Hey Product Hunt! 👋 I’m excited to introduce WhatStack—a platform that lets you explore the tech stacks and SDKs behind popular mobile apps. Ever wondered what powers apps like Tesla, Google Pay, or Instagram? With WhatStack, you can quickly discover if they use React Native, Flutter, Firebase, Stripe, and much more. I built WhatStack to help developers, marketers, and product teams easily access tech insights, make informed decisions, and better understand market trends. You can also request analysis for apps you're curious about! I’d love your feedback, questions, and suggestions to improve the tool further. Happy to answer anything here! Thanks for checking it out! 🚀
