Namso Gen Extension

Namso Gen & Validator: The Official Extension for Developers

Namso Gen is the industry-leading browser toolkit designed for developers, QA engineers, and security researchers who need 100% Luhn-valid test data instantly. Stop wasting time switching between your checkout tab and clunky web generators.
Built with a Privacy-First Architecture, our extension is the only "No-Permissions" tool on the store. We don’t read your history, we don’t inject scripts into your pages, and we don’t store your data. It is 100% client-side, executing the Luhn Algorithm locally within the popup for maximum sandbox security.

🚀 Why Choose the Official Namso Extension?
* Instant Overlay UI: Generate and copy valid test details (Card Number, CVV, Expiry) via a sleek popup without leaving your active tab.
* 100% Luhn-Compliant: Every number is mathematically verified using the Mod 10 (Luhn) checksum formula, ensuring it passes frontend validation on any gateway.
* Stripe & Braintree Optimized: Specifically tuned for modern gateways. Test 3D Secure redirects, validation error styling, and form submission logic with ease.
* Custom BIN Injection: Manually enter 6-digit or 8-digit Bank Identification Numbers (BIN) to simulate specific issuers or card types (Visa, Mastercard, Amex, Discover).
* Amex 4-Digit Smart Detect: Automatically generates the required 4-digit CID for American Express BINs (34/37) so your tests never fail on CVV length.
* Zero Latency Execution: Native local processing means 0ms delay. No external API calls are made, and no internet connection is required for core generation.

💡 How It Works
The extension mirrors the exact logic used by issuing banks to verify card structural integrity.
1. Drop & Reverse: The algorithm drops the check digit and reverses the sequence.
2. Summation: It calculates the sum of digits based on the Luhn formula.
3. Validation: It ensures the final total is divisible by 10 ($Total \pmod{10} = 0$).

🎯 Perfect For:
* Full-Stack Developers: Testing e-commerce checkout flows and payment integrations.
* QA Engineers: Verifying UI/UX input masks and regex pattern accuracy.
* Security Researchers: Populating test databases with synthetic, non-functional data.
