Is there a self-hosted web-based web UI prototyping tool?

The question says it all, we know most of the hosted web-based UI prototyping tools out there, but we would like to have ours hosted on our own internal servers, preferably with on-line multi-user collaboratio开发者_JAVA技巧n functionality (i.e. users modifying the prototype, making comments, etc. in parallel).

Any suggestions will be appreciated.

Sketchflow (in the top-end version of Expression Blend from Microsoft) meets almost all your criteria. It ain't cheap, but it is very powerful.

The deployment package of a Sketchflow build can just be placed on an internal server (no IIS required to deploy).

Multiple users can overlay their comments and pen drawings over the top of the screens. Their feedback is packaged as a unit and sent back. All feedback can then be loaded back into the Expression Blend project and the feedback from 1 or more users viewed overlaid on the correct screens.

It does not meet your multiple-user authoring requirement though, but as they say "too many cooks...".

Most tools are either desktop based or hosted. Seen very few which offer a downloadble multi user version. iRise is one choice with the editor as a desktop product and a centralized server for sharing among users. The budget is typically from $50K to $250K. A similar option exists for Serena composer as well, not sure of the price though.

Both iRise and Serena are not real collaborative tools, the central server is only for sharing the finished prototypes and getting feedback.

If the requirement is for a completely web based multi user tool then 10screens can be an option - http://www.10screens.com. The same product available on the site in a hosted mode can be downloaded and installed on your own servers.
