Relist – P2P Marketplace with Web and Flutter App

Relist is a peer-to-peer marketplace solution for building a platform where people can buy and sell pre-owned products. It includes a modern Next.js web application, a PostgreSQL backend, a web-based admin console and Flutter source code for Android and iOS.

Buyers can discover nearby listings, browse product details, save favourites, contact sellers and negotiate through messages, offers and counter-offers. Sellers can publish products, manage inventory, track offers and maintain their marketplace profiles.

The platform also includes administrative tools for listing moderation, identity verification, member management, reports, analytics and transaction records.

The package provides web and mobile source code, PostgreSQL migrations, Prisma configuration, seed scripts, tests and installation documentation.

Payment and deployment information: Payments operate in sandbox mode by default. Live Stripe and bKash payments require the buyer's own merchant accounts and configuration. Live payouts are reconciled manually, and the current payment adapters settle in BDT. Currency display settings do not provide automatic currency conversion.

Relist is developer-oriented source code. Hosting, third-party services, app signing, developer accounts and store submissions are the buyer's responsibility.
