutorial links across many technologies
- you want to go deep on how everyday tools work internally
- you need project ideas for portfolio-building or interview prep
When to avoid
- you need structured courses with automated feedback and grading rather than links
- you want a library or tool to install and use in production
- you are a complete beginner looking for a single linear curriculum
- you need officially maintained documentation for a specific technology
