So I built a playground for it. **[Ghazi Khan](https://daily.dev/sources/pvpxyovlk)** · [@ghazikhandev](https://daily.dev/ghazikhandev) · 1 min read · 176 upvotes · 26 comments ## Summary Frontend System Design Playground is a free, staged interactive tool on IOCombats designed to simulate real frontend system design interviews. Unlike passive study methods, it walks users through requirements clarification, high-level architecture, component deep-dives, code implementation, and self-review against a checklist. Reference notes highlight commonly missed areas like performance and edge cases. Planned additions include AI, expert, and community review layers. ## Content Today, I'm launching the **Frontend System Design Playground** on IOCombats. Most system design preparation looks like this: Read a question → study a solution → watch someone explain it → move on. But real interviews don't work that way. You need to clarify requirements, make architectural decisions, explain your components, think about edge cases, and eventually write code. So I built a **staged, interactive interview experience** that lets you practice exactly that. You go through: 🔹 Requirements clarification 🔹 High-level architecture 🔹 Component deep-dive 🔹 Code implementation 🔹 Self-review against a practical checklist At the end, you can compare your approach against reference notes covering things candidates commonly miss, including performance, edge cases, and requirements. **And it's completely free.** We're building the next layer on top of this too: 🤖 AI Review 👨‍💻 Expert Review 👥 Community Review The goal is simple: **Make frontend system design practice as accessible as DSA practice.** Not another course. Not another collection of system design articles. **Actually practice the interview.** Try it on IOCombats: 👉 [https://iocombats.com/system-design-playground](https://iocombats.com/system-design-playground) This is another step toward our bigger goal: **helping frontend developers practice, prove their skills, and get hired faster.** #FrontendDevelopment #SystemDesign #ReactJS #NextJS #FrontendEngineering #InterviewPrep #IOCombats #SoftwareEngineering ## Community discussion Top comments from developers on daily.dev. **@dikshantsingh510** · 2 upvotes > Thanks for sharing this resource, I started my career as full stack developer a year ago.
