Recurly.js is an open-source Javascript library for creating great looking credit card forms to securely create subscriptions, one-time transactions, and update billing information using Recurly. The library performs in-line validation, real-time total calculations, and gracefully handles errors.

Your customer stays on your website while their billing information is securely sent to Recurly for approval. Because the cardholder data is sent directly to Recurly, your PCI compliance scope is dramatically reduced. The Recurly.js project also includes examples for updating billing information and performing one-time transactions.
