Hi Product Hunt! System design is one of the hardest skills to practice alone. Most resources help you study architectures, but very few let you design systems yourself and get feedback. 𝐒𝐨 𝐈 𝐛𝐮𝐢𝐥𝐭 𝐏𝐫𝐢𝐬𝐦 A platform designed to help engineers learn, practice, simulate, and evaluate system design in a structured way. Prism currently has four core modes: 1. 𝐑𝐨𝐚𝐝𝐦𝐚𝐩 𝐌𝐨𝐝𝐞 A structured path to learn system design and distributed systems concepts step by step. 2. 𝐋𝐞𝐚𝐫𝐧 𝐌𝐨𝐝𝐞 Explore 25+ system design case studies with step-by-step architecture breakdowns, reasoning behind each component, alternatives, FAQs, and simulations. 3. 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞 𝐌𝐨𝐝𝐞 Design system architectures yourself and experiment with different approaches to solve real system design problems. 4. 𝐄𝐯𝐚𝐥𝐮𝐚𝐭𝐞 𝐌𝐨𝐝𝐞 Simulate a real system design interview: define functional and non-functional requirements, answer MCQs and trade-off questions, and receive AI-powered evaluation and feedback. The goal behind Prism is simple: Move system design preparation from passive learning → deliberate practice. You can try Prism here: https://hldsimulator.onrender.com/ I’d really appreciate feedback from the Product Hunt community. Two things I’d especially love your thoughts on: 1. What system design problems should I add next? 2. What would make system design practice more useful for you? Thanks for checking it out!
