About ChaosBench
ChaosBench is an interactive system design simulator that allows engineers to practice architecture design through a structured four-stage process. Users drag and drop components onto a real-time canvas to build systems, then face live scenario-specific incidents that test resilience. The tool evaluates designs based on scalability, resilience, and cost, providing a detailed breakdown of performance with the primary bottleneck identified. Each session follows a mock interview loop—clarify requirements, architect the system, handle chaos incidents, and defend tradeoffs against AI cross-examination. The platform offers curated scenarios for mid, senior, and principal-level engineers, with additional features like daily streaks, career score tracking, and scenario sharing for comparison. Sessions are graded per dimension, and users can retry scenarios multiple times depending on their plan.
