Up until a few years ago, pretty much the only way to have a user-input form on your site was to either code one yourself or download a PHP- or ASP-based form from a site like HotScripts. The whole process was all very code-oriented and entirely unintuitive.
Then, out of the ashes, arose a slew of sites including Wufoo, JotForm, FormAssembly and many others; all designed to make the process of creating forms of all kinds a brilliantly simple, drag-and-drop one.
Of the three aforementioned sites, Wufoo is, by far, my favorite and has proven itself to be both reliable and cutting-edge.
There are two things, however, that might prevent the average individual or freelancer from using a site like Wufoo on a regular basis. First off, the monthly fee can be a bit hefty if you want a decent amount of control over how your form looks and how you retrieve your data. Second, even if you do want to wholly take over the forms you create on the site (in terms of data-retrieval or aesthetics), the process can be a bit daunting even for premium subscribers.
Enter MachForm from Appnitro. For all intents and purposes, MachForm is pretty much a Wufoo clone that sits on your own Web site giving you complete control over where your data resides and how well it integrates into your existing design. In addition, there’s no monthly fee with MachForm. You pay $39 for a site license and with that fee comes free minor upgrades for a year and full support via email.
Like I said, it’s pretty much a Wufoo clone and, therefore, makes creating forms to embed on your site a beautifully simplistic process. Check out some of the screenshots and a demo on the official site: http://www.appnitro.com/machform.
