Fastn Marketplace Preview is a free Chrome extension that allows users to embed and preview the Fastn.ai integration marketplace within any website or application layout. This tool is particularly designed for internal teams, partners, and early customers, enabling them to test and validate the embeddable integration experience seamlessly without requiring any coding skills.

The extension offers several key features, including the ability to paste a CSS selector and embed URL into a popup, which injects the Fastn marketplace directly into any specified container on the page. It also stores values locally to eliminate the need for retyping, and it dynamically updates the iframe based on user input, making it an ideal solution for internal testing, demonstrations, and sandbox integrations.
