Marvin

Marvin is a browser extension designed to streamline the process of filling out Stripe's Test Card and payment information during website development and debugging. By auto-filling the commonly used test card number '4242 4242 4242 4242', Marvin saves developers valuable time and effort. In addition to the card number, Marvin can also auto-fill email addresses and cardholder names, ensuring a more efficient testing process.

The extension is compatible with popular browsers such as Chrome, Edge, Opera, and Brave. It is specifically designed to function only when Stripe is in Test Mode, thus avoiding any interference during production. Users can also manually trigger the auto-fill feature from the extension's popup if needed.

Priced at $9.99, Marvin offers a free version as well. The tool promises life updates, ensuring continuous support and improvements. Inspired by the character Marvin from "The Hitchhiker's Guide to the Galaxy," the extension humorously nods to the series' famous reference to the number 42.
