Every marketplace shares the same spine — vendor onboarding, discovery, split payments, gated payouts, reviews, moderation and AI. What changes is the transaction slot: what's sold and how it's delivered. Marketrail runs two slots today, each with its own live demo marketplace.
Each engine is the full Marketrail spine with a different transaction slot — and each runs a seeded demo marketplace you can browse, buy from and sell on.
Physical goodsLive demo: Maker Market
Browse, add to cart, check out — the seller ships.
Handmade ceramics, textiles, woodwork and prints from independent makers.
Variants with their own stock, decremented atomically with the charge
Cart grouped by shop, shipping per shop
Order tracking, status emails & packing slips
Refunds return the money, reverse the split and restock
Fits: Etsy-, eBay- or Faire-style marketplaces, local goods, multi-vendor retail.
Buyers, sellers and operators each get their own surface — the same three in every slot.

Automate. Split. Scale.
The money splits itself —in every slot.
Set your commission once and every sale is a Stripe destination charge: the buyer pays, the platform keeps its fee, the seller's share lands in their own account. The money code is identical across engines — only what's being paid for changes.

Four guarantees, every engine
Marketplace complexity,handled.
Whichever slot you run, the same four rules hold — enforced once in the shared code, not rebuilt per engine.
The split is right
Fee and share come from the same pure money code in every engine — subtotal equals fee plus share on every order.
Payouts are gated
Money only routes to sellers whose Stripe payout capability is verified. No leaks.
Refunds reverse everything
Money, fee and share come back in one replay-safe action — and the goods restock or the license is revoked.
The spine stands alone
Discovery, shops and moderation never import the transaction layer. A seam test enforces it — that's why slots swap.
AI on every surface
AI drafts,the seller's factsfill the gaps.
The AI layer is part of the spine: every engine ships it, under the same rules. Every feature proposes; a person clicks to accept. Nothing is written without a human — nothing is invented, and nothing can't be traced back.
Human in control
AI proposes. You decide. You click. We save.
Built on trust
Grounded, validated, and never writes to your data.
