Who it is for
A shopper who has found something expensive and wants to see what else looks and functions like it for less.
Overview
Dupe searches for cheaper alternatives to a particular product. The starting point can be a link to a product page, an uploaded photo, or a written description of the item in question.
From that input the app looks for similar items sold elsewhere at lower prices and returns them for comparison. Categories named in the record are fashion, furniture, and home décor.
The premise is price rather than discovery. The item wanted is already known, and what the search adds is a set of substitutes at a different price point.
A shopper who has found something expensive and wants to see what else looks and functions like it for less.
Three different inputs work as a query: a URL, an image, or a plain description of the item.
Availability
Dupe is listed in the ChatGPT apps directory only. Dupe.com has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from Dupe's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with Dupe.com, and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
