Can I vibecode KFA Marketplace?
NOT REALLY · don't botherThe software is the vibe-codeable part: listings, cart, Stripe checkout, shipping labels, seller payouts. An agent can stand all of that up in a weekend, and the consolation prompt below does. What it cannot stand up is the market. KFA is a two-sided used-keyboard exchange where every board passes through a warehouse for inspection and PCB testing before the buyer sees it, and the fee pays for that inspection and for the crowd on both sides. A clone launches empty.
Build me a small two-sided marketplace for used mechanical keyboards like KFA Marketplace, for a community I already have. Requirements: - Django + SQLite, server-rendered templates with vanilla JS, no frontend framework, one process. - Sellers post listings: board name, condition notes, up to 8 photos, a fixed price, and a shipped weight in pounds. Single quantity, sold means gone. - A /moderate queue: new listings stay hidden until I approve them. - Stripe Checkout for purchase; verify the webhook signature and mark a listing sold only when the payment event lands, not on redirect. - On sale, buy a label through the EasyPost API from the seller's address and the listing weight, then email both sides the tracking link. - A seller ledger: each sale credits the seller's balance minus a fee percentage from .env; a /payouts page shows what I owe whom, paid out by hand and recorded manually. - Stripe and EasyPost keys in .env; Django's built-in auth for buyers and sellers, no telemetry, everything on my own server. - Out of scope: escrow, buyer protection, dispute flows, and inspecting anything. Trust between strangers is my problem, not the app's. - README with setup, stripe listen webhook config for local testing, and the fee math.

Nobody pays KFA for its Django code. Sellers pay 6.5% + $1 to reach buyers without eating scam risk, and buyers pay 6.5% for a used board that a human has opened, inspected, and PCB-tested before it ships. The free alternative is r/mechmarket, where trust is flair count and PayPal disputes; the fee is the cost of turning that into a guarantee.

What do I lose by replacing KFA Marketplace?
Honestly: liquidity: buyers and sellers who are already there, which is the product; warehouse QC: every board is inspected and its PCB tested before delivery; buyer protection backed by that inspection instead of a seller's photos; payout operations: KYC, earnings ledgers, and withdrawal handling; fraud and dispute handling when a deal goes sideways. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to KFA Marketplace?
Yes: Mercur (Multi-vendor marketplace software you deploy yourself; vendors, buyers, and the warehouse remain your problem.) r/mechmarket (Where used keyboards already trade for free; protection is seller flair, PayPal G&S, and your own skepticism.) The prompt is for when you want it exactly your way.
