DesignGurus.io Review 2026 — Is DesignGurus.io a Good Place for Coding Interview Preparation?

Hello guys, as tech interviews get tougher, many aspiring engineers look beyond LeetCode and books for structured, pattern-driven prep. If you are one of them and looking for best coding interview resources then you have come to the right place. Earlier, I have shared best coding interview courses and books and now I will explain why DesignGurus.io is a great place to prepare for coding interviews in 2026. If you don't know, DesignGurus.io—the platform behind the now-famous Grokking series of courses. But in 2026, with so many options, is it still worth your time and money?

Let's explore what DesignGurus offers, how it stacks up, and who will benefit most from it.

Codemia.io vs DesignGurus.io in 2026: Which is Better for System Design Interviews?

Hello guys, when it comes to prepare for System Design interview you now have many options like Codemia.io, DesignGurus.io, ByteByteGo, Exponent, Educative, and Udemy but the two which stands out in this list is the first two, Codemia.io and DesignGuru.io.

These two platforms have gained attention for helping candidates prepare for these challenging interviews, but if you have to choose one which one should you choose? DesignGurus.io or Codemia.io?

Well, we will find in this article. This article compares these resources to help you decide which might be the best fit for your preparation needs.

What is DesignGurus.io ?

DesignGurus.io is a well-established platform known System design and Coding interview preparation for its “Grokking the System Design Interview” and “Grokking the Advanced System Design Interview” courses.

Created by ex Amazon and ex Facebook guys, DesignGuru.io has built a strong reputation in the tech community for its comprehensive approach to system design preparation in last few years.

It was also one of the first few resources which I used for preparing for System design but things have changed since then.

Now a days System design interview have become more and more competitive and the limited number of questions set Designguru.io have many not b sufficient, that’s where Codemia.io can help you.

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.

And, when it comes to System Design Interview preparation, today, the most talked-about platforms for system design prep are:

• ByteByteGo (by Alex Xu, author of System Design Interview books)
• DesignGurus.io (founded by ex-FAANG engineers, hands-on system design courses and mock interviews)
• Educative.io (a massive interactive learning library with system design tracks and practice content)

But which one is actually the best for you? Let’s break them down one by one.
