What website builder do you use? Is it usable by non-developers, or do you prefer to roll your own HTML/CSS?
I have use https://daftpage.com/ for https://www.dovfordev.com, in this case I was validating the idea, I really like draftpage, it is really easy to use.
But also I have created http://pauapp.com which is using Gatsby and Material u, and I dont think Daftpage could provide what I need to get what I have on this page. If I had to start with my product again, I will use a website builder to validate the idea and maybe stick with it until the product demands for more.
So I think it depends on what you are looking for (a generic answer on the tech world right? haha)
Anyway, here is a list of some useful website builders you could look at
Some cools website builders
I built https://versoly.com/ for this.
Every website builder is focused on non-technical users and ignore developers. That ends up with the best devs working on custom code.
Versoly has a code editor built in to import/edit/export code. The CSS is Tailwind so very clean.
The other side is headless CMSs that make it easier for devs, but provide terrible experience for non-technical users. They end up using another landing page builder for marketing.
