I really like the team behind Fast Simon. They're super supportive, and I appreciate the spirit of the company and the way they work. Their AI engine and personalization capabilities in particular are impressive. It's quick and easy to set up and get going, and support is always there if needed. Review collected by and hosted on G2.com. What do you dislike about Fast Simon? The no code editor is extremely inefficient. It's a good idea and does the trick for a lot of basic things, but very painful to use for detailed and nuanced styling. And if that's the only way to style things like the SERP, then that's a problem. So, the NCE needs to be much more improved. Review collected by and hosted on G2.com. What problems is Fast Simon solving and how is that benefiting you? Fast Simon effectively serves up the right results to customers based on what they're looking for.

I like that it can handle a very large catalog, and I also appreciate the Turbolinks feature. Review collected by and hosted on G2.com. What do you dislike about Fast Simon? What I find most frustrating is the lack of documentation for customizing the app. On top of that, there isn’t a directory of developers who have experience customizing it, especially at an affordable price.
