Vibe Coding for Marketplaces
Two-Sided Platforms Without a Full Engineering Team
Marketplaces are among the most complex products a non-technical founder can attempt to build with vibe coding. Two user types, separate sign-up flows, payment splitting, dispute handling, and search — each adds significant complexity. It is possible — but the scope discipline required is more demanding than for simpler products. Here is what works, what does not, and how to do it right.
Talk to an ExpertWhat vibe coding a marketplace actually involves
A marketplace has two user types — buyers and sellers — with distinct sign-up flows, different dashboards, and an interaction mechanism between them (listings, bookings, messages, or bids). It requires a payment infrastructure that splits funds between the platform and the seller (Stripe Connect). It needs a search and filtering system. It needs a review or rating mechanism. And it needs moderation tools for the platform operator. Each of these components can be vibe-coded individually. The challenge is that they must all work together — and the interactions between them create edge cases that are difficult to anticipate in prompts. A marketplace MVP should be defined as the minimum that enables one successful transaction between one buyer and one seller, not a full-featured platform.

Why marketplace complexity is a vibe coding test
Marketplaces are the most ambitious type of vibe coding project because the complexity is multiplicative. Adding one new feature to a simple SaaS adds one unit of complexity. Adding one new feature to a marketplace can add five units — because it affects two user types, the payment flow, the notification system, and the admin panel simultaneously. The founders who succeed with vibe-coded marketplaces are the ones who accept a radically constrained MVP scope. They build the minimum to enable one transaction and validate demand before adding any of the features that make a marketplace comfortable to use. Validate first. Polish later.
Marketplace complexity is multiplicative — each new feature affects multiple systems
Successful vibe-coded marketplaces start with a radically constrained MVP scope
Validate one transaction type first — listing, booking, or purchase
Build fluency and discovery features only after the core transaction is validated
How to scope and build a marketplace MVP with vibe coding
The marketplace MVP build requires the most disciplined scoping of any vibe coding project. Follow this sequence:
Step 1 — Define the single transaction type: Service booking, physical goods purchase, or digital download
Step 2 — Build seller onboarding first: Seller creates a listing. That is all — no dashboard yet
Step 3 — Build buyer browsing and purchase: Buyer sees listings, selects one, pays via Stripe Checkout
Step 4 — Add Stripe Connect for seller payouts: Split the payment between platform fee and seller
Step 5 — Build the minimum notification flow: Email buyer (confirmation) and seller (new order) only
Step 6 — Test one complete transaction manually with a real buyer and seller before adding more features
Step 7 — Only after a successful real transaction: add search, filtering, reviews, and dashboards
Marketplace MVPs built with vibe coding
These are representative examples of what is achievable within a constrained scope.
A services marketplace was built using Bolt + Supabase + Stripe Connect in eight days — enabled 15 seller sign-ups and 40 bookings in the first month
A digital goods marketplace used Lovable with Supabase Storage for file delivery — validated demand with 30 sellers before building search or reviews
A local services platform built a complete booking and payment flow in 10 days — discovered the real bottleneck was seller supply, not buyer demand

Common marketplace vibe coding mistakes
Marketplace builds fail most often because of insufficient scope discipline — attempting to build a full-featured platform before validating the core transaction.
Building search and discovery before validating that sellers will list and buyers will purchase
Not implementing Stripe Connect from the start — adding payment splitting after launch is a complete rebuild
Building separate apps for buyer and seller instead of one app with role-based views
Skipping the admin panel — you cannot manage a marketplace without tools to moderate listings and handle disputes
No email notifications for transactions — buyers and sellers need confirmation emails from day one
How to build a marketplace MVP that validates
The minimum viable marketplace is the product that enables one successful transaction between a buyer and a seller, with payment split correctly, and confirmation emails sent to both. That is the target. Everything else — search, reviews, dashboards, recommendations — is iteration. Greta builds marketplace MVPs with this discipline: core transaction first, full code ownership, Stripe Connect configured from the start, and an admin panel that lets the operator manage both sides.
Define success as: one complete transaction, paid correctly, with emails to both parties
Build seller and buyer flows in the same application with role-based access — not separate apps
Implement Stripe Connect from day one — it cannot be added cleanly after the fact
Build admin tools alongside the product — you need to manage the marketplace from day one
