Built a marketplace with Firebase Studio?
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 Firebase Studio apps
Building a marketplace with Firebase Studio 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 Firebase Studio marketplace
Common Firebase Studio issues we fix
Beyond marketplace-specific issues, these are Firebase Studio patterns we commonly fix.
Firestore security rules too permissive by default
Firebase Studio frequently generates Firestore rules that allow authenticated users to read and write any document in the database, without scoping access to documents owned by that user.
Client-side security logic that can be bypassed
Access control checks are placed in frontend React components rather than Firestore rules or Cloud Functions, allowing users to bypass restrictions by making direct Firestore SDK calls.
Cloud Function cold start latency degrading UX
Infrequently-called Cloud Functions take 2-5 seconds to cold start, causing noticeable delays on first API calls and making the app feel slow during low-traffic periods.
Unhandled Firestore transaction conflicts
Concurrent writes to the same documents cause transaction conflicts that are not properly caught or retried, resulting in lost updates and silent data inconsistencies.

Frequently asked questions
Can I build a marketplace with Firebase Studio?
Firebase Studio 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 Firebase Studio leave in marketplace apps?
Common issues include: firestore security rules too permissive by default, client-side security logic that can be bypassed, cloud function cold start latency degrading ux. For a marketplace specifically, these issues are compounded by the need for payment splitting and payouts.
How do I make my Firebase Studio marketplace production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Firebase Studio-built marketplace apps, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a Firebase Studio-built marketplace?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger marketplace projects, we provide a custom fixed quote after the audit — no hourly billing.
