Test Payment Flows Without Real Cards

Generate mock Visa, MasterCard, RuPay & Amex test cards. Simulate success, 3DS, insufficient funds, and network timeout scenarios. Free REST API for payment testing.
Hey guys
I built MockCard.io because I was completely blocked waiting weeks for payment gateway approval just to test my webhook flow. Frustrating as hell.
So I built mockcard.io: generate mock Visa/MC/RuPay/Amex cards, pick any scenario (success, 3DS challenge, insufficient funds, timeout…), and it auto-delivers realistic webhooks to your endpoint.
No more stalling dev work. Works for Dodo, Razorpay, Stripe-style integrations, or anything else.
Free tier to start (10 anonymous gens lifetime, 500/mo verified), Pro $14.99/mo for heavy use + webhook retry/visualization.
Would love brutal feedback—does this solve a real pain for you? What scenario do you wish it had? Try it and let me know.
Thanks for checking it out! 🚀

How to test webhooks on your local development environment using Mock Card? Explained in detail here: https://mockcard.io/blog/testing-payment-webhooks-locally-mockcard. Webhooks silently fail and that can cause production flow to fail. See, how Mock Card helps in such scenario.
Just pushed a big update to MockCard.io
Now you can keep your production payment flows safe, retain customer trust, and finally sleep peacefully at night.
The new Chaos Simulator lets you toggle real failure modes (duplicate webhooks, race conditions, latency storms, 3DS abandonment, limbo states and more) and instantly see the exact webhook your server would receive.
Try it free (no signup for first 10 generations): https://www.mockcard.io
Screenshots of the new Chaos Simulator attached.
Feedback welcome — what failure mode are you most worried about in your app?
