Verdict
Very vibe-codeable as 'my digital products shop.' Harder if you mean Gumroad-the-marketplace with discovery and creator payouts at volume.
What you can rebuild
Product pages, Stripe Checkout for digital downloads, a creator dashboard (sales, customers), and file delivery after payment. Enough for a solo creator store.
What stays hard
Tax/VAT, payout compliance, fraud, discoverability marketplace, memberships at scale, and customer trust around refunds.
Starter prompt
Build a Gumroad-like storefront called SoftShelf. Creators can upload a digital product (PDF, zip, or link), set a price, publish a public product page, and sell via Stripe Checkout. After payment, buyers get a download page and email receipt. Creator dashboard shows sales and customers. Stack: Next.js, Tailwind, Stripe, Supabase storage. Clean creator-economy aesthetic.
Follow-up prompt
Add: discount codes, pay-what-you-want pricing, customer library of purchases, and a simple email broadcast to past buyers. No marketplace discovery feed yet.
