ScaleDojo is where engineers stop watching system design videos and start building real architectures with their own hands. 220+ interactive challenges across HLD, LLD, API design, and GenAI pipelines. Every challenge is a real system. An AI architect reviews your work and tells you exactly where it breaks. Free to start. Built for engineers who are tired of theory without practice.
Fifty years in this industry teaches you one thing above everything else: nobody ever got good at building systems by watching someone else build them.
ScaleDojo figured that out and built something I wish had existed three decades ago.
You get 70 High-Level Design challenges, 50 LLD schema missions, 50 API design levels, and 50+ GenAI pipeline labs covering RAG architectures, LLM pipelines, and vector databases. Not simulations. Not multiple choice. You drag, connect, and architect real systems the same way you would at 2am before a production launch.
Then an AI architect reviews your design and gives you the kind of honest feedback a grumpy senior engineer gives you when the stakes are real.
There's a global leaderboard. There's a structured roadmap. And it's free to start.
I've watched a hundred tools promise to teach system design. Most of them taught people how to talk about system design, which is a very different thing. ScaleDojo is the first one I've seen that just puts you in the room and says: here's the problem, now build it.
If you've ever gone blank in a system design interview, not because you weren't smart enough but because you had never actually practiced the thing, this was quietly built for you.
Go in. Build something. Break it. Learn why. That's how it has always worked.

Who hunted ScaleDojo?
ScaleDojo was hunted by ScaleDojo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
