ReqFlow is an interactive engineering playground where you learn by doing, not watching. Explore real system architectures like WhatsApp, Netflix, and Uber, trace live requests, trigger failures, and rebuild systems from memory. Practice System Design, DSA, React Native, and Forward Deployed Engineering with interactive visualizers, interview mode, capacity estimation, drag-and-drop design, AI feedback, and hands-on lessons that prepare you for real engineering work.
👋 Hi Product Hunt!
I'm the solo developer behind ReqFlow.
I built ReqFlow because I felt that most programming courses rely heavily on long videos and passive learning. Students finish hours of content but often struggle to apply what they've learned when building real products or preparing for interviews.
ReqFlow takes a different approach. Every lesson is designed to be interactive, practical, and focused on real engineering problems.
Today the platform includes four learning tracks:
🚀 Data Structures & Algorithms with interactive visualizers
🏗️ System Design using real-world architectures and a drag-and-drop builder
📱 React Native with practical lessons for building production-ready mobile apps
🤖 Forward Deployed Engineering, covering AI applications, RAG, MCP, automation, and modern engineering workflows
The goal is simple: help students build practical software engineering skills instead of just collecting certificates or completing another video course.
This is just the beginning, and I'm continuously improving the platform based on feedback from students and developers. I'd love to hear what you think, what you'd like to see next, and how I can make ReqFlow even better.
Thanks for checking it out! ❤️
Love this—Reqflow is a great addition to the space. Wishing the team a strong launch! 🚀
Traced a WhatsApp message through the visualizer and the live request flow actually made queueing and retry logic click for me in a way videos never did. Wish more prep tools felt this hands on.
