Wufoo is a web-based tool to help you build and host amazing online forms. In only a few minutes, you can create a mailing list, survey, or even a customer management system.
For now in the beta version of Wufoo, Beta Accounts can create 10 forms, use 25MB of disk space for file upload, utilize all field types in their forms, and collect an unlimited amount of entries. If you need more, let us know and we’ll work something out. For those worried about what’s going to happen to your stuff when Wufoo goes live, don’t worry. They will not delete any of your forms or entries (you’ll always get to keep what you collected and used during beta), but you will lose the ability to create some forms and be limited by the features of the plan you settle on. So, for example, if you decide that you just want to use the free plan after beta, you won’t be allowed to use file upload anymore.
I think its very usefule for Indian Organisations which doesnt have any chance yet to host their sites online and needs window form submission.
There’s a more recent and detailed review of Wufoo, including a live data-entry form and several screen captures, plus links to other AJAXified formbuilders at http://oakleafblog.blogspot.com/2006/07/wufoo-challenges-infopath-for-form.html.
Another site you should look at is The Blue Form (http://www.theblueform.com)
TheBlueForm is a process automation site that lets businesses manage forms like timesheets and expense forms. You can create forms using an AJAX form builder and then assign approval workflows to them. When users fill-in a form, the approver is notified and the form can be tracked through its workflow.
