Credit — ByteByteGo

Preparing for a system design interview in 2025 is no small feat. The bar for technical interviews at companies like FAANG, top startups, and unicorns has never been higher.

Recruiters and hiring managers are looking for engineers who can think like architects, design scalable systems, and communicate trade-offs clearly.

If you’ve started your preparation, you’ve probably come across names like Exponent, DesignGurus, Educative, and ByteByteGo. Each platform promises to help you crack system design interviews — but which one actually delivers the best value in 2025?

After using all four, I can confidently say: ByteByteGo is the most complete and future-proof system design resource today. Here’s an in-depth comparison to help you decide.

By the way, if you are already familiar with ByteByteGo and always wanted to join them then I have a great news for you. They are now offering a big and rare 50% discount on their annual and lifetime plan, which makes them even more valuable.

I know them for 4 years and this is only the second time I have found they are giving discounts. So, if you always wanted to join ByteByteGo, now is the time.

Why System Design Prep Is Different in 2025?

Five years ago, learning a handful of classic system design problems — like designing a URL shortener or a chat system — was enough.

Today, interviewers expect deeper discussions about real-world scalability, distributed systems trade-offs, and even AI-powered architectures.

It’s no longer just about drawing a few boxes on a whiteboard. Modern interviews may touch on:

  • Designing highly available distributed databases
  • Architecting event-driven systems
  • Handling real-time streaming data
  • Building AI/ML-based services (recommendations, generative AI, RAG pipelines)

To stay competitive, you need current, visual, and structured content — not outdated blog posts or fragmented YouTube videos and that’s where a structured course like ByteByteGo or DesignGurus can help.

Let’s find out which one is the best resource for System Design in 2025

The Contenders: ByteByteGo vs. Exponent vs. DesignGurus vs. Educative

Let’s look at what each platform offers and how ByteByteGo stands out.

1️⃣ ByteByteGo (Alex Xu’s Platform)

Flagship Strengths

  • Visual Learning with Diagrams: ByteByteGo is famous for its beautiful, animated diagrams and infographics that break down even the most complex topics like consistent hashing, sharding, and load balancing.
  • Multiple Learning Tracks: Covers System Design Fundamentals, Coding Interview Patterns, Machine Learning System Design, Generative AI System Design, and Object-Oriented Design.
  • Books + Courses + Newsletter: Their best-selling books (System Design Interview — An Insider’s Guide, Coding Interview Patterns, and Generative AI System Design Interview) are complemented by amazing visual diagrams.
  • Lifetime Plan: ByteByteGo is offering a 50% discount on their lifetime plan — pay once, get access to all current and future courses, books, and updates.
  • Constantly Updated for 2025: Content is frequently refreshed with new FAANG-style questions and emerging technologies.

Ideal For: Engineers who want all-in-one preparation (system design, coding, AI) with visual, easy-to-digest explanations.

2️⃣ Exponent

Exponent built its reputation on mock interview, coaching and peer practice.

  • Strengths: Excellent for live mock interviews and behavioral prep. Their video explanations of real interview questions are helpful for seeing how experts think on the spot.
  • Limitations: System design content is decent but not as deep or structured as ByteByteGo. Their diagrams are simpler, and there’s no lifetime deal — only monthly or yearly subscriptions.

Best For: Candidates who want to practice live interviews with coaches or peers.

3️⃣ DesignGurus (Grokking the System Design Interview)

DesignGurus is famous for the original Grokking the System Design Interview course.

  • Strengths: Well-organized problem patterns (rate limiter, consistent hashing, etc.) and step-by-step solutions.
  • Limitations: The UI feels a bit dated, and some content hasn’t kept pace with modern distributed systems or AI/ML design questions. No coding or AI tracks, and no lifetime pricing.

Best For: Beginners who like pattern-based learning and want a cheaper starting point.

By the way, DesignGurus has many other Grokking courses to prepare for essential coding interview topics like OOP Design, System Design, Dynamic Programming etc and you can get access to all of their courses for a big discount by joining their All course bundle. You can also use code GURU to get 30% discount.

4️⃣ Educative

Educative’s Grokking series is another text-based and interactive resources which is great for System Design and Coding interview preparation.

  • Strengths: Great for engineers who prefer hands-on coding in the browser. Educative offers a Educative Unlimited Plan that provide access to more than 1200+ courses, projects, and cloud labs to learn in-demand tech skills including system design.
  • Limitations: Mostly text — diagrams are minimal, and system design content is less visual and modern compared to ByteByteGo.

Best For: Learners who enjoy interactive code execution and want a large library of general courses.

ByteByteGo’s Unique Edge? What Makes it best?

What makes ByteByteGo stand apart in 2025 isn’t just the breadth of topics — it’s the depth and clarity.

✅ 1. All-in-One Coverage

ByteByteGo now covers:

  • System Design Fundamentals
  • Machine Learning System Design
  • Generative AI System Design
  • Coding Interview Patterns
  • Object-Oriented Design

This means you can prep for every stage of a FAANG interview — from coding to large-scale distributed systems to AI architecture — under one subscription.

✅ 2. Visual, Diagram-First Teaching

Instead of paragraphs of text, ByteByteGo explains complex distributed systems with animated diagrams, flow charts, and architectural blueprints.

Visual learners (which includes most engineers) retain concepts much faster this way.

Here is an example of their visual excellence when it comes to designing a notification push system on interviews:

✅ 3. Lifetime Value

While competitors lock you into monthly or yearly plans, ByteByteGo’s lifetime plan — currently at 50% off — is a one-time investment that grows in value as new courses and books are added.

I bought their lifetime plan because its just 2.5x their annual plan and it provides best value as you will be getting all future content upgrades for free.
