Learn system design by building it. Drag in components that carry real capacity, latency and cost (load balancers, caches, queues, databases, LLM services), push traffic through your design in the browser, and watch p99 latency, errors and saturation as it runs. Start free with a 151-lesson course in 7 tracks and 5 practice problems. Pro adds every graded HLD and LLD problem (70+), an open sandbox, and AI mock interviews, spoken or typed, with a scored report.

Hi Product Hunt 👋
I'm Vishal, founder of Agnicode. We developed ArchiDepth that is how we think system design should be learned: by building it.
AI now writes working code in minutes. What it can't own is the decision behind it: where the data lives, what fails first, what it costs at ten times the load. That is what system design interviews test, and most prep stops at drawing boxes that nobody ever runs.
ArchiDepth runs them:
Build a design on a canvas from components with real capacity, latency and cost characteristics
Push traffic through it in your browser and watch where pressure collects
Every practice problem is graded by what your design did under load, and the same seed always gives the same score
Then defend it in a timed AI mock interview, spoken or typed, with a report that quotes what you said
Free: the whole course, no account needed (151 lessons in 7 tracks, from how a request crosses the network to RAG and agents), plus 5 practice problems on the simulator with a free account.
Pro: $29 a month (₹999 in India) for every problem, the open Sandbox and the AI features. The tutor, coach, reviews and mock interviews run on prepaid credits.
New this week: a 14-part tutorial series, about two minutes per feature and recorded in the product itself: https://www.youtube.com/playlist...
I'd love specific feedback:
Try the free problem "Rate limits for a public address-lookup API". Do the simulator's numbers feel believable?
Which system or interview question should we add next?
What confused you in the first five minutes?
I'll be in the comments all day. Thank you for taking a look 🙏
