Top 7 ByteByteGo Alternatives for System Design Interviews (2026 Guide)

Looking for a ByteByteGo Alternative for System Design Interview Prep? These 6 websites and platforms fits the bill

System Design has become one of the hardest parts of software engineering interviews.

You can solve 500 LeetCode problems and still fail the interview — because System Design tests something completely different: how you think, how you make trade-offs, and how you build systems that scale.

For the past few years, ByteByteGo has become one of the most popular resources for System Design preparation. And for good reason — it explains complex distributed systems in a simple, visual, and structured way.

However, ByteByteGo is a premium resource, and its price can be a barrier for many developers, especially students and early-career engineers. While the 50% discount on ByteByteGo lifetime plan does makes it a bit affordable, still it can be out of reach for many folks.

The good news?

There are several excellent ByteByteGo alternatives like Codemia, Bugfree.ai, two of the most popular website for system design prep.

Then there’s Exponent, Educative, DesignGurusthat offer high-quality System Design training — often at a lower cost or with different learning styles.

In this article, I’ll share the Top 7 ByteByteGo alternatives, and also explain when ByteByteGo is still worth it — especially now that they are offering a 50% discount.
