AI app builder

Build your marketplace with AI — no code needed.

Vendors on one side, customers on the other, your rules in between. Tell Caffeine how your marketplace works in plain English — it builds the platform, hosts it, and updates it whenever you say. No coding, no servers, no dev team.

How it works

Describe

Say what you need the way you'd explain it to a colleague. No specs, no tickets.

Products launched by founders, not engineering teams.

  • Multi-tenant from day one
  • Stripe checkout built in
  • Your domain, your code

Everything a marketplace needs

Vendors and customers, separated

Role-based access gives vendors their own space to manage listings while customers browse and buy — and you run the whole platform from an auto-generated admin panel.

You approve who sells

New vendor sign-ups wait in an approval queue until you let them in, so quality stays in your hands from the first listing.

  • Listings your way

    Categories, fields, photos, prices, availability — the listing model matches your niche instead of a generic template, with search and filters to match.

  • Checkout with Stripe

    Take card payments through Stripe checkout with your own Stripe account, and unlock orders or bookings once payment completes.

  • Photos, files, and email

    Vendors upload images and documents to their listings, and your platform sends outbound email — confirmations, updates, newsletters — on paid plans.

  • Change the rules anytime

    New category, new vendor field, new approval step — describe it and the platform updates, with every change checked so live data is never lost. Export your code anytime.

Operations Director · Regional logistics company

"Tools that keep up with your processes — change the workflow and change the tool the same day, with nothing breaking and nothing waiting in a queue."

FAQ

Yes. You describe both sides — what vendors manage and what customers see — and Caffeine builds the roles, listings, search, and checkout around your rules. Vendors get their own space, and you manage the platform from an admin panel.

You decide. With an approval queue, vendor sign-ups wait as pending until you approve them from the admin panel — so you vet every seller before their listings go live.

Through the built-in Stripe checkout integration connected to your own Stripe account — customers pay by card and the platform unlocks the order or booking once payment completes. Automatic split payouts to individual sellers aren’t built in; how you settle with vendors stays in your hands.

Yes. Boats, tutors, wedding venues, vintage fonts — you describe the fields, categories, and search filters that matter in your market and the listing model follows them, not a template.

Yes. Run it on your own domain on paid plans, and export the code as a ZIP or to GitHub anytime. There’s no lock-in.
