Auto Credit Card Filler

Premium autofill tool for web developers. Supports multiple cards and custom project-based field mappings.

Auto Credit Card Filler is a premium productivity extension built specifically for web developers, QA engineers, and designers who frequently test payment gateways and checkout flows. Stop wasting time manually typing out imaginary credit card numbers, expiration dates, and security codes. With Auto Credit Card Filler, you can securely store your test cards locally and auto-fill payment forms with just a single click. ✨ KEY FEATURES: • Floating Magic Fill Button: A subtle floating 💳 icon automatically detects payment forms and lets you inject test data with one click. • Seamless Multi-Card Setup: Store multiple cards (e.g. Test Visa, Test Mastercard, Business Amex) and switch between them instantly. • Dynamic Form Mappings: Every website uses different field IDs. Create specific mappings for different environments (Production, Staging, Stripe, etc.) to ensure seamless autofill everywhere. • Stealth Writing Mode: Bypasses strict bot-detection constraints by emulating realistic, human-paced keystrokes instead of pasting. • "Magic" Generator: Don't have a specific test card? Click the 'Magic' button to spawn a brand new Luhn-valid test card dynamically. • Deep Iframe Support: Successfully pierces through complex shadow DOMs and isolated, secure 3rd-party frames (Stripe, Braintree, Square). 🔒 SECURE & PRIVATE Built purely for testing. Your stored data is saved strictly using local browser storage (`chrome.storage.local`). Information is never transmitted to any external servers, and the extension functions completely offline. (Disclaimer: This extension is intended for developers using mock data in test environments. NEVER store real credit card information inside this extension).
