With iPlotz you can create clickable, navigable wire frames to create the experience of a real website or software application. You can also invite others to comment on the designs, and once ready, you can then manage the tasks for developers and designers to build the project.

It works on windows, mac or linux with flash enabled browsers. You can add, delete, and rename multiple pages for your sitemap. You can drag and drop components onto a re-sizable page, link them or add hotspot links to other pages or external web pages.
You can upload, drag and drop your own images onto a page. It is possible to export pages as png, jpg or pdf. You can invite others to comment on pages. It is possible to share editing rights with others on projects, so that they can modify wire frames too. You can add tasks for project members to handle coding a design.
