Founders prototyping a two-sided marketplace (buyers + sellers) with product listings, search, and a cart or inquiry flow.
Stack
A ready-made Marketplace UI you can fork, run, and customize with the prompt pack below.
What's actually inside
The honest engineer's breakdown — what the Marketplacetemplate does, how it's wired, and where it's opinionated.
The Marketplace template is a full buying-side UI: ProductGrid renders responsive listing cards with optimised images via next/image, price, seller badge, and category. SearchBar wires to a keyword filter alongside the CategorySidebar which lets buyers narrow by category checkboxes, condition, location, and a price range. Clicking a card opens the ListingDetailPage — a dedicated page with an image gallery, full description, SellerProfileCard (name, rating stars, listing count), and a Buy Now CTA. The CartDrawer is a shadcn/ui Sheet slide-over that accumulates selected items for checkout.
The honest caveats: cart state lives in component-level state or a context that does not survive navigation to ListingDetailPage and back — items clear unless you add localStorage persistence. The SearchBar filter state also resets on back-navigation because it uses useState rather than URL params; the medium-difficulty prompt fixes both. Another common trip-up is next/image: any external image domain must be whitelisted in next.config.js remotePatterns or the Vercel image proxy will block it with a 400 error.
On the seller side there is no authentication or listing creation flow out of the box — the template is buyer-facing only. If you need sellers to post listings, you will need to add auth and a form; the medium seller-dashboard prompt scaffolds that page.

Fork it and get it running
Forking the Marketplace template takes about 5 minutes. You will open the community page, verify the listing grid renders, tweak design for free, then deploy to a live Vercel subdomain.
Open the community page and fork
Navigate to https://v0.dev/chat/community/b3DN1aOd6mQ in your browser. You will see the Marketplace template with a live preview. Click the Fork button in the top-right area of the community page. V0 copies the full template into a new Project in your account — you need a V0 account but no paid plan to fork.
Tip: Sign in to V0 before navigating to the URL so the Fork button is active immediately.
You should see: A new V0 Project opens with the Marketplace code and the Vercel Sandbox preview loading.
Verify ProductGrid and SearchBar render
Wait for the Vercel Sandbox preview to load in the right panel. Confirm that the ProductGrid shows listing cards with placeholder images, the SearchBar responds to typing, and the CategorySidebar checkboxes toggle the visible listings. Click a card to verify it opens the ListingDetailPage with the image gallery and SellerProfileCard.
Tip: If images show broken icons, this is expected for external placeholder domains — you will fix it in step 4 or by whitelisting the domain in next.config.js.
You should see: ProductGrid, SearchBar, CategorySidebar, and ListingDetailPage all render and respond to interaction in the preview.
Adjust branding in Design Mode
Press Option+D (Mac) or Alt+D (Windows) to open Design Mode. Click the marketplace name in the header, card colour swatches, or button labels to edit them directly on the canvas. This costs zero credits. Update the primary colour and any placeholder copy that should reflect your brand before you start adding real data.
You should see: Your brand name and colours appear in the preview without spending any prompt credits.
Swap in your real product listings
In the V0 chat panel, paste the first prompt from the Prompt Pack below (Swap sample listings with real product data). Include your actual product list — title, price, category, image URL, and any other fields. V0 will update ProductGrid, hook up ListingDetailPage, and keep SearchBar and CategorySidebar filtering wired to the new data.
Tip: If your images are hosted on an external CDN, also ask V0 to add the domain to next.config.js remotePatterns at the same time to avoid the 400 image error.
You should see: ProductGrid shows your real listings with correct titles, prices, and categories after V0 regenerates.
Publish to a live Vercel URL
Click the Share button in the V0 top navigation, then open the Publish tab. Click 'Publish to Production'. The build and deployment take approximately 30–60 seconds. Once complete, you receive a live .vercel.app URL. Open it in a separate browser window to test the full listing → detail → cart flow as a real buyer would.
You should see: Your Marketplace is publicly accessible on a Vercel subdomain with all listing images loading correctly.
Connect a custom domain
Log in to the Vercel Dashboard at vercel.com/dashboard, find your marketplace project, and go to Settings → Domains. Click Add Domain and enter your domain name. Vercel shows the DNS record to add at your domain registrar — typically a CNAME pointing to cname.vercel-dns.com. DNS changes typically propagate within 5–30 minutes and Vercel provisions SSL automatically.
You should see: Your marketplace loads on your custom domain with HTTPS active.
The prompt pack
Copy-paste these straight into v0's chat to customize the Marketplacetemplate. Each one names this template's own components — no generic filler.
