"Hey Product Hunt! 👋 I built Mockmate to solve my own interview anxiety. I wanted a completely immersive experience, so I hooked up the Web Speech API to a 3D Spline model and powered the logic with a decoupled Node/Express backend. The app worked beautifully (you can see the full voice interaction in the YouTube demo video!). But I quickly realized a massive problem: letting thousands of people do live, voice-to-voice AI interviews would bankrupt me in API costs overnight. 😅 Because the architecture was so painfully hard to build (getting the audio latency down and the CORS policies playing nice took me 50+ hours), I decided to pivot. Instead of paying for everyone's API calls, I’ve packaged up the entire React/Node codebase into a boilerplate. > 🎥 See it in action: Watch the YouTube demo in the gallery to see the live voice agent. ✨ Feel the UI: Click the website link to play with the Vercel frontend (Next-Gen Glassmorphism & Spline 3D). 🚀 For Developers: If you want to build your own Voice AI app and skip the 50 hours of backend setup, you can grab my exact full-stack codebase here: https://pb-digital-labs.lemonsqu...
