Key Takeaways

- Created by Marty Bent and Moses Finlay, it is now live in the Chrome Web Store with positive community feedback.
Opportunity Cost extension goes live
Marty Bent from TFTC has launched ‘Opportunity Cost,’ a browser extension that allows users to see prices across the internet denominated in bitcoin (satoshis) alongside fiat values.
The extension, which is already available in the Chrome Web Store and soon to be on Firefox, is open source and designed with user privacy in mind.
“Everything within the extension happens in your browser. The only external data that we’re providing is the bitcoin to fiat price conversion at any given point in time. We’re not data harvesting the web pages you’re browsing or the items you’re looking at.”
Building a bitcoin tool for all
The idea began as an augmented reality app but pivoted to a browser extension after feedback from Luke Thomas.
Bent credits the rapid prototyping to advancements in AI tools like ChatGPT and Replit, along with advice from Justin Moon and Anthony Ronning. Developer Moses Finlay completed the app, leading to an official launch and positive community reception.
Bent believes Opportunity Cost serves both bitcoin newcomers and veterans:
It helps the curious understand value in bitcoin terms and gives dedicated users better insight into their spending.
Open source and memetic potential
The extension is fully open source, with code available on GitHub. Users are encouraged to suggest improvements.
Bent highlights its “memetic potential,” noting how sharing screenshots of real-world items priced in bitcoin can enhance awareness.
Bent concludes with an open invitation:
“Please download and use the extension. Let us know what you think.”
