Effective web forms are a crucial part of any Web site or landing page. They are the window through which site visitors interact with the site. Unfortunately, they can be a pain to create.

The good news is there exists several resources that make developer’s lives simpler by offering complete, on-demand forms and surveys tailored to pretty much any need. In many cases, including a top-notch professional looking form or survey is as easy as embedding a line of HTML.

There are too many good options to list them all, but here are 13. Most have free trials so give them a try and see what works best for you.

3. LeadSwarm

LeadSwarm forms take an interactive spin on the traditional form. Instead of filling in blank fields, the form asks the respondent a series of questions much like a survey. Each question that appears is based on the answer to the previous question, so the form logically branches into different areas. These forms are great for lead capture/generation activities and make a nice alternative to a static contact form.
