Whenever Wordpress name comes up, Gravity Forms follow. It's probably the most well-known form builder for Wordpress with extensive user base and mostly positive reviews. Gravity Forms pricing is as follows (sorry, no free plan) - $59 for Personal license, $159 for Business license and $259 for Developer license. Of course, if you want CRM, IM or online payments integrations, those are available to you only in the top plan. If you are looking for a free Gravity Forms alternative that gives you these features in the free plan, take a close look at our free Bitrix24 form builder. Bitrix24 is unique, because it combines web forms and CRM in one. It's CMS agnostic and is not limited to Wordpress. In fact, in addition to generating embed code, it creates public form links as well, so you don't even have to own a website. While Bitrix24 CRM comes with web form templates, it is fully customizable and can create any form - Contact Us, Feedback and Idea Suggestion, Resume Submission, Event Registration, Online Ordering and so on.
