Marvin — Auto-fill Stripe's test card and payment info extension

Hello there, hunters! 👋 As many of you may know, when developing a website with Stripe applications, you must enter the test card number '4242 4242 4242 4242' to test payments. You also need to input an expiration date and CVC... and it turns out that '4/24' is now an invalid date, so the friction has increased since you can no longer simply type 42 in all the fields 😵‍💫 During the development, testing, and maintenance of your product, you may have to do this hundreds of times! That's why I created Marvin, a simple browser extension that automatically fills in the payment info, email, and cardholder name to test payments with just one click and eliminate all the friction. I hope you enjoy it and would love to know your thoughts 😃

It's always a bit tedious to repeatedly enter test payment information, and this extension seems like a perfect solution to streamline the development and debugging process. Congratulations on creating something that not only saves time but also reduces the potential for errors during testing.

This is a very useful tool. Previously, when I needed to perform this operation, I always had to search for a credit card information generator on Google, or use one of my zero balance cards. Congratulations on the launch! Our own product will also be launching payment-related features this year, so we should be able to use it.

That's the spirit man, Love it ahah

Does it also work for lemonsqueezy ?

The idea is great but the reference to H2G2 is an automatic upvote. You won at the life, the universe and everything else.

Small, but a valuable time-saver. Great job. Just an idea, but you could easily extend this to be usable with Paddle and/or LemonSqueezy. 🙂 Congratulations on the launch!

I just finished my product that's launching here on Tuesday. Testing the stripe link. LITERALLY thinking "I'll bet someone has made an extension that does this (inputs the test card info)" hahaha nice job

This is the tool I was missing. Great job, Juanjo! Congrats on your launch!

Weirdest SaaS idea, that I might actually buy

Great! Hate spending time on filling dummy card values, it will help a lot. Congratulations on launch!

Congratulations on your launch! Your product seems very interesting.

A pretty handy painkiller for devs, specially those who ship often. Congrats on the launch 🚀

Congrats on the launch! That's a handy one! Just bought it :)

Great idea! It is simple and yet super useful 👍 kudos Juanjo!

Congrats! Nice idea!

Super useful! Thanks

My friend that's a great idea!

Nice idea! Definitive time saver.

Oh this is good stuff! We've filled in that test info maybe a hundred times. This would've been so convenient!
