Pro Open source
Layers is an open source website builder. The source code is freely available on GitHub.
Pro Ability to add custom CSS
While designing a whole website without coding is possible with layers, for more advanced users who want to inject custom CSS to their website, it's possible to do so through a plugin called DevKit.
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.
