The people have spoken. Their approval has us seeing stars - and we couldn't be prouder. With validation like this, Formidable Forms is one of the highest-rated WordPress plugins out there.

The plugin works perfectly. It offers you many configuration options and is very well structured. But the best thing about Formidable is the technical support. I needed a really special feature, and thanks to them I achieved it. They have gained a customer for life.

I've been using Formidable Forms and Views and have been delighted with the many ways I've been able to utilize them. Using Views to display form submission data on the front-end has been huge for me. And, the few times I've gotten stuck, I've reached out to support and have received actual, helpful responses.

FF has transformed the way I approach form creation and management on my website. The visual editing capabilities give me intuitive and seamless design processes that save me time and effort. Next to that, the ease of creating multi-step forms that have better conversion rates makes setup a breeze. The overall flexibility and efficiency of Formidable Forms have significantly improved my workflow and site user experience.

I’ve been using formidable for almost ten years, on over a hundred websites. It’s the most refined form builder with the most flexibility than any other I’ve used. Plus, it’s just beautiful and just works.
The support framework our this plugin is top notch!
