I have never created a browser extension before, and I wanted to learn the process and what the SDLC looks like in the extension world. As I began exploring the topic, I came up with an idea of turning it into an open-source framework for creating coupon browser extensions called OpenCoupon. This framework can enable anyone to create a Google Chrome coupon browser extension similar to Honey, from which I drew the inspiration.

As I delved into the inner workings of Honey, I found a multi-part series investigation done on Honey by a YouTube journalist MegaLag, where he exposes unethical business practices and technical exploitation done by the extension. This led me to creating the framework with ethics, transparency, and privacy in mind.

This is also the first complete project that I created with Anthropic Claude Code utilizing agentic coding and workflow, which was fun to explore and learn the capabilities and limitations of the approach.

The project is open-source and welcomes feedback and contributions. If anyone have any questions, comments, or suggestions, I would be more than happy to hear and address them.

Huge thanks to MegaLag for the amazing investigative journalism done on PayPal Honey
