Hi,
Our plugins are Elementor (Free) and Elementor Pro.
Unfortunately, we cannot recommend any third-party plugin as we do not provide support for them, but you are more than welcome to join our Facebook community (https://www.facebook.com/groups/Elementors/ )and check with our users what plugins and themes do they recommend there
I’d also suggest you check out our Elementor Community forum, we have created it to connect Elementor users together and share knowledge
