Rails-grade catalogs meet the AI checkout.
Spree is the most established open-source Rails commerce platform — multi-store, multi-vendor, headless-friendly. xpay reads your Spree admin, publishes a clean AI feed, and routes agent purchases through your existing storefront and checkout.

People are asking ChatGPT and Google what to buy instead of searching. Those AIs answer — but they don't send buyers to your store. The brands listed inside those AIs make the sale. Everyone else watches.

Your customers are asking AI "what's the best yoga mat?" or "find me a birthday gift under $50." If your products aren't inside those AI assistants, you're invisible to your next customer.

Google Gemini answers the shopping question — but sends buyers to bigger brands who are already in the system.
With xpay: your products appear inside ChatGPT, Gemini, and 4 other AI assistants — and the buyer pays you directly.
The right shape for the platform you already run.
Spree is the established choice for Rails-fluent teams who want a commerce platform they can read, fork, and extend without inheriting baggage. Multi-store and multi-vendor are first-class, the Storefront API is mature, and the surrounding ecosystem (Vendo, Wombat, marketplace gems) gives you serious freedom. xpay slots into that as one more Spree engine: install via your Gemfile, authorise the catalogue read, and your products start appearing inside ChatGPT, Gemini, Claude, and Perplexity. Multi-store brands get per-store feeds. Marketplaces can opt vendors in progressively. Agent buys land in your existing Spree storefront — default or fully headless — and your checkout keeps doing what it does today.
