QUICK VERDICT
Bottom line: Pick Educative if you want one affordable subscription covering coding, system design, ML, and 2,100+ other developer courses in an interactive format. Pick DesignGurus if system-design or coding interviews are your sole focus and you want the original “Grokking” courses with lifetime access and human mock interviews.
- Educative: $139–$239/year depending on tier, 2,100+ courses, interactive lessons, breadth
- DesignGurus: ~$149/year or ~$445 lifetime on its standing sale, narrow interview focus, original Grokking author, real-engineer mocks
- Most people: Educative wins on value and breadth; DesignGurus wins for a single-minded system-design push

A lot of the confusion between these two platforms comes from one fact: the famous “Grokking” interview courses were originally published on Educative, then their creator, ex-Meta and Microsoft engineer Arslan Ahmad, launched his own platform — DesignGurus.io — and moved his courses there. Today, the flagship Grokking the System Design Interview and Grokking the Coding Interview courses authored by him live on DesignGurus, while Educative continues to publish its own interview-prep courses under the Grokking name, built by its in-house and partner engineers.
So when you search for “Grokking the System Design Interview,” you can land on either platform. They are not the same product. That is the real decision in front of you — not which course is better, but which platform fits how you want to study and pay.

Pricing: subscription vs lifetime
This is where the two diverge most. Educative is a pure subscription, now sold in three tiers: $139, $189 or $239 for the year (listed at $278, $378 and $478), where the difference is the AI mock-interview allowance rather than the catalogue. All three unlock the entire catalog. Stop paying and you lose access, but while you are subscribed you can study anything — coding, system design, ML, cloud, you name it.
DesignGurus offers both a subscription and lifetime options, and when we checked its pricing page on 10 September 2026 a sitewide 60%-off sale was running across all of them: the annual subscription at $149.20 (against a $31.08/month list, about $373 a year), lifetime access to all current and future courses at $445 (list $3,678.88), and single-track lifetime “roadmap” bundles at $136 for coding and $152 for system design (lists $411 and $459). Compare on the sale prices, because that is what you would pay — but check the page on the day: its countdown was showing zero days remaining while the sale was still live, which is a sale that renews rather than one that ends. At those prices the up-front lifetime number is no longer far above a year of Educative, which is what it used to be.
For a single interview cycle, Educative is clearly cheaper. For someone who wants to own a specialized system-design library permanently, DesignGurus’ lifetime bundle can be the better long-run value. Prices shift with regional and seasonal discounts on both sides, so confirm the current number at checkout.
Who should pick Educative
Choose Educative if you want more than interview prep. The subscription is the better deal when you will use the platform for ongoing skill-building — picking up a new language, brushing up on cloud or ML, and prepping for interviews from the same account. The interactive, in-browser format (no local setup, run code right in the lesson) is genuinely pleasant for learning, and the breadth means one subscription serves you long after the interview is over. For most working developers, that combination of price and range makes Educative the default pick.

Who should pick DesignGurus
Choose DesignGurus if system-design or coding interviews are your single, urgent focus and you want the original material straight from the engineer who wrote it. Its narrower scope is a feature here: the platform is built around interview prep and nothing else, the lifetime option means the content is yours across multiple job searches, and the paid mock interviews with real FAANG-experience engineers are a level of feedback Educative does not match. If you are doing a focused system-design sprint and budget is secondary to getting the canonical course plus human mocks, DesignGurus is the honest recommendation — even though we do not earn a commission from it.
Frequently asked questions
Is Educative or DesignGurus better for system design interviews?
For the canonical system-design course from its original author plus human mock interviews, DesignGurus is stronger. For system design as part of broader, cheaper, ongoing learning, Educative is the better value. Both teach the material well.
Are the Grokking courses the same on both platforms?
No. The original author moved his Grokking courses to DesignGurus. Educative publishes its own interview-prep courses under the Grokking name, built by its in-house and partner engineers. The content and approach differ.
Which is cheaper?
Educative on list, but the gap has closed. Educative’s entry tier is $139 a year; DesignGurus’ annual subscription was $149.20 on its standing sale when we checked on 10 September 2026. DesignGurus’ lifetime bundle at $445 on the same sale is now the stronger long-run value if you will revisit the material across multiple job searches.
Does Educative have an ML interview course?
Yes — see our Grokking the Machine Learning Interview review. It is part of the Educative subscription.
Can I try either one before paying?
Educative offers a free trial. DesignGurus provides previews of some lessons. Always confirm current trial and refund terms at checkout.
