I've been using websites like Netvibes and start.me as personal dashboards for a while.
They are fine, but I'm now looking for an open source alternative that I could host myself on a server and occasionally modify/extend it with new widgets.
I would love one written in Node.JS, Ruby, or Python, although anything else would be fine too.
The widgets I currently use are the RSS Reader and the Note (a persistent, directly editable text field).
I have searched the web for such apps but could not find any. If there are CMS apps that can do this, I'd love to try them out.
