Comparison · last reviewed April 2026
Video-based interview prep platform best known for its algorithms course; SystemsExpert is its system design counterpart.
AlgoExpert's SystemsExpert offers polished videos for a curated set of ~25 problems. SystemCity gives you 5x the problem count, an interactive canvas to build on, AI feedback on every design, and a free tier to try before you pay.
AlgoExpert built a strong reputation around polished video explanations of coding problems. SystemsExpert applies the same format to system design — high-production videos walking through a curated set of problems. The format is one-way (you watch), the catalog is small, and the bundle gets expensive when you add multiple "Expert" products.

Strengths
Limitations
If you specifically prefer learning from polished video walkthroughs and the curated set is enough for your needs, the production quality is genuinely good. For most candidates, however, you get more value from SystemCity's 120+ interactive problems with AI feedback at a lower entry price — and you can always supplement with free YouTube content for the video format.
Yes. Many candidates use AlgoExpert for algorithms (its strongest product) and SystemCity for system design (where its interactive canvas and large catalog lead). SystemsExpert and SystemCity overlap directly, so you typically only need one for system design.
SystemsExpert covers around 25 classic problems. SystemCity offers 120+ across four difficulty tiers — including the classic FAANG problems (URL shortener, Twitter, chat) plus many modern systems (collaborative editing, real-time gaming, ride-sharing, ML inference platforms, payment processing, observability pipelines, and more).
Browse 120+ system design problems, build architectures on the interactive canvas, and get AI feedback on your designs. No credit card required.