Swap sample listings with real product data
Replaces every sample card in ProductGrid with your real listings and keeps SearchBar and CategorySidebar filters functioning against the new dataset.
Replace all sample listings in the marketplace ProductGrid with the following product data. Each listing should display a product image using next/image (add the image domain to next.config.js remotePatterns if needed), title, price, category, and a View button that navigates to the ListingDetailPage for that item. Keep SearchBar keyword filtering and CategorySidebar category checkboxes wired to the new data: [paste your product data here].
Add sold-out badge to ProductGrid cards
Adds visual sold-out state to ProductGrid cards and prevents sold-out items from being added to CartDrawer.
In the marketplace template, add a 'Sold Out' overlay badge on any ProductGrid card where the listing's stock field is 0. Use a red shadcn/ui Badge positioned in the top-right corner of the card's next/image container using absolute positioning. Disable the 'Add to cart' button and grey out the card for sold-out items so buyers cannot add them to CartDrawer.
Persist SearchBar filter state in URL params
Makes all SearchBar and CategorySidebar filters shareable via URL and persistent across ListingDetailPage navigation.
In the marketplace template, update the SearchBar and CategorySidebar to read and write all filter values — keyword, category, minPrice, maxPrice — from URL search params using Next.js useSearchParams and router.push. When a buyer filters the ProductGrid and then navigates to a ListingDetailPage and presses back, the SearchBar should restore its previous filter state from the URL automatically. Do not cause a full page reload on filter change.
Add seller dashboard page
Adds a /seller-dashboard route with a listings management table that sellers can use to track and manage their active ProductGrid listings.
Add a /seller-dashboard page to the marketplace template. It should display a shadcn/ui Table of the seller's active listings with columns: title, price, views, and enquiries. Add an Edit and Delete button per row. Use shadcn/ui Skeleton components for the loading state. Reuse the SellerProfileCard at the top of the page to show the seller's name and rating. Wire to sample static data for now.
Connect Supabase product listings with real-time updates
Replaces static listing data with a live Supabase table, adds RLS policies for buyer/seller separation, and enables real-time ProductGrid updates.
Wire the marketplace ProductGrid to a Supabase table called listings (id uuid, title text, price numeric, category text, image_url text, seller_id uuid, created_at timestamptz). Fetch listings in a Next.js Server Component using the Supabase server client initialised with SUPABASE_URL and SUPABASE_ANON_KEY (no NEXT_PUBLIC_ prefix on the server). Enable Row Level Security so any visitor can read all rows (SELECT policy: true) but only authenticated sellers can insert or update their own rows (seller_id = auth.uid()). Add a Supabase Realtime channel subscription on the client so newly posted listings appear in ProductGrid without a page refresh.
Add Stripe Checkout for marketplace purchases
Adds a complete Stripe Checkout buy flow to ListingDetailPage and a webhook handler that marks listings sold in Supabase on payment completion.
Add a buy flow to the marketplace ListingDetailPage. When a buyer clicks 'Buy Now', call a Next.js Server Action that uses stripe.checkout.sessions.create() with STRIPE_SECRET_KEY, passing the listing price and title as a single line_item. Redirect the buyer to the Stripe-hosted checkout page. Add a /success route that reads the session_id query param and marks the listing as sold in Supabase. Add a webhook handler at /api/webhooks/stripe/route.ts that uses const body = await request.text() (not request.json()) before calling stripe.webhooks.constructEvent() with STRIPE_WEBHOOK_SECRET to handle checkout.session.completed.
Gotchas when you extend it
The failures people actually hit when they push this template past its defaults — and the exact fix for each.
<Image> component shows broken image in Vercel Sandbox previewWhy: next/image requires external image domains to be whitelisted in next.config.js. Sample listings use placeholder image URLs from domains not in the allowlist, so the Vercel image optimisation proxy returns a 400 error.
Fix: Add the image hostname to the images.remotePatterns array in next.config.js, or use local /public images during development.
In the marketplace next.config.js, add a remotePatterns entry that allows images from [your-domain].com so the ProductGrid listing images load correctly in both the V0 preview and Vercel production.
Module not found: Error: Can't resolve '@/components/ui/avatar' after local exportWhy: V0 references shadcn Avatar in SellerProfileCard but the component may not exist in the shadcn registry under the new-york-v4 style used by the template. Running npx shadcn add avatar can return an HTML error page instead of the component JSON.
Fix: Use the GitHub integration and merge the V0 branch rather than running npx shadcn add — this ensures you get V0's exact component source without registry mismatches.
