I've tested and actually used so many themes, pagebuilders and sitebuilders over the years. I must say that Cwickly was surprising as I took the time to follow their onboarding wizard. It was well thought out without going into Hollywood blockbuster mode. The right amount of information with an interesting approach of explaining both Wordpress, the site editor, Gutenberg and of course Cwickly. It explains some interesting functions that I have not seen all grouped together in one product. It combines both a theme and a plugin, but you can choose to use another theme with just the plugin. It surprised me to see the option to define what users / roles can access or view. From my first tests, the theme(r) allows you to quickly create pages from a library of templates and the plugin provides some nicely designed blocks. Installation and activation of both plugin and theme was simple and fast. Setting up was a breeze. Documentation is thorough and well structured. I'm sure there is much more to it, but the first impressions are positive. There on Discourse, not Facebook, always a good sign. Support was extremely fast, a few minutes to resolve an issue with stacking codes. It has ACF Pro integrated, that's a novel one.
My first impressions are flashes of exemplary tools like Oxygen and Bricks but seems to be highly aligned with the Gutenberg and the new Site Editor function in WP. I see a bright future with this tool. I am not sure about how this integrates with other key functions, well depends what you are doing, like WooCommerce
Concerns: the first Appsumo campaign was one of the shortest I've ever heard of, not sure why but glad I caught this new one. Spoken to Louis about some unusual naming convention of the actual plugin file generated. The site editor part does seem to be new and with a bit less polished UX than other parts, but then again it is pretty new in WP anyway.
Overall, impressed, and will be keeping this without a doubt.
