How to access grokking system design content on Design Gurus and other learning platforms

Accessing Grokking System Design content requires understanding a distinction that confuses many engineers: the original Grokking the System Design Interview course was created by Arslan Ahmad and the Design Gurus team, and the fully updated official version now lives exclusively on DesignGurus.io. An earlier text-only version was previously hosted on Educative as a third-party distribution platform. That version has since been rebranded by Educative to "Grokking Modern System Design Interview" and is maintained independently by the Educative team—not by the original creators. In 2026, both platforms offer system design courses with "Grokking" in the name, but they are different courses with different authors, different content, and different update cycles. This guide maps exactly where to find each version, what you get on each platform, and which option fits your situation.

Key Takeaways

• The official, continuously updated Grokking the System Design Interview lives exclusively on DesignGurus.io. It includes 66 lessons, video walkthroughs, interactive architecture diagrams, and 2026 content (GenAI system design, streaming systems, cost-aware architecture).
• Educative hosts a separately maintained version called "Grokking Modern System Design Interview." It is a quality course with interactive text-based format but is not updated by the original Grokking creators.
• Design Gurus offers course-based pricing with lifetime access—pay once, own forever. Educative uses a subscription model (14.99–39/month) that includes access to 1,500+ courses beyond system design.
• Free Grokking content is available: Design Gurus publishes sample lessons, the 185+ article library, the System Design Cheat Sheet, the System Design Nuggets newsletter, and the grokkingsystemdesign.com portal with guides and curriculum overviews.
• The All Courses Bundle on Design Gurus provides the best value for engineers preparing for the complete interview loop—system design, OOD, coding patterns, and behavioral—with lifetime access at a discounted rate.

How to Choose Your Access Path

If you want the original Grokking methodology with lifetime access: Go to DesignGurus.io. Buy the core Grokking the System Design Interview course. Add Fundamentals (if beginner) or Advanced (if targeting L6+). This is the path 440,000+ engineers have taken.

If you want a subscription with broad course access beyond system design: Go to Educative. Subscribe for access to system design plus coding, behavioral, cloud, and ML courses. Best for engineers preparing for the complete interview loop who want one subscription covering everything.

If you want the best visual learning experience: Add ByteByteGo as a supplement to either Grokking or Educative. The visual diagrams build spatial memory that text-based courses cannot replicate.

If you are budget-constrained: Start with free resources: System Design Primer (GitHub), Design Gurus' 185+ article library, System Design Nuggets newsletter, and MIT 6.5840 lectures. These build a solid foundation at zero cost. Invest in a paid course when your interview is confirmed and timeline is defined. Many engineers report that the free article library on Design Gurus alone—covering company-specific guides, concept explanations, and cheat sheets—provides enough material to begin practicing before committing to a paid course.

If you are preparing for the complete FAANG interview loop: Consider the Design Gurus All Courses Bundle for lifetime access to system design, OOD, coding patterns, and behavioral prep. Alternatively, an Educative subscription provides access to system design alongside 1,500+ courses covering every interview type. The bundle approach saves money compared to buying individual courses and ensures coverage across every round in the interview loop—system design, coding, behavioral, and sometimes domain-specific rounds.