Remove the shadcn Avatar import from SellerProfileCard and replace it with a plain <div> that shows the first letter of the seller name on a coloured background using Tailwind classes.
SearchBar filter does not apply when navigating back from ListingDetailPageWhy: Filter state lives in component-level useState; navigating to the detail page unmounts the SearchBar component and clears state. Back navigation re-mounts it with empty defaults, losing the buyer's filters.
Fix: Store filter state in URL params (useSearchParams + router.push) so the SearchBar restores its state from the URL on re-mount.
Refactor the marketplace SearchBar to read and write its filter values (keyword, category, minPrice, maxPrice) from URL search params so filter state persists across navigation to ListingDetailPage and back.
Hydration mismatch on ProductGrid — server and client render different item countsWhy: The grid uses Math.random() or Date.now() to generate placeholder data at render time. The server and client produce different values, causing a React hydration error in the browser console.
Fix: Move random data generation into a useMemo hook seeded with a stable value, or fetch data from a Server Component and pass it as props to the client grid.
Fix the hydration mismatch in the marketplace ProductGrid by moving all dynamic data generation to the server side and passing it as props to the client component.
CartDrawer does not persist items across page navigationWhy: Cart state is held in local component state or a context that is destroyed on full-page navigation events. Navigating to ListingDetailPage and back empties the drawer.
Fix: Use localStorage to persist cart items and rehydrate in a useEffect on mount, initialising cart state as an empty array to avoid SSR errors.
Persist the marketplace CartDrawer contents to localStorage so that refreshing the page or navigating back from ListingDetailPage does not clear the cart. Initialise cart as an empty array and load from localStorage inside useEffect.
Template vs. custom — the honest call
A forked template gets you far, fast. Here's where it holds up, and where you'll outgrow it.
The template is enough when
- Startup validating the marketplace concept with a clickable prototype before building backend
- Developer who needs a polished listing grid, search, and cart UI scaffold to wire their own API to
- Community marketplace with fewer than 100 listings where static data or a simple Supabase table is sufficient
- Freelancer who needs a client-ready marketplace demo in hours, not days
Go custom when
- You need seller KYC, escrow payments, dispute resolution, or review moderation
- The platform needs multi-currency pricing, tax calculation per jurisdiction, or VAT invoicing
- You expect catalogue scale above ~1,000 SKUs where Algolia or Elasticsearch is required for search
- Seller onboarding, Stripe Connect payouts, and multi-tenant dashboards are core requirements
RapidDev specialises in extending V0 marketplace prototypes into production systems — seller onboarding, Stripe Connect payouts, and Supabase backend included. See rapidevelopers.com.
Frequently asked questions
Is the Marketplace v0 template free to fork?
Yes. V0 community templates are free to fork with any V0 account, including the free tier. You can preview and edit without spending paid credits until you start prompting for changes.
Can I use this template commercially — for example, to build a marketplace for a client?
Yes. V0 community templates are MIT-licensed, so you can use the code commercially, charge clients for the build, and modify it freely without any attribution requirement.
Why does my fork break in the Vercel Sandbox preview after I add real images?
The most common cause is a missing next.config.js remotePatterns entry for your image domain. next/image blocks any external domain not explicitly whitelisted — you get a 400 error or broken image icon. Add your CDN hostname to remotePatterns and the preview will load correctly.
How do I connect a real database to the marketplace?
Use the advanced 'Connect Supabase product listings' prompt from the Prompt Pack above. It instructs V0 to create a listings table with RLS policies, fetch data in a Server Component, and add a Realtime subscription so new listings appear without a page refresh.
Does this template support sellers posting their own listings?
Not out of the box — the template is buyer-facing only. Use the medium 'Add seller dashboard page' prompt to add a /seller-dashboard route with a listings management table. For seller authentication and listing creation, you will need to add Supabase Auth or Clerk.
Why does CartDrawer empty when I navigate to a listing detail and come back?
Cart state is held in local component state that is destroyed on navigation. Use the 'Persist CartDrawer contents to localStorage' fix prompt to add localStorage persistence with a useEffect rehydration — this keeps items across navigation without any backend.
Can RapidDev build a production marketplace from this template?
Yes. RapidDev extends V0 marketplace prototypes into full production systems with Stripe Connect payouts, seller onboarding flows, and Supabase backends. See rapidevelopers.com for details.
Outgrowing the template?
RapidDev turns v0 prototypes into production apps — real auth, database, and payments — at $13K–$25K.
