Is this actually useful? **[Raiyan Memon](https://daily.dev/sources/uyq31qrxhs7utomr5ywod)** · [@raiyan_memon](https://daily.dev/raiyan_memon) · 1 min read · 2 upvotes · 0 comments ## Summary A developer built Devscape, a tool for practicing system-design interviews by having users draw an architecture for a given problem (e.g. 'Design a URL Shortener') and then checking it against expected decisions, offering feedback and follow-up questions instead of a bare score. It currently covers 26 problems with 200+ checks. The creator is soliciting critical feedback from engineers who have prepared for system-design interviews, rather than promoting the product for sale. ## Content I was frustrated that most system-design preparation is passive — you watch videos, read solutions, and think you understand the architecture. So I built [Devscape](https://devscape.in). You get a problem like "Design a URL Shortener", draw the architecture yourself, submit it, and [Devscape](https://devscape.in) checks the design against a set of expected architectural decisions. Instead of simply giving you a score, it tells you what you missed and challenges you with follow-up questions. I have 26 problems and 200+ checks right now. **I'm not trying to sell it yet. I want brutal feedback from engineers who have actually prepared for system-design interviews.** What would make this genuinely useful to you? ## Similar posts on daily.dev - [I Tried 20\+ Websites for System Design Interview: Here Are My Top 10 Recommendations for 2026](https://daily.dev/posts/i-tried-20-websites-for-system-design-interview-here-are-my-top-10-recommendations-for-2026-huubtuly1) · Javarevisited · 5 upvotes · 0 comments --- Tags: [#career](https://daily.dev/tags/career), [#interview-questions](https://daily.dev/tags/interview-questions) [View this post on daily.dev](https://daily.dev/posts/i-built-a-system-design-interview-tool-is-this-actually-useful--ivuzpddrj) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/i-built-a-system-design-interview-tool-is-this-actually-useful--ivuzpddrj","headline":"I built a system design interview tool.
