Yesterday I released flaskwallet. It is the wallet I use every day to manage my various bitcoin and altcoin nodes. Flaskwallet was designed as a single-user system, no user management exists or is planned at the moment.
Flaskwallet was written with the flask web framework. The code isn't as polished as I would have liked, but I had almost no time to work on it in a few weeks and decided it was good enough to release.
See the documentation for more details and install instructions.
