I’m a solo founder from Slovenia, working on a micro SaaS project called SwapBite. The idea is simple: You type in the junk food you're craving (like "Big Mac" or "Chips"), and AI instantly suggests a healthier alternative recipe – considering your diet, allergies, preparation time, and number of servings.

I built it because I was tired of getting generic advice like “just eat a salad” when I wanted something satisfying but still healthy. As someone into nutrition and tech, I wanted to use GPT-4 to nudge people into better choices without guilt.

I’m using:

OpenAI API for the food intelligence

NestJS + Prisma + Stripe for the backend

Tailwind + React for the frontend

Happy to share tech stack or details. It’s still early, but it works! Feedback, suggestions or roastings are all welcome. Live here: https://swapbite.com

Would love to hear:

Is this something you'd use personally?

Any ideas for how to make it more helpful/fun?

Thanks!
