The Challenge

The client needed a single marketplace where the owning company and independent public users could list, buy and sell through two commerce modes: competitive auction bidding and instant fixed-price purchase. Existing off-the-shelf platforms supported only one mode, forcing users onto separate systems. The client also needed role-based dashboards for admins, verified sellers and buyers.

Our Solution

Cyberbeak built a full-stack hybrid marketplace using Python/Django and Django REST Framework for the backend API with a Next.js frontend. A dual-mode listing engine lets sellers activate Auction Mode (configurable bid increments, reserve prices, anti-sniping auto-extension) or Fixed-Price Mode on any product. Redis pub/sub and WebSockets deliver instant bid updates, Celery handles auction closing and alerts, and Stripe manages split payments, escrow holds and seller payouts.

The Results

The client now runs auctions and fixed-price sales on one platform, with separate dashboards for admins, sellers and buyers. We do not publish client-specific figures for this project.

Frequently Asked Questions

How does the platform prevent bid sniping in auction mode?

If a bid is placed in the final minutes of an auction, the closing time is extended automatically so other bidders have a fair chance to respond.

How do auction and fixed-price modes work on the same marketplace?

Sellers can activate Auction Mode or Fixed-Price Mode on any listing. Auction Mode supports configurable bid increments, reserve prices and auto-extension. Fixed-Price Mode lets buyers purchase immediately. Both run side by side with one buyer experience.

Why were Django and Next.js chosen for this marketplace?

Django and Django REST Framework provide a robust backend for multi-role permissions, listings, bid histories and payment escrow. Next.js delivers server-rendered, SEO-friendly product pages with fast live bidding updates.

How are payments and payouts handled?

Stripe integration manages split payments, escrow holds and automated seller payouts, and Celery handles scheduled tasks such as auction closing, outbid alerts and winner notifications.

Can Cyberbeak build a multi-vendor auction or e-commerce marketplace?

Yes. Marketplace development is a core Cyberbeak specialism, including auction and fixed-price modes, role-based seller, buyer and admin dashboards, real-time bidding, payments and seller payouts.
