Pros
Pro Open source
Layers is an open source website builder. The source code is freely available on GitHub.

Pro Best in it's class
Speed & Quality webdesign done in your browser.

Pro Semi-collaborative development support
Webflow allows workload to be shared among multiple users. However, you can't leave comments for them.
Pro W3C-compliant HTML5/CSS3
Webflow generates W3C-compliant markup and stylesheets.
Pro Responsive web design with Bootstrap
Because it's based on Bootstrap, it works across all modern browsers & devices.
Cons
Con Requires WordPress
Requires WordPress which is heavy and too bloated for many simple sites.
Con Not a lot of great pre-made themes available
One of the areas that Layers falls behind is the number of good themes that can be found and installed from the marketplace.

Con Based on Bootstrap
Bootstrap is rather old technology
Con Design tool is web-based, not a proper application.
The site doesn't state this explicitly.
Con Can't export your site for deployment unless you pay.
Not unreasonable, but something users should know before investing their time.
Con Uses JavaScript
Webflow uses JavaScript on its websites. Website visitors can have JavaScript disabled and be unwilling to enable it for the website they want to view, which would put a website created with Webflow out of their reach.

Con No way to collaborate on designs with comments

Con No version control

Con Fixed media queries
Webflow has four fixed breakpoints (desktop, laptop, mobile landscape & mobile portrait). The inability to set your own media queries can be limiting. If your layout breaks outside of these four options, you have to export the code and write them yourself.
