How AppGenie builds your marketplace app

A look at the multi-agent pipeline that turns your prompt into a generated codebase.

  1. 1

    A1 reads the prompt

    IntentClassifier sees "marketplace" and routes to the two-sided pipeline preset.

  2. 2

    A3 drafts roles and flows

    PRDWriter outlines buyer and seller flows, the data model, and the Stripe Connect payment split.

  3. 3

    A4 + A5 generate the app

    Architect plans the role-based nav and messaging; CodeGenerator wires listings, chat, and checkout.

  4. 4

    A6 validates the build

    Validator runs a build check; you get a live preview to test buyer and seller side end-to-end.

The bottom line

A two-sided marketplace is the kind of project that scares founders because of the chicken-and-egg problem. AppGenie removes the technical half: you get listings, chat, payments, and reviews in one pipeline run, so you can spend your time on supply and demand instead of plumbing.
