Two courses called Grokking System Design. Which one should you buy?

Search for the Grokking system design course and you land on two different products with nearly the same name. One sits on designgurus.io. The other sits on educative.io. Design Gurus vs Educative is a genuinely confusing comparison, mostly because each page tells you theirs is the real one. I opened all four pages (two course pages, two pricing pages) on 20 August 2026 and wrote down what they actually said.

The headline finding, if you only read one line: the cheapest way to buy the Design Gurus course is a price that never appears on the Design Gurus pricing page.

Both sites claim to be the original Grokking

Design Gurus is blunt about it. Its course page says “DesignGurus.io is the birthplace of the ‘Grokking’ interview methodology”, and the same paragraph ends with “Accept no imitations, learn directly from the architects.” The listed author is Arslan Ahmad, described there as the founder of Design Gurus and a former FAANG hiring manager, with 500+ interviews conducted.

Educative doesn’t fight on that ground head-on. Its page opens with “For a decade, when developers talked about how to prepare for System Design Interviews, the answer was always Grokking System Design.” The author is Fahim ul Haq, listed as Educative’s co-founder and CEO, with distributed storage work at Meta and Microsoft behind him. The course is titled Grokking Modern System Design Interview, and the word carrying the weight there is “Modern”.

I can’t settle an ownership argument from two marketing pages and I won’t pretend otherwise. What I can tell you is that the two syllabi have drifted apart far enough that the question stopped mattering. You’re choosing between two courses now, not two copies of one.

What’s actually inside each one

Everything in this table was displayed on the two course pages on 20 August 2026.

Treat those last two labels as decoration. Both vendors want the page to look maintained on the day you arrive, and neither label tells you which lesson changed.

Design Gurus splits its 82 lessons across four chapters: approaching the interview (7 lessons), trade-offs (24), design problems (31), and a glossary of basics (20). The problem list is the classic set that made the course famous. TinyURL, Pastebin, Instagram, Dropbox, Facebook Messenger, Twitter, YouTube or Netflix, typeahead suggestion, an API rate limiter, Twitter Search, a web crawler, Facebook’s newsfeed, Yelp, Uber’s backend, Ticketmaster. A quiz hangs off most of them.

Educative’s course is shaped differently. It front-loads a long building-blocks arc (DNS, load balancers, databases, key-value store, CDN, sequencer, distributed monitoring, distributed cache, messaging queue, pub-sub, rate limiter, blob store, distributed search, distributed logging, task scheduler, sharded counters) and then runs a framework it calls RESHADED across the design problems. The problem list overlaps heavily with Design Gurus, then adds material the older course doesn’t carry: Google Maps, Quora, Google Docs, a payment system, a deployment system, a ChatGPT-style system, AI and ML data infrastructure, an LLM-powered support bot, and an AI code assistant.

That last cluster is the genuine content difference between them. If you’re interviewing somewhere that might ask you to design an inference-serving stack or a retrieval pipeline, Educative has lessons for it and Design Gurus doesn’t.

On raw counts, Design Gurus vs Educative isn’t close: 204 lessons against 82. I’d be careful with that, though. A lot of Educative’s count is building-block pages that run a couple of screens each, and lesson count is the easiest number on a course page to inflate. The reverse advantage gets less attention than it deserves. That 24-lesson trade-offs chapter on Design Gurus is a real chapter rather than scattered asides: latency vs throughput, proxy vs reverse proxy, token bucket vs leaky bucket, ACID vs BASE, strong vs eventual consistency, cache-aside vs read-through, push vs pull, read-heavy vs write-heavy. My opinion, and you’re welcome to disagree, is that this chapter is the best few hours available on either site, because trade-off vocabulary is the thing interviewers grade you on out loud.

