ByteByteGo teaches system design with visual explanations and courses. InfraSketch lets you build system designs hands-on with AI-generated diagrams. Combine both for the most effective interview preparation.
Or try an example:
Describe your system in natural language
AI generates a complete architecture diagram
Refine your design through conversation
Watch your diagram update in real-time
Generate comprehensive design documentation
Manage multiple designs with session history
ByteByteGo teaches system design through curated visual content and Alex Xu's books. InfraSketch lets you practice building systems yourself with AI-generated diagrams and auto-generated design documents. One teaches the theory, the other provides hands-on practice.

AI-Powered Interactive System Design Tool
System Design Learning Platform by Alex Xu
ByteByteGo is a system design learning platform created by Alex Xu, author of the System Design Interview books (Vol 1 and Vol 2). It offers a newsletter, course content, and visual explanations of system design concepts and real-world architectures.
ByteByteGo is a learning platform with pre-made visual explanations and courses. InfraSketch is an interactive tool where you generate your own architecture diagrams from descriptions. ByteByteGo teaches you how systems work; InfraSketch lets you practice designing systems yourself.
They serve different purposes. ByteByteGo is excellent for learning concepts and studying real-world architectures through its books and visual content. InfraSketch is better for hands-on practice, where you describe systems and build diagrams interactively. The most effective approach is to learn from ByteByteGo and practice with InfraSketch.
No. ByteByteGo provides pre-made visual explanations of system design concepts. InfraSketch generates custom architecture diagrams from your natural language descriptions, letting you build any system you can describe and refine it through conversation.
Yes. You can take any problem from the System Design Interview books (designing a chat system, rate limiter, news feed, etc.) and build the architecture in InfraSketch. This gives you hands-on practice with the exact problems covered in the books.
Turn ByteByteGo concepts into interactive architecture diagrams. No signup required.
