A JavaScript Remote for Bitcoin

bitcoin-js-remote is a user interface for Bitcoin written in JavaScript and released under the MIT/X11 License. It works in most modern browsers as well as on Android and iPhones. If run on an Android phone it can scan QR codes containing addreses to send Bitcoins to! If you don't own an Android device, you can still enter raw bitcoin: URIs in a textbox.

For SSL support a small server side script written in Python is required. You can also use Apache to serve js-remote.

You can try out the demo using this link or by scanning the QR code on your phone:
