I have a bit of a love-hate relationship with Webflow. As a designer, I LOVE that the interface allows me to create websites without requiring me to write code (my coding skills are more basic).
That said, saying that Webflow requires no coding is a bit of a misnomer. True, you don't have to code or know code to use Webflow, but if you don't have a pretty solid understanding of HTML5/CSS/structure/lingo, you're going to be, frankly, screwed. Sure, you can go into the interface, and with only minimal review of their info materials (eg. tutorials), create a website from scratch. But, if you don't know what you're doing (eg. say, you typically do graphic design and work with Adobe photoshop or InDesign) - you'll be duped into thinking the beautiful site you made (that looks great on your screen) will look just like it looks on your screen everywhere else - and you'll be WRONG. I had to spend a lot of time really learning about how to use px vs. % vs. VH vs. em's and things like that to really be able to make my websites responsive. Now, that said, they really do have a TON of tutorials and videos and webinars out there to help you, so if you are willing to put in the time, you can learn what you need to know. One of my favourite features is that you can go into the editor of other sites and see how they are built. It's a really cool way to learn more (in a reverse engineering kind of way). I really, really love this feature and appreciate that they decided to make this available.
The bit of "hate" part of my relationship with Webflow stems from 2 things: the time required to really learn the system (to find some of the subtle design techniques that are really critical to responsiveness, you have to hunt and peck - there's no one tool I found that really goes into this in detail from A to Z), as well as some issues I've had with their support. But I've updated that part of my review (see below). All in all, I don't see myself not using Webflow anytime soon. It's one of those situations where you have to take a bit of bad with the good, because it's worth it.
This is an update... I'd had an experience with support where I hadn't gotten a response to an issue for some time (and if you read on the forums, you'll see I'm not alone in that experience). However, I was able to get through to them via an alternate route, and from that point on, it was like I was a VIP. They were really timely with their responses, and I had a fantastic phone conversation with support - which was uber helpful (and uncovered a bug on their end which may have been impacting other users). So, I'm going to recommend them more strongly, but with the caveat that customer service can be an issue (I was told they are hiring more people, so this may be alleviated soon), so you just have to be persistent and try reaching out by other means if at first you don't succeed with the support email.
One other important point: they have had a lot of changes in pricing structure in the past year which has upset the community (see many forum posts) and left designers hanging about future price changes/competitiveness of using the platform. I don't do web design full-time, but I understand why this is a significant issue. In fact, I just built a website for a company who is most likely not going to host with webflow because of the high price. It's still a great platform, and it's easy to export static sites, but if you're going with CMS, then just know your clients will be paying a more premium price.
Watch out for the pricing changes that are going on now. Webflow used to be $5 for hosting a static site, and $10 for CMS. They went through several changes last year - to both designer plans and hosting - and are set to increase hosting in April: static site for $12 and CMS for $20. That puts them above industry competition (eg. hosting a WP site on Blue Host or other hosting platform). While you can always export your code and host yourself, that obviously won't work with sites that are CMS. Just a heads up.
Great tool to make custom websites from scratch. It's not "idiot proof" like Wix or other web editors, but there's a lot you can do with Webflow that you can't do with those if you take the time to learn it.
