Windsurf + Marketplace

Built a marketplace with Windsurf?
We'll make it production-ready.

Marketplaces are among the hardest apps to build well because they serve two distinct user types (buyers and sellers) with different needs, handle money flowing between users, and require trust systems. AI tools can scaffold the UI quickly, but the critical backend logic — escrow, disputes, ratings, and split payments — needs careful implementation.

Marketplace challenges in Windsurf apps

Building a marketplace with Windsurf is a great start — but these challenges need attention before launch.

Payment splitting and payouts

Buyers pay, the platform takes a cut, sellers receive the rest. This requires Stripe Connect or similar — significantly more complex than basic checkout. AI tools rarely implement this correctly, leaving you with manual payout processes.

Two-sided authorization

Sellers can manage their listings but not other sellers'. Buyers can view listings but only manage their own orders. Admins can moderate everything. Three distinct permission levels, all enforced server-side.

Trust and safety

Reviews, ratings, dispute resolution, content moderation, and fraud detection. These are complex systems that AI tools don't generate but that make or break a marketplace.

Search and discovery

Users need to find what they're looking for. Basic database queries won't cut it at scale — you need full-text search, filters, sorting, and potentially geolocation. This requires proper indexing or a dedicated search service.

Real-time communication

Buyers and sellers need to communicate. In-app messaging, notifications, and order status updates require real-time capabilities that AI tools often implement superficially.

Data integrity

Inventory counts, order statuses, payment states, and user balances must be consistent. Race conditions (two buyers purchasing the last item simultaneously) require careful database design.

What we check in your Windsurf marketplace

Payment flow — Stripe Connect setup, split payments, seller payouts
Authorization — buyer vs seller vs admin permissions enforced server-side
Data integrity — race conditions, inventory management, order state machines
Search performance — indexing, query optimization, full-text search
Real-time features — messaging, notifications, live updates
Content moderation — reported content handling, admin tools
Security — data isolation between sellers, payment security
Mobile responsiveness — marketplace browsing experience on mobile

Common Windsurf issues we fix

Beyond marketplace-specific issues, these are Windsurf patterns we commonly fix.

highSecurity

Incorrect auth middleware logic

Windsurf generates auth checks that look correct but have logical gaps — missing route protections, incorrect token validation, or bypassable middleware.

highSecurity

SQL injection in raw queries

When Windsurf uses raw SQL instead of an ORM, it sometimes concatenates user input directly into queries rather than using parameterized statements.

mediumBugs

Silent data corruption

Type mismatches between frontend and backend go unnoticed. Data gets saved with wrong types or missing fields, causing issues that surface much later.

mediumBugs

Circular dependency issues

Complex projects generated by Windsurf sometimes have circular imports that cause runtime errors or undefined values in specific conditions.

Frequently asked questions

Can I build a marketplace with Windsurf?

Windsurf is a great starting point for a marketplace. It handles the initial scaffolding well, but marketplace apps have specific requirements — payment splitting and payouts and two-sided authorization — that need professional attention before launch.

What issues does Windsurf leave in marketplace apps?

Common issues include: incorrect auth middleware logic, sql injection in raw queries, silent data corruption. For a marketplace specifically, these issues are compounded by the need for payment splitting and payouts.

How do I make my Windsurf marketplace production-ready?

Start with our code audit ($19) to get a clear picture of what needs fixing. For most Windsurf-built marketplace apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
