Google Chrome Extension for Crosslisting Platform
Budget: $250 – $750 USD
Description
I’m looking for an experienced developer to build a Google Chrome extension for a crosslisting platform I’ve already developed in Lovable.
The web application is functional, and I’m now looking to extend it with a browser extension that integrates seamlessly with the existing platform.
Project Overview
The extension should allow users to streamline the process of creating and managing marketplace listings by interacting with supported marketplace websites while communicating securely with my existing web application.
This is not a project to build the SaaS from scratch—the platform already exists. The focus is the browser extension and its integration.
What I’m Looking For
I’m seeking someone with experience in:
* Chrome Extension development (Manifest V3)
* JavaScript/TypeScript
* Browser APIs
* API integration
* Authentication between a web app and extension
* DOM interaction/content scripts
* Supabase (preferred)
* Experience building marketplace tools or automation software is a major plus
Initial Features
The exact scope will be finalized together, but I’d like the extension to support features such as:
* Secure login to my existing application
* Detect supported marketplace pages
* Read listing information from webpages
* Send listing data to my application
* Populate listing information back onto marketplace pages
* Image handling where permitted
* Settings and account management
* Automatic updates through the Chrome Web Store
Important
* Code must be clean, documented, and maintainable.
* I want full ownership of all source code and intellectual property.
* Please describe how you would architect the extension and how it would communicate with my existing application.
* If you’ve built Chrome extensions before, include links or examples.
Future Work
This project has significant long-term potential. After the MVP, I plan to continue adding features and expanding marketplace support, so I’m looking for someone interested in an ongoing relationship.
