Build a Marketplace
with AI

Two-sided platforms with listings, search, reviews, and payments. Connect buyers and sellers without months of custom development.

Sharetribe charges $99-299/mo. Arcadier starts at $249/mo. Building from scratch takes months. GenMB generates the entire marketplace in hours with Agent Mode.

Why Build a Marketplace?

Marketplaces connect people who have something to offer with people who need it. They're one of the most powerful business models because they create network effects—every new seller attracts more buyers, and every new buyer attracts more sellers. Airbnb, Etsy, Fiverr, and Uber are all marketplaces.

The challenge has always been the technical complexity. A marketplace isn't one app—it's two apps (buyer and seller) that share a platform. Add payments, search, reviews, and user management, and you're looking at months of development and significant cost.

GenMB eliminates that barrier. Agent Mode generates both sides of the marketplace, integrates Stripe Connect for payment splits, uses Supabase for data persistence, and adds Algolia for search. The RBAC service handles seller/buyer role enforcement. You get the full stack in hours instead of months.

Everything a Marketplace Needs

Agent Mode builds both sides of your platform with integrated payments, search, trust systems, and role-based access control.

Two-Sided Architecture

Separate buyer and seller views with dedicated dashboards for each side. Sellers manage listings, track orders, and view analytics. Buyers browse, compare, and purchase—all from purpose-built interfaces generated by AI.

Built-in Search and Discovery

Faceted filters, category navigation, and full-text search powered by the Algolia plugin. Users find what they need fast, whether browsing by category or searching for something specific. Discovery is what makes or breaks a marketplace.

Trust and Reviews

Rating systems, verified profiles, and review workflows that build trust between strangers. Buyers leave reviews on purchases, sellers build reputation over time. Trust infrastructure is the foundation every marketplace needs.

Payment Processing

Stripe Connect handles marketplace payment splits automatically. Buyers pay, the platform takes a cut, sellers receive their share. Escrow, refunds, and payouts—all handled through the Stripe plugin without custom payment code.

How to Build a Marketplace with GenMB

From marketplace model to deployed platform in five steps.

1

Define Your Marketplace Model

Decide what's being exchanged—services, physical goods, digital products, rentals. Define who your sellers and buyers are. The clearer your marketplace model, the better GenMB can structure both sides of the platform.

2

Describe Both Sides to GenMB

Use Agent Mode to describe the full marketplace: seller onboarding, listing creation, buyer browsing, checkout flow, and order management. Agent Mode handles complex multi-screen applications autonomously, building each side of the marketplace step by step.

3

Enable Stripe for Payments and Supabase for Data

Activate the Stripe plugin for marketplace payment splits (Stripe Connect) and Supabase for storing listings, user profiles, orders, and reviews. These plugins integrate directly into the generated code—no manual wiring required.

4

Add Search with Algolia Plugin

Enable the Algolia plugin for fast, relevant search across all listings. Faceted filtering by category, price range, location, and custom attributes. Search quality directly impacts marketplace conversion rates.

5

Deploy and Onboard First Sellers

Deploy to a subdomain, invite your initial sellers, and start building supply. Use the RBAC service to enforce seller/buyer roles and permissions. Iterate based on feedback from both sides of your marketplace.

Marketplace Questions

Can I build a two-sided marketplace with AI?▼
Yes. GenMB's Agent Mode builds complex multi-screen applications, including two-sided marketplaces with separate seller and buyer experiences. Describe your marketplace model—what's being exchanged, the seller flow, and the buyer flow—and Agent Mode generates the full application with listings, profiles, search, and checkout.
How do marketplace payments work?▼
GenMB uses the Stripe plugin with Stripe Connect to handle marketplace payment splits. When a buyer pays, Stripe automatically routes the platform fee to your account and the remainder to the seller. This covers escrow, refunds, and seller payouts without any custom payment infrastructure.
Can sellers manage their own listings?▼
Yes. The generated marketplace includes a seller dashboard where sellers create, edit, and manage their listings. The RBAC service enforces role-based permissions so sellers only access their own content while buyers have a separate browsing and purchasing experience.
How do I add search and filtering?▼
Enable the Algolia plugin during generation. It provides full-text search, faceted filtering (category, price, location), and relevance ranking out of the box. For simpler needs, GenMB can generate client-side filtering. Algolia is recommended for marketplaces with more than a few hundred listings.
