AI Market: Multi-Vendor Marketplace Source Code with AI Search and Seller Dashboard

Building a multi-vendor marketplace from scratch is a long project. Beyond a storefront, you need separate seller accounts, store and product management, inventory, orders, delivery settings, promotions, reviews, returns and refunds, plus permissions that keep buyers, sellers and administrators apart. Founders often spend months on this plumbing before a single store goes live.

AI Market is a multi-vendor e-commerce marketplace that already has those pieces in place. Shoppers browse categories, search across products, brands and stores, and use a Find with AI product search. Sellers get their own dashboard to open one or more stores, publish products, run promotions, configure delivery zones and use an AI seller assistant for product titles, descriptions, keywords and business analysis. The frontend is plain HTML, CSS and JavaScript, with Supabase providing PostgreSQL, authentication, access policies and Edge Functions. The seller reports the platform is deployed on its own domain and is currently pre-revenue.

How it works

1. A shopper visits the site, searches or uses Find with AI, and browses categories, stores and trending products.
2. They open a product, add it to the cart and check out with an available payment option or cash on delivery.
3. Registered customers follow their orders, save favorites, receive notifications and can request a return.
4. Any user can choose "Become a seller", create one or more stores and publish products, using the AI assistant for titles, descriptions and keywords.
5. Sellers process orders, set prices, discounts, promo codes and delivery zones, and run ad campaigns from their dashboard.

Ways to monetize

A buyer could charge a commission on each sale, offer paid seller plans or store subscriptions, sell the built-in ad placements and seller advertising campaigns, charge for featured or trending positions, or offer the AI seller tools as a premium add-on.

Good to know

• Pre-revenue. The seller describes AI Market as a developed software asset, not an established business. The screenshots show a test store and test product, so there are no meaningful sales, sellers or customers to transfer.
• Payments. The seller notes that some payment operations need production provider configuration and verification before commercial use. Confirm which payment gateways are integrated and what is left to set up.
• AI provider. The listing does not name the AI model or API behind the search and seller assistant. Confirm which provider is used, and plan for your own API account and usage costs.
• Localization. The storefront has a language selector, but some strings in the screenshots appear in Russian and prices show in Armenian dram. Check translation coverage and currency settings for your market.
• Admin panel. The screenshots cover the storefront and seller dashboard only. Ask the seller for a walkthrough of the admin panel before buying.
• Domain and accounts. Confirm whether the current domain is part of the sale. You will need your own Supabase and Netlify accounts (or a transfer of the existing ones).
• Web only. This is a responsive web marketplace; no native iOS or Android apps are included.
