Interactive, step-by-step visualizations for coding patterns and system design — scrub through execution or build up HLD/LLD systems one piece at a time.
👋 Hi Product Hunt! I'm the maker of CodeSimulators.
I built this because I was tired of learning DSA and system design by memorizing solutions. Most platforms show the final code—but not why it works.
CodeSimulators lets you step through algorithms line by line with synchronized code, variable changes, call stacks, and visual execution.
It also includes visual explanations for LLD and HLD concepts to help connect theory with real interview problems.
I'd genuinely love your feedback:
Is the visualization intuitive?
What interview topics should we add next?
What felt confusing or unnecessary?
Thanks for checking it out, and I'll be here all day to answer questions! 🚀
