A Working Marketplace App from a Prompt
VULK generates a marketplace app from a prompt: listings, search, user roles for both sides of the market, messaging or booking flows and a PostgreSQL backend — a working two-sided product you can put in front of real supply and demand.
Marketplace-shaped software is core platform territory: e-commerce and booking apps together account for roughly 8% of 11,355 generated apps, and 62% of all apps ship with a SQL schema (VULK platform data, July 2026). A marketplace needs exactly that — real data on both sides of the market.

The complete prompt
Adapt this brief to your business, then build and refine it in VULK.
Build a marketplace for renting photography equipment locally. Owners list equipment and availability; renters request dates; both sides track approval, cancellation and return status. Include these capabilities: - Listings with photos, categories, search and filters - Two-sided roles — providers and customers with separate views - Booking, enquiry or checkout flow matched to your model - PostgreSQL-backed users, listings and transactions - Deployable web app with full source export Build the complete working project with its routes, data model and interactions. For saved or private data, implement persistence, authentication and server-side permissions. Keep API credentials on the server. For external services, document the required setup and use test mode until real accounts are connected. Do not present a simulated integration as a completed live connection. Make the interface responsive, with accessible labels, keyboard navigation and visible focus. Include loading, empty, validation and error states. Use clearly labelled sample data, never invented customer testimonials or results. Choose a visual direction suited to this project and keep typography, spacing and controls consistent. Explain how to run, test, export and deploy the source. Verify this end-to-end flow: Request overlapping dates for one item from two accounts. Prevent conflicting confirmed rentals and update availability correctly after a cancellation.

FAQ
Which marketplace models fit best?
Service marketplaces, booking marketplaces, rental platforms, local commerce and niche product markets. For a product-catalog multi-vendor store specifically, see the multi-vendor marketplace page — the generated data model differs.
Does it handle payments between the two sides?
VULK generates Stripe-ready checkout surfaces and integration code paths. Split payouts, escrow and KYC are production decisions you configure with your payment provider before launch.
Can I start with one city or niche?
Yes — and you should. The generated app is yours to iterate: constrain categories and geography through conversation, validate, then extend the exported code as the market grows.
