Mutexmachine
System design teaching tool
Use Mutexmachine to assign system design exercises, compare architectures, and teach post-mortem reasoning without accounts.
Assignments without accounts
Mutexmachine is built for account-free teaching. Classroom mode creates shareable URLs for curriculum topics or sandbox drills, and student results aggregate locally. That keeps setup small and avoids turning a lesson into platform administration.
A teacher can assign the same traffic curve, SLA, budget, and component set to a class, then compare how different teams solved the same backend problem.
Useful classroom artifacts
The end of a run is not just a score. Students get a post-mortem with timeline, impact, root cause, contributing factors, and what would have helped. Exports make it easy to discuss decisions after the timer stops.
For example: create a sandbox flash-sale drill, share the URL, ask students to survive the peak, then compare which teams spent on cache, CDN, queues, replicas, or rate limiting.
