I bought it as a replacement to FormEngineer (also from Appsumo) that disappeared. I previously tried a more expensive product from Appsumo, expecting better results, but it lacked important features, leading me to try Deftform.

Deftform has all the features I needed, and much more. The UX is simple and intuitive, so I was able to create and try my first form in minutes. It offers many options to meet my needs, such as custom CSS, HTML insertion, webhooks, regex validation, predefined answers via links, and more.

The UX is well organized, separating the simple features from the more advanced ones for more technical users. The documentation is concise and effective.

It is immediately clear that it is a polished product crafted by professionals with long experience in actual needs. You can quickly set up an email for routing the form and be ready in minutes. I would expect to get a simple message telling me that one more form was filled. Instead, I got a detailed message including the answers and a link to the attached files, which saves me a lot of time.

This is surely the best form application I have ever used.
