Show HN: Agentic Commerce Marketplace Chat

I've been building an open source alternative to Shopify, so it only felt fitting to build in agentic commerce too.

I saw where ChatGPT Checkout was heading, another proprietary marketplace where they control which sellers get access and priority. More gatekeeping, more rent-seeking. It was clear Shopify stores would get preferential treatment.

So I built "the / marketplace," a fully open-source alternative with a flexible adapter system. It already supports Openfront (the Shopify alternative I’ve been developing), but it’s designed to work with any e-commerce platform, not just the ones OpenAI decides to favor. You can bring your own OpenRouter key or connect to Ollama locally, so your shopping data stays private and under your control.

Right now it has 2 demo shops, Impossible Tees and Nimbus Gallery.

As we launch more Openfronts for restaurants, gyms, and other verticals, those should be able to plug into the chat.
