Using OpenAI TTS, it costs ~$10 for ~10hrs. So at $15, margin is 50%.

The costs will go down in the future, I hope, and there are promising open-source projects coming up. Their quality is still pretty subpar and I have a comparison table I'll share soon on HN.

Otherwise it is Next.js on Vercel with Postgres DB.

Hope it helps