Design Gurus vs Educative on price, checked 20 August 2026

One caveat belongs in front of this table. Both companies price by region and I was browsing from India, so these are not the numbers a reader in Berlin or Seattle will see. Design Gurus is upfront about it and prints “discounted price for India” beside each figure. Educative just rendered the whole page in rupees without comment.

The first row is the one worth your attention. The Design Gurus pricing page doesn’t sell the single course at all. It offers a monthly plan, an annual plan, two lifetime roadmaps, an all-courses lifetime bundle and a build-your-own bundle. Go to the course page instead and a box appears offering “Lifetime access to this course” at $26, down from $148, tagged “Save $122 today”. Same course, one click away, and roughly 40% of what the System Design Roadmap bundle costs. Its sibling courses were priced the same way while I was there, at $21 down from $123 apiece for System Design Fundamentals, Advanced Volume II, and the Crash Course.

Educative has no equivalent to that. You can’t buy the course by itself; you buy a platform subscription and the course arrives with it. The compare table listed “Grokking” Courses as included on all three consumer tiers, so the ₹6,737 Standard plan does get you the reading. The mock interviews embedded in the course are marked Premium, which means the cheapest tier gets the text and not the practice. AI Tutor allowances also step up by tier, at 5, 15 and 30 tutorials a month.

Both of those discounts are promotional, and you should read them that way. Educative’s page carried a countdown timer beside a “69% OFF” badge, reading a little over a day when I loaded it. Design Gurus showed “SAVE 89%” on the annual plan and “SAVE 94.78%” on the all-courses bundle. I didn’t come back a week later to check whether either timer resets, so treat the struck-through list prices as marketing furniture rather than as money anybody hands over.

Which one to buy

The honest answer to Design Gurus vs Educative comes down to one question: are you going to use the rest of the catalogue?

If no, buy the Design Gurus course outright. It’s a clean transaction. You pay once, you keep it, the trade-offs chapter is strong, and at $26 you’re not committing to anything. If yes, the subscription maths flips, because Educative’s tiers cover a catalogue of 2,000+ courses plus projects and cloud labs, and the marginal cost of the system design course inside that is close to zero. Interviewing somewhere that asks AI-infrastructure design questions pushes you the same direction.

Still unsure? Start free. Educative’s course carries a section of free system design lessons, and Design Gurus puts a “Get Started For Free” button on its course page. Two evenings of that will tell you which writing style you can tolerate for 20 hours, which matters more than any feature table including mine.

One thing I owe you plainly: I compared syllabi, structure and prices, not outcomes. I have not sat through 82 lessons on one site and 204 on the other, and any post claiming a head-to-head completion of both this month deserves a raised eyebrow.

The part neither course covers

Reading about how to design Uber is a different skill from talking about designing Uber for 45 minutes while someone interrupts your capacity estimate. Both vendors clearly know this. Design Gurus folds 5 AI coding mock interviews into its annual plan, and Educative sells 3 or 7 AI mock interviews a month depending on tier. When two rivals independently bolt the same feature onto a reading product, that tells you where reading stops working.

The failure mode is specific, and it isn’t knowledge. It’s freezing during requirements gathering, or spending 20 minutes on the data model and never reaching the scaling discussion at all. For structured practice against that, our AI mock interviews run timed sessions with feedback on pacing, and our system design interview guide walks the 45-minute clock end to end. Keep the system design cheat sheet open while you work through whichever course you pick. For the coding round, which is its own animal, NeetCode 150 vs Blind 75 answers the same buy-or-skip question.

Where these numbers came from

Each price and lesson count above was read off a vendor page on 20 August 2026: the Design Gurus course page, the Design Gurus pricing page, the Educative course page, Educative Unlimited, and the Educative pricing page. No third-party review sites were used, deliberately. Prices on this pair move, regional discounts move with them, and secondhand figures rot within weeks. If you’re reading this months from now, open those five links yourself. It takes about four minutes.

What I’d really want to know before spending money is which of the two you’d actually finish, and no table on any page can answer that one for you.
