ByteByteGo Courses vs ByteByteGo Books? Which one is better for System Design Interviews in 2026?

Hello guys, when preparing for system design interviews, one name that consistently comes up is ByteByteGo. Founded by Alex Xu, the author of System Design Interview — An Insider’s Guide, in last few years, ByteByteGo has become one of the most trusted resources for learning system design. But with both ByteByteGo books and the ByteByteGo online course available, many learners face the same dilemma: Which one should I buy? Which one is better for System Design Interviews and Coding interviews?

I Just found LeetCode for System design Interview and Its Amazing

Hello guys, If you’re preparing for system design interviews — especially for FAANG or top-tier tech roles — you’ve likely encountered Bugfree.ai.  In the past, I have tried various online platforms to learn System Design like ByteByteGo, Exponent, and DesignGurus.io, but one thing I missed is online interactive practice, something like LeetCode where I can solve problems, get it evaluated and also get points to move up the leader board.

ByteByteGo vs Educative.io vs DesignGurus.io: Which System Design Course Is Best for 2026?

Hello guys, System design interviews remain one of the most difficult hurdles for software engineers in 2026. Unlike coding interviews, where you can practice data structures and algorithms with LeetCode-style problems, system design requires a mix of architectural knowledge, trade-off analysis, and real-world problem-solving skills. With FAANG and top-tier startups continuing to emphasize these interviews, software developers and engineers need the right preparation resources.
