Hello Devs, if you're preparing for a System Design interview in 2026, there is a good chance you've come across ByteByteGo and its founder, Alex Xu, author of another popular System Design interview resource and book, the System Design Interview - An Insider's Guide.
But with so many system design courses, books, YouTube channels, newsletters, and interview platforms available today, an important question remains:
Is ByteByteGo still worth it for System Design interview preparation in 2026?
After spending considerable time exploring the platform and Alex Xu's system design material, my answer is yes — especially if you prefer visual, structured, and practical explanations of complex distributed systems.
What makes ByteByteGo particularly interesting is that it has grown beyond the original system design material. The platform now covers areas such as Object-Oriented Design, Machine Learning System Design, Generative AI System Design, and Coding Interview Patterns, all the important topics you need to master to crack any FAANG-level interview.
